License plate recognition is a pattern recognition technology that uses the dynamic video or static image of the vehicle to automatically recognize the license plate number and the color of the license plate. The core of the technology includes license plate location algorithm, license plate character segmentation algorithm and optical character recognition algorithm. The working principle of license plate recognition technology Vehicle detection: Buried coil detection, infrared detection, radar detection technology, video detection and other methods can be used to sense the passing of the vehicle and trigger image capture. Image collection: Real-time and uninterrupted recording and collection of passing vehicles through the high-definition camera capture host. Preprocessing: noise filtering, automatic white balance, automatic exposure and gamma correction, edge enhancement, contrast adjustment, etc. License plate location: Scan the rows and columns on
