Drone Photography

PhotoModeler Release PhotoModeler version 2018.1.0 was released April 11th, 2018. It has a number of large and small improvements and fixes. UAV Control Marking Improvement. UAV and drone projects with GCP (ground control points) are now easier to set up. Multi-point Transform Improvement. Multi-point transforms can now be formed with just one point assigned (translate), […]

Why use Photogrammetry for Surveying and Mapping?

Photogrammetry UAV Camera Station Layout

Photogrammetry has a long history of use in the surveying and mapping field. Photogrammetry can be used for point measurements or for generating point clouds. Compared to its chief rival, LiDAR (Laser Imaging, Detection and Ranging), point-cloud generation from photogrammetry is cost-effective, portable, and versatile, so it has always had a loyal following among practitioners. […]

With a Camera Measure, Monitor, and Document Bridges

The process of monitoring the health of bridges demands reliable measurement techniques. Traditional methods of monitoring the conditions of bridges are disruptive and may cause inconvenience to users. In addition, the approaches are labor-intensive, and the results are usually less accurate. Considering that there are many transportation structures that require routine monitoring, it is a […]

With a Camera and a Drone Audit a Mine Reclamation

Mining companies are often required to restore mine sites to economically usable conditions after extracting minerals. This process, usually referred to as mine reclamation, involves rehabilitation and other processes that minimize the environmental impact of mining. The reclaimed land can be used for agricultural, recreational, commercial, and residential uses. An audit of the reclaimed site […]

With A Camera Perform Accurate and Detailed Surveying

Surveying is an essential process in mapping, mining, construction, and architecture. This time and labor intensive process involves using a wide range of traditional and modern equipment to obtain measurements. Depending on the nature of the task, the required accuracy, and the challenges involved, a surveyor can use a tape measure/roller, a total station, a […]

UAS / UAV Photography for 3D Scanning, Measurement and Modeling

With the proliferation of UAS/UAV (unmanned aircraft systems, unmanned aerial vehicles, or drones) armed with lightweight cameras it has become much easier to capture, scan, measure and 3D model scenes from above. The technique is called photogrammetry. You no longer need to hire an airplane to take aerial photos or purchase expensive aerial photos of […]
