Abstract

Based on computer vision and neural network technology, the present invention innovatively discloses a computer vision-based UAV automatic landing guidance method, the method includes the following steps: In the first step, it is judged whether the UAV has reached a predetermined position, The predetermined position includes height information; in the second step, after it is determined that the predetermined position has been reached, an image heat map is generated using the image acquired by the camera on the drone; in the third step, the drone is identified based on the cascaded deep convolution model The position information of the ping, and the attitude information is generated based on the image heat map; in the fourth step, the UAV is guided to land automatically based on the position information and attitude information. The invention also innovatively introduces an auxiliary neural network for training relevant deep neural networks.

Description

technical field [0001] The invention belongs to the field of computer vision, in particular to a method for guiding the automatic landing of an unmanned aerial vehicle based on computer vision. Background technique [0002] In the prior art, the landing of the UAV is generally based on the manual control of the pilot or the deceleration and landing of a fixed program. The disadvantages of the automatic landing in the prior art are poor terrain applicability, large landing position deviation and mismatched landing attitude, resulting in large impact and unsafe landing. [0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention propos...
