I'm constructing a multirotor drone and want to introduce follow me feature, are there any open source solutions I can use for that purpose? Please note that I want the tracking algorithm to be autonomous based on some video processing and sensors.
No. Several companies tried, failed, and went bankrupt.
Also NO because there are device specific needs (if not using a fob) such as:
- what is the camera
- onboard processor/FPGA
- FC is important because you need to interface discretely
I am confident it is possible, but where the technology stands right now you will need to roll your own.
Expect to see these operations grow, in the past few years small and affordable LIDAR has become real. Generally we need components and APIs to stabilize so people can effectively write code against a stable system.
Watch the Parallax, Sparkfun, and similar communities generally centered on Arduino development. I anticipate projects crossing over with those people.
