Title:
PHOTOGRAPHING PROCESSING METHOD FOR UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/045326
Kind Code:
A1
Abstract:
Disclosed is a photographing processing method for an unmanned aerial vehicle. The method comprises the steps of: aim a camera of an unmanned aerial vehicle at a target; record a first reference pattern; record a second reference pattern; synthesize a three-dimensional reference pattern of the target; when the unmanned aerial vehicle detects a control signal interruption, a focusing frame automatically traverses images in a viewfinder frame and respectively compares said images with the three-dimensional reference pattern, and if the target is not found, the location of the unmanned aerial vehicle is automatically adjusted until the target reappears in the viewfinder frame of the camera; preset a reference straight line between the camera and the target, and control the unmanned aerial vehicle to move along the reference line; calculate a measured distance between the camera and the target; if the measured distance is greater than a preset reference distance, control the unmanned aerial vehicle to continue moving towards the target until the measured distance is less than or equal to the reference distance. The present invention can improve quality of photographing when the unmanned aerial vehicle moves out of vision.
