Problems solved by technology

[0004] However, the current method has great disadvantages, for example: only when the center of the car body is the center of motion, the calculated result is more calibrated; If there is a problem in one aspect, the error of the result will be relatively large, but in actual operation, errors in these two aspects are unavoidable; the operation steps are complicated and it takes a long time

Abstract

The invention discloses a double-laser scanner calibration method, device and equipment. The method comprises the following steps: establishing a differential motion model; controlling the vehicle body to walk a set route according to the differential vehicle motion model; acquiring motion route data of a vehicle body and positioning data of a laser; calculating the deviation between the laser andthe vehicle body motion center; and calibrating the double-laser scanner according to the calculated deviation value. According to the invention, result errors caused by manual misoperation are reduced; and the influence of the vehicle body machining error on the calibration result is reduced.

Description

technical field [0001] The invention relates to a dual laser scanner calibration method, device and equipment, belonging to the technical field of scanner calibration. Background technique [0002] AGV control needs to be controlled according to the position of the center of motion of the AGV, which requires the positioning part to transfer the positioning point of the laser to the positioning point of the center of the car body. This transfer process requires the position deviation of the laser relative to the center of the car body. For AGVs with dual lasers or multiple lasers, it is necessary to ensure that the positioning results of each laser can be transferred to the center of the car body, and the coordinates of all lasers after transfer are basically the same. [0003] At present, the method of determining the position deviation of the laser relative to the center of the car body is generally to attach four long boards to the surroundings of the car to surround the l...
