Description

Technical Field

[0001] This utility model relates to the field of license plate recognition equipment technology, and in particular to a smart community license plate recognition equipment. Background Technology

[0002] Community license plate recognition equipment is an intelligent system used to identify and manage vehicles entering a community. It is mainly used at community entrances and exits, and automatically records vehicle information through license plate recognition technology to achieve automatic vehicle management and control.

[0003] Existing community license plate recognition devices mostly rely on a single vision sensor, which is easily affected by environmental factors such as lighting, rain, and snow, leading to a decrease in recognition rate. In addition, traditional devices lack dynamic adjustment capabilities, and the barrier structure is fixed, making it difficult to adapt to different vehicle models or scenarios where abnormal vehicles enter.

[0004] While some devices are equipped with radar or temperature and humidity sensors, they mostly operate independently and lack multi-sensor data fusion, resulting in insufficient intelligence. Therefore, there is an urgent need for a license plate recognition device that integrates multimodal perception and has adaptive adjustment capabilities to improve environmental adaptability and control accuracy.
