Abstract

The present invention provides an image processing method, comprising: acquiring two real-time images taken by two camera devices, determining a disparity map according to the two real-time images; respectively determining the weak texture regions of the two real-time images according to preset weak texture determination rules Information; remove the weak texture region in the disparity map according to the weak texture region information in the two real-time images. The present invention builds a three-dimensional map based on the disparity map that removes the weak texture area, so that the established three-dimensional map is more accurate, and avoids the wrong matching of weak texture areas such as sky, water surface, and white wall, and the interference of noise on the establishment of the three-dimensional map. It is convenient for the UAV to realize accurate obstacle avoidance through the three-dimensional map, improve the service life of the UAV, and reduce the damage rate of the UAV.

Description

technical field [0001] The present invention relates to the fields of image processing, three-dimensional reconstruction and aircraft, and in particular, the present invention relates to an image processing method, device and mobile device control method. Background technique [0002] At present, with the continuous development of UAVs, UAVs have been used in agriculture, aerial photography, aerial surveying, etc. However, UAVs need to identify obstacles that hinder UAVs from flying during the flight process to ensure that UAVs In the prior art, a three-dimensional map can be established by taking an image and performing three-dimensional reconstruction based on the taken image. According to the three-dimensional map, the UAV's route can be more clearly and accurately identified. In the process of UAV flight, weak texture areas such as sky, water surface, white walls, etc. will lead to wrong matching and wrong depth of field recovery, and the captured images are often digiti...
