Abstract

The invention relates to the technical field of AGV positioning. The invention relates to a positioning method, in particular to a positioning method integrating laser SLAM and two-dimensional code navigation and a carrying platform. A laser SLAM navigation system is used for enabling a carrying platform vehicle body to move to a two-dimensional code marking position near a terminal point througha driving mechanism; the two-dimensional code scanner scans the two-dimensional code; the ID information of the two-dimensional code is obtained, and the accurate pose deviation of the carrying platform vehicle body is calculated through the vehicle control unit assembly; then the process enters a secondary positioning state, wherein an originally used global coordinate is changed into a relativecoordinate of a two-dimensional code coordinate system; the vehicle control unit assembly plans a feasible curve path according to the starting point coordinates and the corner point coordinates of the carrying platform vehicle body, and the carrying platform vehicle body is driven by the rear servo steering wheel assembly and the front servo steering wheel assembly to smoothly move to the terminal point. According to the technical scheme, the defects that in the prior art, AGV parking precision is low, the structure is complex, and cost is high can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of AGV positioning, in particular to a positioning method and a transport platform that integrate laser SLAM and two-dimensional code navigation. Background technique [0002] In recent years, with the development of science and technology, automation technology has shown a trend of accelerated development, and domestic automated three-dimensional warehouses and automated flexible assembly lines have entered the stage of development and popularization. Among them, AGV (Automated Guided Vehicle) plays an irreplaceable important role between the automatic warehouse and the production workshop, and between each station. [0003] At present, the AGV system has been widely used in the flexible handling system of industrial materials. With the rapid development of the logistics system, the application range of the AGV is also expanding. Simultaneous Localization and Mapping (SLAM) technology refers to placing the...
