Running OpenDroneMap

To run OpenDroneMap on your images move to a directory of images and run the following command:

../OpenDroneMap/run.pl

if your images are with capital letters in there extension first run this command to rename the images:

rename 'y/A-Z/a-z/' *

then the run script

Sit back, grab a coffee and wait

You may also use OpenDroneMap with ground control, in which case you need to create ground control point file.

The gcp_list.txt file is an optional file that allows OpenDroneMap to georeference the textured mesh and create an orthophoto. The input format specifies the x, y, and z of locations in the input images. The format is as follows.

coordinate system description
x1 y1 z1 pixelx1 pixely1 imagename1
x2 y2 z2 pixelx2 pixely2 imagename2
x3 y3 z3 pixelx3 pixely3 imagename3

e.g. for the Langley dataset:

WGS84 UTM 10N
544256.7 5320919.9 5 3044 2622 IMG_0525.jpg
544157.7 5320899.2 5 4193 1552 IMG_0585.jpg
544033.4 5320876.0 5 1606 2763 IMG_0690.jpg

Please note, these locations are not the locations of the camera at the time of the image. If you have this instead, use scripts like these https://github.com/mapillary/mapillary_tools/tree/master/python for inserting that information into your image headers (exif).

Once this file is in place, running is just as easy. Run the script:

../OpenDroneMap/run.pl

Sit back, grab a coffee and wait.
