Abstract

The invention relates to an indoor AGV self-adaptive positioning method based on laser SLAM, and relates to the technical field of positioning of fusion of multiple sensors of laser SLAM, odometer and IMU. The indoor AGV adaptive positioning system includes an upper computer, a lower computer, a motor drive device, a 2D laser radar, an odometer and an inertial measurement unit. Using lidar to build a two-dimensional grid map of the AGV's working environment, according to the different structural features in the working environment, adaptively switch between the ICP matching algorithm based on feature points and the matching algorithm based on optimization, so as to improve the AGV in The realization of positioning accuracy and speed in a complex working environment can effectively overcome the problems of low positioning accuracy, poor positioning flexibility and high cost of AGV existing in the prior art.

Description

technical field

[0001] The invention relates to the technical field of robot positioning, in particular to a laser SLAM positioning method for self-adaptive switching of multi-sensor fusion of 2D laser radar, odometer and inertial measurement unit. Background technique

[0002] With the rapid development of society, more and more people shop online in recent years, making the logistics industry develop in a more intelligent and efficient direction. Automated Guided Vehicle (AGV) is a vehicle that automatically travels along a specified path in a working environment, and is usually used for the transportation of industrial production or warehouse goods. It is one of the most widely used robots in the logistics industry. AGV is playing an increasingly important role in modern industrial production and has been widely used.

[0003] As a small car with autonomous positioning and navigation functions, AGV is a complex system integrating environmental perception, path planning,...
