DRONES FOR PHOTOGRAMMETRY

HOW ARE DRONES BENEFITING TOPOGRAPHERS?

Collect data five times faster than traditional methods.

Increase efficiency and improve safety

Using a drone for surveying work has many benefits - it helps you acquire accurate data quickly, safely and economically, which in turn can improve decision making and provide vital information.

Thanks to their ability to acquire data from above, drones have been successfully integrated into surveying workflows to perform land surveying, photogrammetry, 3D mapping, topographic surveying and more.

Drone surveys can benefit from many applications in different sectors, such as construction, mining and aggregates, agriculture, urban planning and land management, public safety and environmental research.

Data acquisition with a drone is up to five times faster than land-based methods and requires less manpower.

But what is a drone survey, what data can you collect from your unmanned aircraft, how can it help you, and what are the best drones to use for this type of mission?

“What would have taken the surveyors about eight hours, I took about two hours with the drone. You also have the cost savings of paying one person instead of a three-man crew . The combination of surveying, drones and CAD information allows us to visualize our designs in ways never seen before. We provide our team with the big picture and information they need to share information more effectively and make better decisions . "

Michael Lambert, VDC Manager at Chasco Constructors

‚ÄúThe stocks are spread over a large area and are of various sizes and heights. The¬†detection with a drone is 90% faster . A miner would normally walk the work area with a surveyor's total station and measure not only the stock area, but also the various heights of the material. But above all, i¬†drones significantly reduce the number of workplace hazards employees are exposed to ‚ÄĚ.

WHAT IS A DRONE DETECTION?

Conduct overhead surveys with UAVs.

Put simply, a drone survey is an aerial survey conducted by a drone and is becoming more and more popular.

Using downward-facing sensors, such as RGB or multispectral cameras or LiDAR payloads, drones can quickly acquire a large amount of data. An analysis showed that drones can collect data 97% faster than manual methods.

This data can be used to create a variety of assets, such as 3D maps and elevation models, and extract valuable information such as highly accurate measurements and volumetric calculations.

This information helps make informed decisions and provides valuable information, including identifying errors or problems, keeping up with the progress of a project, and monitoring plant health.

Drone surveying has become such a valuable tool, it is used for land surveying, rooftop inspections, bridge / building surveys, infrastructure maintenance and on construction sites.

"Drones enable companies to create highly accurate point clouds and maps, discover costly errors on site and anticipate planning delays, saving up to tens of thousands of pounds a week."

Richard Clement, Komatsu

‚ÄúBy using drones, we have created a much more efficient process. We can literally take weeks off the schedule, our projects are of much higher quality than before and are safer ‚ÄĚ.

Jim Gorrie, CEO Brasfield & Gorrie

WHY USE A DRONE FOR DETECTION?

Improve efficiency, save money and improve security.

Promote business workflows

There are many advantages to using a drone to make a survey, especially compared to traditional methods.

Simply put, drones are more efficient than traditional ground-based methods, improve workplace safety, and are able to reach areas that would often be prohibited.

These benefits drive workflows and business results and maximize ROI.

“Drone footage helps simplify project management. It took my team just a few days to complete site mapping with drones, speeding up project planning with more accurate site data. "

Grant Hagen, VDC Director, The Beck Group

Find out how drones can transform your detection missions:

More security

Drones greatly increase safety. Why send you to inspect a roof or climb on an escort when a drone can do the job for you?

Using drones for survey work also means you don't need to put out as many ground control points - in some cases, you don't need them. Not only is it a great time saver, but it's also a huge safety benefit by reducing the need for staff to access potentially dangerous areas of your work site.

Wayne Hughes, Balfour Beatty drone pilot, said: ‚ÄúDrones make quantity acquisition and inventory measurements safer. Drones take people away from places where they could be in danger and it means we don't have people bypassing the supplies. Instead, drones can fly over the site and then generate a model, which we can review in the office ‚ÄĚ.

More efficient and cheaper

Acquiring data with a drone is much faster than using techniques in the field and requires less manpower. Using RTK (real-time kinematics) or PPK (post-processed kinematics) technology also saves the arduous and sometimes dangerous task of placing large numbers of ground control points.

For example, Balfour Beatty used drones in a Smart Motorway development, including inventory measurement. The company said it would take a surveyor about a day to measure inventory and process data using traditional handheld equipment. But using the drone, the complex could be flown in 15 minutes, and the model could be processed in about two hours.

Using drones means delivering survey results faster and, consequently, at a lower cost.

Russell Byrd, Virtual Design and Construction Coordinator at Brasfield & Gorrie, said, "Our project and safety teams can now complete walkthroughs remotely, increasing safety and awareness without ever having to go on site."

