车牌识别需解决的技术难点
Technical difficulties in license plate recognition
1、算法难点：汽车牌照区域定位、变形校正、旋转校正、污损修复、字符切分、字符识别。
1. Algorithm difficulties: license plate area positioning, deformation correction, rotation correction, stain repair, character segmentation, character recognition.
2、成像环节难点：环境光影响(太阳定向反射、镜面反射)、车辆高速运动中成像。
2. Difficulties in imaging: impact of ambient light (Sun directional reflection, mirror reflection), imaging in high-speed vehicle movement.
3、系统运行难点：全天候连续工作、系统无故障时间。
3. Difficulties in system operation: continuous operation all day long and no failure time of the system.
