Drone Imagery to 3D Game Engine and Virtual Reality

We’ve updated our sample page to include a Blender project with the high resolution Red Rocks virtual reality scene. We’ve also added a download link to the .OBJ, .MTL and .PLY files for import into Unity3D or other 3D rendering software. Creating real world scenes in VR quickly from drone imagery is possible using an oblique collection and our processing software.

The image above shows a 3D Textured Mesh Point Cloud converted to .OBJ format displayed in Blender. The .OBJ has an associated .MTL and .JPG file to provide the texture and material mapping.

Precision Agriculture and Calibrated gNDVI

Here we show a set of illustrations for a crop seed research field imaged with a modified near infra-red sensor. The first image shows the scene in the infra-red and the second shows the computed scene gNDVI. The research field was outfitted with a unique set of controls. Aerial targets on the ground provided calibrated spectral reflectance as well as precise geo-spatial position. These were used over the 17 week growing period (on a weekly basis) in order to produce a meaningful temporal history of the research crop maturation.

The third image shows the automated binning of the plot average vegetation indice with color highlighting high indice (green) to low (red). The fourth image shows the 3D model of one plot prior to harvest where average crop height was computed and an estimate of biomass volume obtained.

We believe the key in using spectral imaging effectively in precision agriculture is the correlation with what the agronomists are seeing on the ground. So, high correlation coefficients are mandatory. DroneMapper can help you sort through what works for precision AG imaging. Give us a call!

Big Data Photogrammetry Processing

Processing billions of pixels over large areas at high resolution requires serious computing power and algorithms. The image above shows an Orthomosaic map with a Ground Sample Distance (GSD) of 3 cm spanning an area of over 250 acres. The original imagery was obtained using a Precision Hawk fixed wing UAV system and processed by DroneMapper cloud.

Drone Mapping with Trimble GPS RTK Base and Rover

DroneMapper recently acquired Trimble GPS RTK Base and Rover systems for ground survey to augment its aerial imagery collection operations. By combining ground truth, aerial targets and photogrammetric processing one may produce near survey grade digital elevation models (DEMs) and orthomosaics, precisely geo-referenced. Picture 1 illustrates the RTK setup. To get acquainted with the system operation we performed a number of surveys around the DroneMapper business property.

A search of the National Geodetic Survey (NGS) (https://www.ngs.noaa.gov/NGSDataExplorer/) identified three (3) high precision control points located at Blake Field airport, just north of Delta, Colorado. Picture 2 illustrates the control points on the NW side of the airport runway which is about 1 mile long. We utilized the base station to acquire Wide Area Augmentation System (WAAS) coordinates over the 1V9A monument and found the reported WAAS position was within 1 meter of the precise location in XYZ. We then keyed the precise position of the monument into the base station and used the rover to measure the other two monument positions.

If your application requires high quality imagery collection combined with precise control for the highest geo-spatial accuracies please call the DroneMapper team.

Drone Mapping: Coal Age – Stockpiles – DroneMapper & Arch Coal Featured

Drone Mapping: Coal Age – Stockpiles – DroneMapper & Arch Coal Featured – December 2nd, 2017

DroneMapper offers an affordable solution designed to enable continuous stockpile monitoring at any sized operation,Pierre Stoermer, CEO, said. The company’s main offering is photogrammetric software. “Either we process imagery for the client or the client licenses our Windows-based application(s) for their own use,” he said. “We also offer end-to-end training on drone and camera selection, use of aftermarket applications for autonomous, high-quality imagery collections, imagery processing and extraction of value-added info using GIS software.” Unlike many of its competitors, DroneMapper has already broken into the coal space.

For the last five years, Arch Coal used DroneMapper to process drone-captured images and data from its West Elk site. Arch also tapped the company to demo drone-based solutions at Thunder Basin, in northeast Wyoming. “They are interested in volumetrics, but they are really interested in safety and measurements of toes and crests, and to get measurements of slopes to determine if a slope is dangerous for cave-in,” Stoermer said. The demo went well, he said. “Arch Coal has provided positive feedback.”

DroneMapper is finalizing a white paper that will reveal how drone-based stockpile volumetrics solutions cut costs compared to traditional methods and facilitate continuous monitoring, Stoermer said. Toward both ends, multiple reports can be generated within a workday, empowering the miner with near-time actionable data, he said. To get there, the miner can purchase a perpetual license for the software ($2,000), run its own flights and handle its own data. “With a drone overflight, and if they did the processing themselves, they could eliminate the latency of sending images to us,” he said. “They could utilize our software process right after they collect the data and yield results within two to four hours or maybe less.”

The company offers training, which usually runs two days. It also offers exclusive online tutorials and hassle-free support, Stoermer said. “Our greatest differentiator is that you can speak with a human nearly anytime for support and there is no smoke and mirrors communicated.”
