Obstacle detection method and device for aircraft

Abstract

The invention discloses an aircraft obstacle detection method and device, which are used for reducing the obstacle detection error of the aircraft and improving the obstacle detection accuracy of the aircraft. An embodiment of the present invention provides an obstacle detection method for an aircraft, comprising: collecting images of target obstacles in real time through a binocular camera configured on the aircraft to obtain a first image and a second image, wherein the first image is obtained by The left eye in the binocular camera is taken, and the second image is taken by the right eye in the binocular camera; the first pixel position of the target obstacle projected in the first image is determined, and the second pixel position of the target obstacle projected in the second image, and calculate the difference between the first pixel position and the second pixel position according to the first pixel position and the second pixel position the disparity value between the first pixel position and the second pixel position, and calculate the depth value of the binocular camera from the target obstacle according to the disparity value between the first pixel position and the preset disparity depth mapping matrix.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an obstacle detection method and device for an aircraft. Background technique [0002] Unmanned aircraft is referred to as aircraft for short. Aircraft has many applications in national economy and military affairs. At present, aircraft has been widely used in aerial photography, power inspection, environmental monitoring, forest fire prevention, disaster inspection, terrorism and lifesaving, military reconnaissance, In the field of battlefield assessment and other fields, the aircraft is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but it is equipped with autopilot, program control device, information collection device and other equipment. The remote control station personnel track, locate, remote control, telemetry and digital transmission through radar and other equipment. [0003] In the...
