    • The vehicle surroundings monitor detects the sizes and positions of obstacles, ditches and humans as well as the depths of the ditches to provide the driver with sufficient information to secure safety during driving. The pattern light projector receives an incoming laser beam and projects a light spot matrix in the form of a regular grating onto the monitored area. The camera photographs the light spot pattern on the monitored area and sends image signals to the data processor which processes the image signals to detect the presence of any obstacle, ditch or human. Based on the steering angle detected by the steering angle sensor, the path the car will take is predicted and a possible contact or collision of the car with the obstacle is detected beforehand. The buzzer, voice synthesizer and display device are used to alert the driver and indicate the presence of the obstacles, the possible contact with them and the location where the possible contact will occur.
    • 车辆环境监视器检测障碍物,沟渠和人类的大小和位置以及沟渠的深度,以向驾驶员提供足够的信息以确保驾驶期间的安全。 图案光投影仪接收输入的激光束并将普通光栅形式的光点矩阵投射到监视区域上。 相机拍摄被监视区域上的光点图案,并将图像信号发送到处理图像信号的数据处理器,以检测是否存在任何障碍物,沟渠或人类。 基于由转向角传感器检测到的转向角度,预测轿厢将采取的路径,并且预先检测到轿厢与障碍物的可能的接触或碰撞。 蜂鸣器,语音合成器和显示设备用于警告驾驶员并指示障碍物的存在,可能的接触以及可能发生接触的位置。
