Abstract

The invention discloses an AGV (Automated Guided Vehicle) positioning method, an AGV positioning device and an AGV positioning system. The method comprises the following steps: acquiring a to-be-identified first picture; performing regional treatment for the first picture, obtaining the first preset amount of regional pictures, and setting position mark information for each regional picture, wherein the position mark information is used for marking a position of the regional picture in the first picture; acquiring at least one regional picture as a to-be-contrasted regional picture; matching asample regional picture in a prestored sample picture with the to-be-contrasted regional picture, and obtaining a matching result, wherein the position of the sample regional picture used for executing matching and located in the sample picture is same as the position of the to-be-contrasted regional picture in the first picture; and according to the matching result, acquiring positioning information which is uniquely corresponding to the first picture and sending the positioning information to the AGV. According to the method, the device and the system provided by the invention, a problem offailure in recognition of the positioning information caused by damage of a part of the picture can be avoided, moreover, computation burden of picture contrasting is reduced, and picture recognitionspeed is improved.

Description

technical field [0001] The present disclosure relates to the technical field of image recognition, and more specifically, to an AGV positioning method, device and system. Background technique [0002] With the development of smart manufacturing, smart cars, such as AGV cars (Automated Guided Vehicle, automatic guided vehicle) are widely used in factories. The information acquisition of the AGV trolley requires the help of two-dimensional code recognition technology. [0003] Usually, a two-dimensional code picture is pasted at every preset distance on the preset route of the AGV car, and the two-dimensional code picture contains information required by the AGV car, such as positioning information. The AGV trolley scans and recognizes the QR code image to obtain the specified information contained in it, and performs corresponding operations according to the executed information. [0004] However, in the above-mentioned prior art, if the two-dimensional code picture is dama...
