A recently granted patent (Publication Number: US11881039B2) discloses a license plate recognition (LPR) system designed for law enforcement vehicles. The system includes a camera device capable of capturing long-exposure and short-exposure images simultaneously, a memory for storing images, and a processor programmed to detect license plates in both types of images. By analyzing motion blur and adjusting exposure settings, the system aims to enhance the recognition of characters on license plates, particularly in short-exposure images where recognition probability is higher. Additionally, the system can merge multiple images to create a consolidated image for improved recognition accuracy by a computerized optical character recognition platform.

Furthermore, the patent details a method and a tangible non-transitory computer-readable medium storing executable instructions for the LPR system. The method involves steps such as adjusting exposure settings, detecting license plates in different images, aligning and transforming images for accurate recognition, and merging images into a consolidated format. The computer-readable medium contains instructions for adjusting exposure settings, capturing images simultaneously in serial or parallel manners, and enhancing character recognition through consolidated image creation. By utilizing these innovative techniques, the LPR system aims to improve the efficiency and accuracy of license plate recognition for law enforcement purposes, ultimately enhancing surveillance and security measures on the road.
