I need to implement a system in which my copter will fly 10 meters forward and then back to the takeoff point without GPS, only using optical flow and a compass, accuracy ± 1 meter is sufficient. Is there a way to do this using standard methods, or is it necessary to use an esp32 microcomputer?
Yes this is possible using optical flow and the “standard methods” you may have in mind. Not sure what you mean by an “ESP32 microcomputer” and would be good if you clarify what this ESP32 is supposed to do.
Enable optical flow and use a rangefinder with a useful range of at least 10m. Done.
