针对城市道路监控的需求,提出了一种基于感兴趣区域的摄像机自适应控制方法.它作为车牌识别系统的一个辅助功能,在固定光圈的情况下,能够根据车牌识别和运动检测的反馈信息自适应地调节摄像机的快门和增益,获取较好质量的图片,从而达到提高车牌识别率的作用,特别是该方法能够大大降低强逆光和强眩光现象对采集图像质量的影响.

Camera control is necessary in a typical intelligent transportation system.An adaptive control method of camera based on ROI(region of interested) is brought forward.It changes shutter and gain of the camera a- daptively with the feedback from license plate recognition and motion detection, then more high quality images can been captured to improve license plate recognition.Especially, it can greatly reduce the influence of back-lighting and glare.
