The rain has finally subsided so I went out to the RC field for some quadcopter fiddling and testing.
The below video shows a quick demonstration of the Region Of Interest (ROI) function of Arducopter (running firmware v3.1.5). I demonstrate the function on the Steadidrone 2014 QU4D with 3DR Pixhawk and GoPro 3 Silver. The function allows the nose (and camera) of the quad to keep pointing at a designated point while flying an autonomous flight plan. In the video there is an explanation of how to set up the the ROI flight plan in Mission Planner as well as a demonstration flight with telemetry data provided by the 3DR 433Mhz Telemetry system.
These technologies still amaze me every day.
