四旋翼飞行器是一种小型、灵活的无人飞行器,其在完成多种工作时需要借助飞行器的实时工况信息,所以现场画面信息的实时传送是十分必要的。本方案通过飞行器搭载路由器和USB摄像头进行数据采集,并通过地面路由器进行接收、发布到internet上。通过该方案,在地面上设置固定轨道,实现飞行器自动巡线飞行。 Quadrotorcraft is a small, flexible unmanned aerial vehicle that requires real-time working condition information of the aircraft when performing a variety of tasks. Therefore, real-time transmission of scene information is necessary. The program through the aircraft equipped with a router and USB camera data acquisition, and through the ground router to receive, publish to the internet. Through this program, a fixed orbit is set on the ground to achieve automatic patrol flight of the aircraft.
