Overview:

We've developed an aerial ground control point target system similar to a QR code. Our GCP targets are digitally encoded fiducial markers with computer vision software functionality to enhance workflows and provide the highest accuracy possible for photogrammetry missions.

Build:

Download and build opencv3 and opencv_contrib.

Next, build geoBits with the following commands:

$ mkdir build ; cd build

$ export OpenCV_DIR=/opt/OPENCV3_DIR/; cmake ...

$ make

Use:

$ ./build/drnmppr-detect-marker -d=0 -i=img/DJI_0040.JPG -l=0.161 -dp=detector_params.yml
DM-0 img/DJI_0040.JPG 1644.65 2391.85
DM-1 img/DJI_0040.JPG 2049.15 1130.93

Notes:

Printable 10000x10000 pixel markers are in the markers directory.
