I'm trying to figure out optical flow feature.
My goal is to be able to track a certain element using computer vision, something like this:
i have search the forum/web and found a few sites that explain how to connect px4Flow and LIDAR to the pixhawk in order to be able to control the UAV(for example):
I'm trying to understand how does the PX4FLOW is communicating with the arduPilot and tell it how to operate ?(i'm not asking about i2c/ SPI/serial, i'm asking what data/frames the pixhawk controller is getting and what does it do with it?).
hope that someone can help me with some info about the process.
Thanks in advanced,
