Sorting robot target positioning system based on computer vision and RFID

The invention discloses a target cargo grabbing method based on RIFD and computer vision, and belongs to the technical field of cargo grabbing methods. The system comprises a data processing module, a coarse-grained space region positioning module and a fine-grained space coordinate positioning module. The data processing module comprises an RFID data processing module and a computer vision module; the coarse-grained space region positioning module is used for positioning a goods shelf where a target article is located based on a label azimuth measurement algorithm for scanning along a circular trajectory and a label positioning algorithm of a block hologram; and the fine-grained space coordinate positioning module is used for positioning the accurate coordinate position of the target object relative to the robot based on a sequence matching fusion mode. According to the method, the latest progress of the RFID technology and the computer vision technology is combined, efficient and accurate target article pos
