Abstract

The invention provides a robot mapping method and device, a robot and a storage medium. The method comprises the steps that point cloud data obtained through laser radar scanning, positioning data, obtained through a positioning module, of a robot and posture data, obtained through an inertia measurement unit, of the robot are obtained; actual coordinates of each laser point in the point cloud data are obtained based on the positioning data and the posture data; and a first map is generated based on the actual coordinates of each laser point in the point cloud data. According to the robot mapping method provided by the embodiment of the invention, loopback detection is not needed. Besides, the position data of the robot and the posture data of the robot are obtained through the positioningmodule and the inertial measurement unit respectively; compared with the robot position data and posture data reversely determined through the point cloud data, so that the constructed map is more accurate, and the laser mapping mode can be suitable for the outdoor strong light environment.

Description

technical field [0001] The present application relates to the technical field of robots, and in particular, relates to a robot mapping method and device, a robot and a storage medium. Background technique [0002] At present, there are many methods for robots to build maps. SLAM (Simultaneous Localization And Mapping, real-time positioning and map construction) is the most commonly used method. The positioning of its own position and attitude and the system of scene map information. At present, the most common SLAM is laser SLAM. The core of laser SLAM is to match and compare two pieces of point cloud data obtained by laser radar scanning at different times, and calculate the relative motion distance and attitude change of laser radar to realize the positioning of the robot itself, and then complete the positioning and map. Construct. However, this method has the following disadvantages: 1. In a strong light environment, the positioning data of the robot obtained through ...
