Problems solved by technology

However, due to the small amount of radar data, it is highly dependent on the environment. For example, similar environmental characteristics or changes in environmental characteristics have a serious impact on the lidar-based navigation system, such as in a scene with too many similar environmental points, or In scenarios where the environment changes greatly, and in scenarios where there is a large flow of people, it is easy for the navigation system to fail to perform accurate and efficient navigation and positioning

Abstract

A navigation and positioning method of a robot comprises the following steps: establishing an image database, and obtaining corresponding relationships between coordinates and radar images and betweenthe coordinates and color images and/or depth images; detecting whether the matching degree of a current radar image and a radar image in an image database is less than a preset threshold value or not; if the acquired color image is less than the preset threshold value, starting a color image camera and/or a depth image camera, performing matching positioning on the acquired color image and the color image in the image database, and performing matching positioning on the acquired depth image and the depth image in the image database. Therefore, in the whole navigation and positioning process,the whole navigation and positioning precision can be improved, and the problem of robot positioning drifting can be effectively solved.

Description

technical field [0001] The present application belongs to the field of intelligent robots, and in particular relates to a robot and its navigation and positioning method and device. Background technique [0002] After the navigation technology is applied to the mobile robot, functions such as patrolling and tour guide can be realized, or the robot can automatically return to the charging position when the battery power of the robot is low. For example, in commercial scenarios, in order to realize the fully automatic workflow of the robot, it is necessary to perform automatic recharging when the power is lower than the set value. In the future, the robot will automatically start up and start working. [0003] In order to realize the function of automatic recharging, the navigation efficiency and accuracy of the robot's navigation function are very important. In order to realize the navigation function, the sensors generally used include: lidar, color camera, depth camera, e...
