全景环视辅助泊车系统的研究

随着城市道路越来越拥挤,驾驶员行车和停车的环境也日益复杂,能否为驾驶员提供车辆周围全方位的可视监控信息是提高行车安全性的关键。为此,对一种全景环视泊车辅助系统进行了研究,该系统包括1个中央控制器、1个显示器和分别安装在车辆前、后和两侧的4个广角摄像头。4个摄像头分别采集车辆前、后、左和右4个方向的图像信息,传送给中央控制器,经过摄像头参数校正、镜头扭曲校正、鸟瞰视角转换、白平衡匹配和图像缝合处理,最终在显示器上显示一个可直观监视车辆周围环境的全景鸟瞰画面。

Research on Around View Monitor System for Parking Assistance

With the urban roads more crowded and the environment of driving and parking for driver more complicated, whether the driver can be provided the visible surrounding information of vehicle is the critical factor for improving the driving security. Therefore, a around view monitor （AVM） system for parking assistance was researched. This AVM system was composed by a controller, a monitor and four wide-angle cameras which were mounted in front, rear and both sides respectively. The complete surrounding image information in front, back and sides of vehicle were collected by cameras and sent to the controller. After the processing in camera calibration, lens distortion correction, bird-view transformation, white balance match and images mosaic, a complete surrounding bird-view picture which could be used to monitor the surrounding condition clearly was displayed on the screen.
