Qingdao license plate recognition (LPR) is a pattern recognition technology that uses dynamic or static images of vehicles to automatically recognize license plate number and color. LPR is a pattern recognition technology that uses dynamic or static images of vehicles to automatically recognize license plate number and color. Through image acquisition and processing, the automatic license plate recognition function can be completed. The license plate image can be automatically extracted from an image, the characters can be automatically segmented, and then the characters can be recognized. Its hardware basis generally includes trigger equipment (monitoring whether the vehicle enters the field of vision), camera equipment, lighting equipment, image acquisition equipment, license plate number recognition processor (such as computer), etc. The software core includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm.