Reach inaccessible places

Drones can reach places that humans cannot. They can also fly at a much lower altitude than manned aircraft or satellite imagery. This is a particular advantage if you have cloud cover.

Highly accurate data that can be shared

Drones collect highly accurate data.

A drone flight produces thousands of measurements, which can be represented in different formats (orthomosaic, point cloud, DTM, DSM, contour lines, etc.). Each pixel of the produced map or point of the 3D model contains 3D geographic data.

Basically, this information can be stored and shared quickly, which aids in team-wide decision making and communication.

Monitor the progress of a construction site and improve resource productivity

Drones provide an overhead view of a site, providing a complete snapshot of the area and offering useful insights.

Running regular flights through a project allows your team to track progress and identify any errors or problems. Basically, these problems can be spotted early, helping you make quick and informed decisions.

Drones offer a unique view, which you wouldn't get from the ground, and are able to cover an area faster and safer than traditional ground-based methods.

Matthew Forster, Project Engineer for Choate Construction, said: ‚ÄúThe drone maps give my team a bird's eye view of the site, which looks very different from being on the ground. It gives them a complete picture ‚ÄĚ.

Balfour Beatty deploys drones on a smart highway

Balfour Beatty used drones, including the DJI Phantom 4 RTK, during a £ 212 million Smart Motorway upgrade on the M6.

The international infrastructure group used UAS for faster stock measurements, informational reports on aircraft progress and access to hard-to-reach areas.

The use of drones has helped the company improve safety, increase efficiency, collect data faster, improve resource productivity, and achieve highly accurate results.

Drones have proven their worth when it comes to measuring inventory volumes; not only contribute to efficiency, but also improve safety.

“Drones save a lot of time. Let's take the recycling compound for example. If we were to measure inventory with traditional survey tools, it would take much longer to measure the site and collect data, while drones allow the team to fairly make quick measurements of different types of materials and earthworks. "

Craig Matthews, Principal UAS Manager for Balfour Beatty

Atkins uses a bespoke DJI drone for detection

Greater efficiency, greater safety and reduced costs: World-renowned engineering and design company Atkins is benefiting from drones, including a custom-built DJI M600 Pro with a Sony RX1R II sensor.

Pairing the 42MP high-tech camera with the drone and a high-precision Global Navigation Satellite System (GNSS) provided a bespoke solution to meet Atkins' specific tracking requirements and enabled the company to acquire and generate accurate and repeatable data.

The company says that, compared to traditional survey methods, drones dramatically reduce the amount of time the survey team spends walking around the site, reducing or even eliminating the time spent working in potentially hazardous environments.

“While we still use airplanes and helicopters in many of our larger projects, drones allow us to mobilize faster and reduce costs when surveying small and medium-sized sites. We are also able to capture higher resolution images, down to less than cm from drones compared to 2-3 cm from manned aircraft, and combine mapping and inspection surveys in the same site visit, increasing efficiency. "

James Fleming, geomatics consultant (UK and Europe), at Atkins

DJI drones transform visual sensing work

Quayle Industries uses the DJI M210 V2 series with the DJI Zenmuse Z30 zoom payload, as well as the X4S and X5S imaging cameras, for a variety of drone surveys, including roof inspections, power cable checks, and tracking progress of the site.

Using DJI technology, Quayle Industries is able to do their jobs faster, easier and safer than traditional methods, keeping people away from potentially dangerous situations, accessing hard-to-reach areas, and providing unique perspectives.

For example, Quayle Industries used the M210 V2 with the Z30 for this roof detection, pictured on the right. The image on the left shows the view from the drone, high above the building, while the image on the right is a crystal clear image of two of the chimneys, captured using zoom.

This method has numerous advantages. Firstly, the inspection can be completed without having to send team members to the roof, improving safety.It is also a great time saver, as information can be gathered much quicker with a drone than from someone having to board. on top of the building to inspect the scene. This also helps with costs.

And while this technique is time-effective, it doesn't skimp on quality, as the Z30 detects every detail of the two fireplaces, which in turn helps with inspection.

“If you need an asset inspection, drones can take high definition photos that show the condition of the property. This is perfect for roofs and other difficult to access areas. We provide high definition photographs or 4K video of any infrastructure that needs to be checked for damage. By using a drone, you eliminate the need for elevated work platforms or scaffolding, reducing costs, time and, most importantly, risks. The zoom level achievable with the Z30 is exceptional. "

Quinton Quayle, Quayle Industries

WHAT KIND OF RESULT CAN YOU GET WITH A DRONE DETECTION?

