Robot autonomous navigation system

Abstract

The invention provides a robot autonomous navigation system, which includes a dual-laser-radar ranging module, an image acquisition module, a data fusion analysis module and a route planning module. The dual-laser-radar ranging module includes two laser radars set at different heights, and is used for detecting obstacle information in two planes at different heights. The image acquisition module is used for acquiring image information in front of a robot. The data fusion analysis module and the route planning module generate a 3D virtual map according to the obstacle information in two planesat different heights and the image information, and further generate obstacle avoidance information. The route planning module plans a moving route according to the obstacle avoidance information. Byusing the two laser radars at different heights and the image acquisition module, the robot autonomous navigation system can fully collect obstacle information around a robot, generate a 3D virtual map, and realize accurate and autonomous navigation of the robot based on the 3D virtual map.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence and automation, and more specifically, to a robot autonomous navigation system. Background technique [0002] With the rapid development of sensor technology, artificial intelligence theory, and computer technology, the field of robotics has been in-depth research, and various autonomous mobile robots with environmental perception capabilities, behavior control, dynamic decision-making capabilities, and human-computer interaction capabilities have been developed. Compared with traditional industrial robots, the biggest feature of autonomous mobile robots is that they can move freely in complex environments to perform various tasks. [0003] The working environment of autonomous mobile robots has gradually developed from indoor environments to outdoors, sky, underwater and even planets beyond the earth. However, among the many technologies of mobile robots, the most importa...

Problems solved by technology

Although the well-known GPS navigation has been gradually used in people's daily life, for mobile robots that require very fine detail, GPS cannot provide the accuracy and error that meet the requirements.

[0004] Although there are already many types of indoor mobile robots, and navigation systems with radar or visual sensors for obstacle detection are mostly used, there are certain deficiencies in the detection devices in the current navigation systems; The detection device cannot obtain accurate depth information; the detection device composed of dual lidar sensors can only obtain obstacle information in two planes in space, resulting in incomplete obstacle information around the robot detected by the detection device; and a The detection device composed of a visual sensor and a laser radar has limited ability to obtain information about obstacles around the robot; therefore, the detection device in the current navigation system detects limited obstacle information around the robot, which affects the navigation accuracy of the navigation system for the robot.
