Improving machine vision in robotic systems for large-scale sensing in forestry is more relevant than ever. Currently, most UAVs are equipped with various navigation systems (SN), including optical ones. Automatic return-to-point systems are also widely used. These systems are used to facilitate piloting by aircraft, or activated in case of emergency situations. There are also optical tracking systems for the object, which are used mainly in video shooting. Optical navigation systems can be used to more accurately position spaces, and can also be used as a backup navigation system when the main navigation system fails.