Transform drone data into a range of digital assets to provide you with key information.

Improve your workflows

Depending on your choice of data sensors and software, drone detection can produce a variety of results with use cases across many industries. Here is a selection:

2D map

map2d

Survey software can merge hundreds or thousands of digital photos captured by your drone and produce high quality 2D orthomosaic maps.

Having a 2D map can be useful for a variety of reasons and can be used in a wide range of industries, including construction and infrastructure.

By having a drone take hundreds or thousands of photos, you will not only create a complete map, but you will also have a large collection of individual high definition images.

These maps and images give you a real-world view, helping you quickly make decisions and analyze how a project is progressing.

3D mapping

map3d

A point cloud is a 3D view made up of thousands or even millions of georeferenced points. Point clouds provide high-resolution data and offer an interactive 3D model with real-world images. This will help you inspect your job site, for example.

Using 3D data allows you to produce a digital surface model (DSM), a digital elevation model (DEM) or a digital terrain model (DTM).

Point clouds can also be used to develop digitized models of structures for CAD and BIM purposes, something that is at the forefront of modern construction.

Volumetric detection

Drones can be used to create volumetric models, useful for example for stock measurements.

Traditional stock measurements when using GPS or total stations are inhibited by the limited sampling data that can be collected. Instead of using a point grid with a point every 5 meters, a drone can collect a point with a sample distance from the ground of 1 cm creating a much better and more accurate sampled dataset.

Thermal detection

thermal_image

Detect with a thermal imager and quickly identify targets with anomalous thermal signatures.

Thermal investigations can help identify heat losses in order to improve energy efficiency; it can identify water leaks or moisture infiltrations or faults in wiring and other electrical components.

LiDAR map

lidar

Equip your drone with a LiDAR camera to produce a high-density point cloud, giving you useful information about the shape of the Earth and its characteristics.

A LiDAR map is useful for industries such as forestry and agriculture / landscaping.

Visual detection with drone

Drones can be used to produce visual reliefs. You can perform a visual drone survey and a drone inspection to check power lines and roof inspections.

Using a drone to do this is more efficient, cheaper and safer than traditional methods.

DETECTION DATA PROCESSING WITH DRONES

Maximize your data collection.

Generate digital models to drive business results

When surveying with drones, images of the terrain are taken from multiple observation points. By processing these images, photogrammetry software can then create orthomosaics and 3D models, from which it can accurately measure distance, as well as surfaces and volumes of physical objects.

Drone mapping software is a key part of your drone tracking operations, turning the data you have collected into meaningful assets that aid decision making.

Image processing can be a lengthy process depending on the number of images and the performance of your computer.

HOW ACCURATE IS A DRONE DETECTION?

Get centimeter-level accuracy.

You can rely on drone data

Drone detection solutions can produce varying degrees of accuracy, depending on the project requirements.

In an independent study by DroneDeploy, the DJI Phantom 4 RTK achieved a relative vertical accuracy of 2cm and a relative horizontal accuracy of 1.20cm.

An accuracy report with customer Heliguy Terra Drone Europe also showed that the DJI Phantom 4 RTK can achieve accuracy of 3cm-4cm without the need to lay any ground control points.

For some applications, such as crop growth control or construction progress, high relative accuracy is sufficient. For other jobs that also require absolute high accuracy, there are drones equipped with Real-Time Kinematic (RTK) and Post-Processed Kinematic (PPK) capabilities. When combined with some ground control points, detection accuracy can be achieved.

“Not only can you get accurate results, but in most cases using the Phantom 4 RTK for surveys will reduce the costs associated with traditional methods, including those spent on labor, hardware and software. This also goes hand in hand with the overall benefits our customers have gained, such as increased productivity, faster turnaround times, better collaboration and greater workplace safety. "

Verdict: DroneDeploy after testing the accuracy of the DJI Phantom 4 RTK

What is the distance of the sample to the ground (GSD)

Ground Sample Distance (GSD) is the terminology used to describe how much ground distance is displayed between each pixel center of the image. For example, if the GSD is 1.5cm, every single pixel on the image refers to 1.5cm square on the ground.

GSD depends on two factors:

  1. Flight Height: The higher you fly, the higher your GSD becomes.
  2. Camera Resolution: The higher the resolution, the better the ground detail that can be shown in the photograph, which means a lower GSD.

It is also important to remember that if your project requires specific accuracy, your GSD should not exceed it. For example, if you are aiming for a final relative accuracy of 2cm, your GSD should be no more than 2cm.

WHAT ARE THE GROUND CONTROL POINTS?

Helps to capture accurate drone data.

