dragon-eye is an F3F aeromodelling competition real-time electronic judging system with Jetson Nano . It’s base on technology of computer vision, capture video stream from camera then detect moving objects and keeps tracking them, once one of the tracking target across central vertical line, trigger out a signal.
For F3F there are two dragon-eye bases and a timer needed. So I made an Android APP to control ,setup dragon-eye base and also be the timer that can play audio & voice.
I made various update and bug fix for months. Please refer to my blog
