How can connect APM with RaspBerry Pi for image process

Hey i have a project with UAV and my professor wants to an image processing i don’t know how can connect do you have a schematic or something guys what should i know for making this project ?

Raspberry can do the work (camera and image processing). Go look Rpi forum for that.

Pixhawk is an autopilot. No image processing there…

Pixhawk and Raspberry can exchange information (Position, flight data,…) via serial connection.

You use the term “APM”. APM is an old autopilot, no more supported. If you really want to develop a valid project, look for recent hardware (cf Ardupilot documentation).
