The invention provides a positioning identifier, a robot for identifying the positioning identifier and a positioning method executed by the robot. The robot firstly obtains a target image including the positioning identifier, the positioning identifier comprises a two-dimensional code and at least two positioning markers arranged on the periphery of the two-dimensional code, and then the robot determines a central position and a rotation angle of the two-dimensional code in the target image based on the at least two positioning markers.. According to the technical scheme, the central position and the rotation angle of the two-dimensional code in the target image are determined based on the position information of the positioning markers in the target image and the preset position of each positioning marker relative to the two-dimensional code, so that the positioning accuracy of the two-dimensional code can be effectively improved, and the analysis and utilization efficiency of the two-dimensional code can be improved.
Description
technical field [0001] The present application relates to the fields of computer technology and image processing, and specifically relates to a positioning mark, a robot for recognizing the positioning mark, and a positioning method performed by the robot. Background technique [0002] Since the two-dimensional code can flexibly include various information, the two-dimensional code is more and more widely used. When the robot uses the QR code, it needs to analyze the QR code. The premise of analyzing the two-dimensional code is to locate the two-dimensional code in the image. Only when the exact position of the two-dimensional code is determined can the two-dimensional code be successfully parsed. Quickly and accurately locate the position of the two-dimensional code, which can improve the processing speed of the two-dimensional code analysis. [0003] During the process of positioning the two-dimensional code, due to the interference of other objects, the robot may not be...
