I am working in a UAV-Team and my task is following and locking another UAV autonomously. I coded my opencv part and I used background substitution method and several filters. I can get absolute result from my code (like to forward go left , go right). My question is how can I send this result to the UAV's motors. How can I communicate with my UAV with C++? I've read lots of documentation from ardupilot, ardurov, opencv and pixhawk. But still couldn't figure it out.

Connect your microprocessor(i.e rasberry Pi) with pixhawk ans use mavlink communication protocols to send command here is link And you can use dronekit also to do that.

  • Is set_rc_channel_pwm() function in MAVLINK safe? Because giving some instructions to pwm usually damages the engine. – Türker Berke Yıldırım Feb 21 '19 at 10:33
  • Yes RC is safe but applying directly may cause trouble. – Talha Farooq Feb 21 '19 at 16:12
  • Sir may you give a specific function that i can use; my bachelor is computer science and really doesn't understand about communication issues. I can take x and y coordinates by using OpenCV (from the object should i track) and my middle point of my frame is set as (0,0) so. if the coordinate +,+ region. I want to set my motors direction to +,+ region. But which function should I use? I am using MAVLINK and ArduSub as firmware. – Türker Berke Yıldırım Feb 21 '19 at 20:56
