Embodiment Construction

[0062] In order to prevent collisions with obstacles during flight, the UAV uses obstacle detection technology. Obstacle detection technology obtains the depth map of the surrounding environment of the UAV, analyzes the depth information contained in the depth map, and judges the distance between the UAV and the obstacle in the direction of its moving speed, and then according to the distance between the moving object and the direction of its moving speed The distance of the obstacle is used to judge whether it is necessary to avoid the obstacle.

[0063] Since the obstacle detection technology needs to process the entire depth map when analyzing the depth information contained in the depth map, that is, each pixel of the depth map needs to be processed, so the computational complexity is relatively high. And because the chip processing capability of the UAV is limited, the use of this obstacle detection technology will not only consume a lot of chip resources, but also take a...

Abstract

The invention provides an obstacle detection method comprising the steps as follows: receiving a depth map in the moving direction of a moving object; determining a region of interest in the depth map, wherein the projection region of the moving object in the depth map is within the region of interest; acquiring the minimum depth value of the region of interest, and judging whether the minimum depth value of the region of interest is smaller than or equal to a depth threshold; and when the minimum depth value of the region of interest is smaller than or equal to the depth threshold, determining that there is an obstacle in the moving direction of the moving object. The invention further provides an obstacle detection system employing the obstacle detection method and a moving object. According to the obstacle detection method, the obstacle detection system and the moving body, whether there is an obstacle in the moving direction of the moving object can be judged accurately.

Description

technical field [0001] The invention relates to an obstacle detection method and system and a moving object. Background technique [0002] During the flight of the UAV, the operator needs to control the UAV to avoid obstacles in real time. When the flying speed of the UAV is fast, it is often difficult for the operator to judge the obstacles on the flight path in a short time, so that the UAV is easy to hit the obstacle and cause damage. Contents of the invention [0003] In view of the above, it is necessary to provide an obstacle detection method that enables a moving object to quickly and accurately determine whether there is an obstacle in its moving direction. [0004] It is also necessary to provide an obstacle detection system that enables a moving object to quickly and accurately judge whether there is an obstacle in its moving direction. [0005] It is also necessary to provide a moving object to which the obstacle detection system is applied. [0006] A method...
