Abstract

The invention provides a robot navigation device and system based on stereoscopic vision matching. The system is composed of a stereoscopic vision module, a stereoscopic matching module, an obstacle detection module, a target detection and tracking module, a target positioning and presetting module, a data fusion module, and a positioning and navigation module. According to the invention, detection of an obstacle area is realized by using a 3D disparity map, target object detection is carried out by using the 2D image and the 3D disparity map, and then a safety path of passing of a robot is selected based on the location information of the target and obstacle. Accuracy of segment is ensured by combining the characteristic of quick identification of the 2D image scene and the 3D depth information.

Description

technical field [0001] The invention relates to the technical field of robot navigation, in particular to a robot navigation device and system based on stereo vision matching. Background technique [0002] Intelligent robot navigation technology refers to the effective acquisition of information about the environment and its own position and posture through the sensors carried by itself, and at the same time complete the detection of obstacles and targets in the environment, and autonomously plan the path from the starting position to the target position, so as to realize the goal. object to operate. It has complete perception, analysis, decision-making and execution modules, and can independently engage in production activities in the environment like humans. [0003] Most of the existing robot navigation systems use sonar to avoid obstacles, by actively transmitting detection signals, and then receiving the echoes reflected by various objects in the scene, and obtaining s...
