Abstract

The invention discloses an obstacle detection method of an aircraft and a device. The method and the device are used for reducing obstacle detection errors of the aircraft and improving obstacle detection precision of the aircraft. The embodiment of the invention provides an obstacle detection method of an aircraft. The detection method comprises steps of carrying out real-time image acquisition on a target obstacle through a binocular camera configured to the aircraft so as to obtain a first image and a second image, wherein the first image is obtained through shooting of a left eye in the binocular camera and the second image is obtained through shooting of a right eye in the binocular camera; determining a first pixel position, in the first image, of the projection of the target obstacle, and a second pixel position, in the second image, of the projection of the target obstacle, and calculating a parallax error value between the first pixel position and the second pixel position according to the first pixel position and the second pixel position; and according to the parallax error value between the first pixel position and the second pixel position, and a preset parallax error depth mapping matrix, calculating a depth value between the binocular camera and the target obstacle.

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...
