Problems solved by technology

[0003] When the AGV is damaged due to the color track, the AGV needs to make a large rotation in situ, move forward and backward to translate the vehicle, etc. to re-find the landmarks on the ground, and it will take a long time and the correction efficiency is low.

Abstract

The invention relates to the technical field of AGV navigation, in particular to a correction method and correction system for a double-steering-wheel AGV based on a color track and two-dimensional code navigaby.The correction method comprises the steps that deviation information is obtained, specifically, the deviation information between the AGV and a preset path is obtained; and standardization of the deviation information: processing and converting the deviation information to form standardized deviation information. According to the method, the deviation angle and distance of an AGV relative path are collected in real time through a visual sensor, the rudder angle, speed and rotating speed information of the AGV is output in real time through a double-steering-wheel motion model, and steering wheel angle and speed output is carried out through a double-steering-wheel motion model. The stable operation of the AGV with different steering wheel installation modes is ensured on the occasion that a color track is damaged and lost.

Description

Technical field [0001] The present invention relates to the field of AGV trail navigation technology, in particular, is a correction method of a two-rudder wheel AGV based on a color track and a two-dimensional code navigation and its correction system. Background technique [0002] Automatic Guide Cars (AGV) is an unmanned automatic vehicle that is dynamic and automatically guided by a charging battery. It can accurately walk and stop to the specified location under the monitoring of the computer. Complete a series of job tasks such as picking up, delivery, charging, etc. With the improvement of industrial automation and the rapid development of computer technology, AGV has more and more handling tools between assembly lines or operation equipment. In the prior art, the AGV navigation method is mainly divided into the following: electromagnetic navigation, optical navigation, tape navigation, laser navigation, ultrasonic navigation, inertial navigation, and image recognition nav...
