Abstract

The invention discloses an object detecting method and system based on stereoscopic vision. The method includes acquiring a foreground depth image extracted from a stereoscopic depth image; and setting a height threshold value for obtaining a block, whose value is greater than the height threshold value, in the foreground depth image. If the obtained block meets a predetermined single object condition, the obtained block is detected as a block with a single object. If the obtained block meets a predetermined multi-object condition, smaller blocks with the objects in the obtained block are detected as the blocks with the single objects. If the obtained block does not meet the predetermined single object condition or the predetermined multi-object condition, the height threshold value is changed until the obtained block meets the predetermined single object condition or the predetermined multi-object condition.

Description

technical field [0001] The present disclosure relates to the field of stereo vision image processing, and more particularly, to object detection technology based on stereo vision. Background technique [0002] The detection and tracking of objects such as people is based on technologies such as human-centered computing, and active services can be provided and pushed only after people are accurately positioned. Target positioning such as people is to obtain the indoor or outdoor position information of the target, that is, to obtain the coordinate values ​​(x, y, z) of the target in the world coordinate system. [0003] The correctness of detection of objects such as people is a fundamental problem of localization of objects such as people. At present, it is still a challenging technical subject. The introduction of 3D vision has greatly improved the solution to this problem. 3D vision includes not only the red, green, blue (RGB) color information of the image, but also th...
