Abstract

The invention discloses an AGV navigation positioning method for container loading, and belongs to the technical field of intelligent logistics. The method comprises the following steps: installing alaser radar on an AGV; automatically guiding a transport vehicle to walk along the central axis in the container and collecting point cloud data in the container by the laser radar in the walking process; autonomously extracting the linear features on the two sides of the container from the original point cloud data to calculate the distance from the laser radar to the left side surface and the right side surface of the container, obtain the distance deviation of the automatic guided transport vehicle deviating from the central axis of the container and obtain the angle deviation of the courseangle of the automatic guided trasnport vehicle and the central axis of the container through the slopes of the two linear features; and enabling the movement of the AGV to track a predetermined route according to the distance deviation and the angle deviation. Only one 2D laser radar is utilized to realize vehicle body navigation and positioning without additional auxiliary navigation sensor orlandmark, and the cost of automatic loading of the AGV in the container is greatly saved.

Description

technical field [0001] The invention relates to the technical field of intelligent logistics, in particular to an AGV navigation and positioning method for container loading. Background technique [0002] With the development of science and technology, the logistics industry has gradually moved towards the era of intelligence. In the intelligent logistics industry, AGV means "automatic guided transport vehicle" and has a wide range of applications. AGV refers to automatic guidance devices equipped with electromagnetic or optical. It is a transport vehicle that can drive along the specified guiding path, has safety protection and various transfer functions, and a transport vehicle that does not require a driver in industrial applications, and uses a rechargeable battery as its power source. Generally, the computer can be used to control its travel route and behavior, or use the electromagnetic track to set up its travel route. The electromagnetic track is pasted on the floor,...
