PhotoModeler 2018.1 Release and Drone Vertical Datums

Posted on Wednesday, April 18th, 2018

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), or two points assigned (translate and scale). Evaluation System Improvement. Evaluation codes are now 30 days long and are easier to get. UI Speed Improvements. A variety of user interface speed improvements have been made. Drone Vertical Datums The title of this article mentions drone vertical datums – what does this have to do with the 2018.1 release?  First, what is a vertical datum? A…Read More

Why use Photogrammetry for Surveying and Mapping?

Posted on Tuesday, January 23rd, 2018

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. In recent years, however, interest in photogrammetry among surveying professionals has been enjoying a major boom. This trend has been catalyzed by the rise of affordable, commercially available aerial drones, or UAVs for short. UAVs provide a number of advantages which make photogrammetry even more accessible, and has led to a renewed interest in the technology. To understand why, let’s first take a look at…Read More

With a Camera and a Drone Audit a Mine Reclamation

Posted on Monday, July 10th, 2017

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 by the company or by an agency, may be aided with aerial photography and 3D surface modeling. The topography of most mining sites makes it difficult for field experts to collect data needed for site mapping. Climbing one quarry face after another to take measurements using GPS systems or other survey tools is a labor-intensive, time-consuming, and dangerous activity. Use of unmanned aircraft systems (UAS)…Read More

Efficient and Accurate Mapping with a DJI Matrice

Posted on Tuesday, May 2nd, 2017

PPK (Post Processed Kinematic) GPS is a great way to increase the accuracy of drone work and reduce per-project costs. There are PPK units available for a number of drones including the for the DJI Matrice 100 and 600 UAV drones. This PPK unit, along with PhotoModeler’s PPK integration, provide excellent accuracy in ground surveying with minimal ground control. To get high accuracy with a drone photo-based survey, one usually needs to place and survey several ground control points spread across the area. Ground control points are either man-made targets (e.g. large cross) that you place on the ground before the flight, or visible natural features, and both surveyed with a high accuracy instrument (total station or RTK GPS). Minimizing or…Read More

Survey Grade Accuracy with a Drone without Ground Control !

Posted on Tuesday, November 8th, 2016

To get high accuracy with a drone photo-based survey, one usually needs to place and survey ground control points. Ground control points are either man-made targets (e.g. large cross) that you place on the ground before the flight, or visible natural features, surveyed with a high accuracy instrument (total station or RTK GPS). To achieve 2 cm to 4 cm ground accuracy from your drone survey over the whole area usually requires 10 or more ground control points. These ground control points (GCPs) require travel over the whole site, take time to place, survey, and optionally remove, and thus are an expensive method. Any way to reduce ground control requirements is money and time in your pocket! How can you reduce…Read More

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

Posted on Monday, January 19th, 2015

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 your site for your photogrammetric project.   A scene can be shot with a UAS at various heights, with more flexibility, less risk, and significantly reduced cost than a piloted aircraft. UAS-based photogrammetry is great for larger landscapes, and objects that are difficult to capture from the ground. PhotoModeler is a software tool for converting photographs into accurate and useful 3D data. Accessible UAS camera platforms…Read More

Tip 26: Create an UAV ortho-photo mosaic in PhotoModeler

Posted on Monday, November 26th, 2012

UAVs (Unmanned Aerial Vehicles) and drones are big news these days, not only in military use but more so with many new commercial and public safety applications. With cost-effective fixed-wing and multi-rotor UAVs capable of carrying camera payloads coming on the market, the sky has literally been opened to new possibilities! Aerial photogrammetry was once the sole purview of full-size manned aircraft with expensive aerial photogrammetric cameras. Now relatively inexpensive and intelligent UAVs (fixed-wing and multi-rotor) that can carry consumer and prosumer cameras have changed who has access to aerial mapping systems, instead of limiting their use only to large budget projects. Examples of UAV photogrammetry are golf course mapping, large accident scene diagramming, mining documentation, and stockpile volume measurement.…Read More
