Abstract

The invention discloses an obstacle visual detection system, and the system comprises a feature extraction module which is used for extracting feature points of an image; the feature matching module is used for matching feature points of the binocular camera image; and the obstacle area calculation module is used for calculating an obstacle blocking area.

Description

technical field [0001] The invention relates to visual detection technology, in particular to an obstacle visual detection system. Background technique [0002] In the research of the autonomous following robot system, whether the robot can accurately and quickly detect the obstacles in the process of moving becomes the key to the autonomous following robot system. Most robot systems use sonar to avoid obstacles, by actively transmitting detection signals, and then receiving echoes reflected by objects in the scene, and obtaining scene information by measuring the transmitted and returned signals. Sonar obstacle avoidance only has the characteristics of local space obstacle avoidance (it can only detect obstacles at a specific height and viewing angle, and the detection range and detection distance have relatively large limitations), and does not have the characteristics of detecting global vision. [0003] The other is a binocular stereo vision method, a 3D vision system i...
