Problems solved by technology

Starting from the origin such as the charging position, the robot relies on the rotation of the motor to trigger the signal output by the encoder to measure the walking distance. However, when the robot runs a certain distance, it will generate a cumulative error by relying on the encoder to count, which will cause the encoder of the inspection device to perform positioning. There is a deviation in the position data, so the robot that usually runs on the track needs to perform position calibration after running for a certain distance

Abstract

The invention relates to a position calibration system and method and a computer readable storage medium, and relates to the technical field of computers. The position calibration system includes: anoptical label including a plurality of uneven constituent units; the inspection device which comprises a plurality of optical distance sensors and is configured to measure a plurality of distances from a plurality of uneven composition units on the optical label to the inspection device; and a processor configured to: acquire the plurality of distances from the plurality of optical distance sensors; determining standard position data of the position of the optical label according to the change rule of the plurality of distances; and performing position calibration on the inspection device by using the standard position data, the inspection device being located at a position corresponding to the optical label on an inspection track. According to the invention, the computing resource consumption of the inspection device is reduced, and the accuracy of position calibration is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular to a position calibration system and method, and a computer storage medium. Background technique [0002] The inspection device used to perform inspection tasks in the tunnel relies on the track to perform inspection tasks in the tunnel. Starting from the origin such as the charging position, the robot relies on the rotation of the motor to trigger the signal output by the encoder to measure the walking distance. However, when the robot runs a certain distance, it will generate a cumulative error by relying on the encoder to count, which will cause the encoder of the inspection device to perform positioning. There is a deviation in the position data of the robot, so the robot that usually runs on the track needs to perform position calibration after running for a certain distance. [0003] In the related technology, the inspection device uses an RFID (Radio Frequency Ide...
