Abstract

The invention relates to the technical field of mobile robot indoor positioning, in particular to an indoor positioning system and method for a mobile robot based on multiple depth cameras. The system comprises a central control unit and a robot control unit, wherein the central control unit is used for determining the position of the robot and sending the position to the robot control unit, and the robot control unit is used for controlling the robot to act according to positioning information sent by the central control unit. The method is realized based on the system. According to the invention, indoor positioning of the mobile robot can be better realized.

Description

technical field [0001] The invention relates to the technical field of indoor positioning of a mobile robot, in particular to an indoor positioning system and method for a mobile robot based on a multi-depth camera. Background technique [0002] Positioning technology is a key technology in the research of mobile robots. For an autonomous robot system, accurate spatial positioning is the prerequisite for its autonomous navigation. There are currently many methods to obtain the position information of the robot, which are mainly divided into the following two categories: ①Record the robot’s own movement process through sensors such as code discs, electronic gyroscopes, and accelerometers, and calculate the current position through cumulative calculations; ②Use radar, laser rangefinder, image matching, etc. to determine the relative position of the robot and the environment to obtain its own location information. The existing mobile robot positioning technology usually has la...
