The algorithm design and implementation of optical navigation device for UAV

The research object of this paper is the optical navigation devices unmanned aerial vehicle (UAV), its function is tracking specific target detection based on the optical image information, so as to realize the precise of the UAV guidance, make its landing on a particular target. The whole boot process can be divided into two parts: tracking guide and landing guide. First, set a specific guidance target, when the UAV tracking the target, the optical navigation device finds the target, then directs the drone to the target. When the drone reaches the top of it, it enters the descent stage, and at this time the optical navigation device needs to ensure that the drone stabilizes the airspace above the target and directs the drone to land on the target eventually.
