Find out how the license plate recognition camera works.

License plate recognition technology refers to the technology of automatically reading license plate number, license plate type, license plate color and other information after machine vision, image processing and pattern recognition of vehicle images or video sequences shot by cameras, and is an important branch of artificial intelligence technology. Its hardware foundation includes trigger device, camera device, lighting device, image acquisition device and license plate recognition processor. Its software core includes algorithms such as license plate location, character segmentation and character recognition.

Working principle: image acquisition-preprocessing-license plate location-license plate correction-character segmentation-character recognition-recognition result output.
