Abstract

The invention provides a vehicle positioning system and positioning method based on a two-dimensional code, and the system comprises an image collection device, a positioning controller, and a positioning two-dimensional code disposed on a track. The image acquisition device is connected with the positioning controller. The image acquisition device is used for carrying out image acquisition on thepositioning two-dimensional code to obtain a two-dimensional code image and sending the two-dimensional code image to the positioning controller; and the positioning controller is used for receivingthe two-dimensional code image and analyzing the two-dimensional code image to obtain the position of the positioning two-dimensional code, and taking the position of the positioning two-dimensional code as the current position of the vehicle. By means of the system, vehicle positioning can be achieved according to the positioning two-dimensional code on the track, omnibearing reading is achieved.The vehicle positioning accuracy and the environment adaptability and fault-tolerant capability of the positioning system are improved, and the technical problems that in the prior art. The environment adaptability is poor, and the positioning accuracy is low are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a two-dimensional code-based vehicle positioning system and positioning method. Background technique [0002] The existing vehicle positioning methods mainly include vehicle positioning technology based on query transponders, positioning technology based on radio frequency identification cards and radio frequency identification readers, and positioning technology based on bar bar location codes. [0003] The vehicle positioning technology based on query transponders can only provide point-based positioning information. Due to the contradiction between setting distance and investment scale, using the transponder positioning method has a huge investment cost per kilometer; and the transponder's strict requirements for non-metallic areas reduce In addition, when the locomotive loses the position of the transponder or the locomotive receives the transponder information during...
