So if you are getting annoyed by photogrammetry problems due to poor lighting or shadows you can always attach a LIDAR unit to your multicopter for precise point clouds… I think its safe to assume that it will be rather expensive considering a basic LIDAR like the Hokuyo’s UTM-30LX costs about $5k 
. But still another cool use for mapping with a drone!
