All ODM needs is a centroid Lat/Lon from the EXIF tags on each photo. You can optionally add a text file that gives a pixel an exact Lat/Lon. From this it matches features from the photos to calculate the exact pitch, yaw, direction. I think you can specify those in the EXIF but it is really hard (i.e. expensive) to get these to high enough quality to render the final image. In our case the high quality gimbals where more than our drones. (~$15k each)