RTK can reduce the need for GCPs

When it comes to obtaining detection level accuracy from drone mapping, using GCP has traditionally been the primary method.

Ground Control Points - or GCPs as they are known - are marked points on the ground that have a known geographic location.

For aerial survey applications, GCPs are typically required as they can improve the positioning and accuracy of mapping results. In fact, the GCPs allow the survey drone to obtain fairly accurate data.

GCP

However, taking this approach has its drawbacks. This method can be laborious, as it requires the precise arrangement and geolocation of numerous checkpoints, and can require a great deal of preparation. In some cases, more time is spent laying GCPs than conducting the drone mapping itself.

There is a way to minimize or eliminate the need for GCP, which is to use corrective RTK and PPK technologies. And drones like DJI Phantom 4 RTK and M300 RTK benefit from this technology to simplify drone detection missions.

Taking this approach can eliminate, or certainly reduce, the number of GCPs needed. Using this technology can save 75% of the time and money spent on drone mapping setup, it has been estimated, and can lead to centimeter-accurate data.

DRONE MAPPING USE CASES

“The unique selling point of the DJI Phantom 4 RTK is that it is able to record the exact set of coordinates at the time of image acquisition using RTK GNSS. This reduces the number of ground control points needed, reducing the amount of time it takes to be on site while maintaining the same level of accuracy. "

PPK VS RTK

Which is best for your drone detection missions?

Drone pilots can take advantage of PPK (post-processed kinematics) and RTK (real-time kinematics) during surveying and mapping projects. But what's the difference?

RTK is a GPS correction technique that provides real-time corrections to location data when the surveying drone is capturing photos of a site. Real-time correction is a major industry advantage.
PPK is another GPS correction technology technique that works to correct location data, in the cloud after the drone data has been captured and uploaded.
In other words, this means that in terms of position correction, RTK does it during the flight, while PPK makes the changes later.

ppk_rtk

RTK has many advantages, such as aircraft millimeter accuracy during flight and accurate geolocation of information captured by the aircraft.

However, RTK requires a very specific base station and other equipment working together to process data in real time, and signals can be blocked resulting in loss of correction data. This is not a problem with PPK.

PPK also removes the requirement for GCPs saving additional time in the field.

SURVEY WITH AND WITHOUT RTK

Here is a breakdown of the benefits of using a drone with RTK, compared to relying only on ground control points or piloting a UAV without RTK.

Perhaps the best combination is to deploy a drone with RTK and a small number of strategically placed ground control points.

Having piloted the DJI Phantom 4 RTK, Terra Drone Europe believes that in some cases the accuracy that can be achieved without any GCP is less than 3-4cm, but when more accuracy is needed, it is advisable to use a number of control points - but it is still a reduction compared to traditional detection methods.

PHOTOGRAMMETRY WITH DRONE VS LIDAR

Choose the right solution for your needs.

In drone detection missions, the choice between photogrammetry (above, right) and LiDAR (below, right) depends a lot on your mission and budget.

Drone photogrammetry is when a drone captures a large number of high-resolution images over a specific area. You can use these images to reconstruct the terrain in 3D using image overlay and sufficient ground control.

Photogrammetry is best for mapping, probing, mining, wide coverage combined with high horizontal and vertical accuracy.

In contrast, LiDAR (which stands for light sensing and beam) is a remote sensing technology that uses rapid laser pulses to map the surface of the earth.

LiDAR is useful when used to create high resolution digital surfaces, terrain and elevation models used for various business applications.

Both photogrammetry and LIDAR can provide remarkable levels of 3D model accuracy, especially compared to terrestrial sampling methods.

lidar-1
lidar-2

A big advantage of photogrammetry is that this technique not only generates accurate 3D models, but also full-color and high-resolution information for each point in that model, providing a clear visual context.

This makes interpretation and analysis of the results much easier than with a pure LiDAR point cloud.

However, when it comes to detecting dense soils, where light pulses can still penetrate between branches and leaves, LiDAR obtains highly detailed information.

This is a major advantage over photogrammetry, as photogrammetry can only produce accurate surveys when sparse vegetation is present on the site. Although LiDAR has similar limitations, in good conditions it can penetrate areas with up to 90% vegetation. (Photogrammetry approaches 60%).

One of the biggest differences between photogrammetry and LiDAR is the price.

Thanks to innovation, LiDAR has become a much more accessible solution than before. That said, it still comes at a price and is a more expensive solution than photogrammetry.

A drone-based lidar system can save you tens of thousands of pounds, while a DJI Phantom 4 RTK will cost a few thousand pounds and is easier to use.
