    • In conventional systems using an onboard camera disposed rearward of a vehicle for recognizing an object surrounding the vehicle, the object is recognized by the camera disposed rearward of the vehicle. In the image recognized by the camera, a road surface marking taken by the camera appears at a lower end of a screen of the image, which makes it difficult to predict a specific position in the screen from which the road surface marking appears. Further, an angle of depression of the camera is large, and it is a short period of time to acquire the object. Therefore, it is difficult to improve a recognition rate and to reduce false recognition. Results of recognition (type, position, angle, recognition time) made by a camera disposed forward of the vehicle, are used to predict a specific timing and a specific position of a field of view of a camera disposed rearward of the vehicle, at which the object appears. Parameters of recognition logic of the rearwardly disposed camera and processing timing are then optimally adjusted. Further, luminance information of the image from the forwardly disposed camera is used to predict possible changes to be made in luminance of the field of view of the rearwardly disposed camera. Gain and exposure time of the rearwardly disposed camera are then adjusted.
    • 在使用设置在车辆后方的车载照相机以识别车辆周围的物体的常规系统中,物体被设置在车辆后方的照相机识别。 在由相机识别的图像中,由相机拍摄的路面标记出现在图像的屏幕的下端,这使得难以预测出现路面标记的屏幕中的特定位置。 此外,相机的下压角度大,获取物体的时间短。 因此,难以提高识别率并减少错误识别。 使用布置在车辆前方的相机进行的识别(类型,位置,角度,识别时间)的结果用于预测设置在车辆后方的相机的视场的具体定时和特定位置, 该对象出现。 然后,最佳地调整后置摄像机的识别逻辑和处理定时的参数。 此外,来自前方照相机的图像的亮度信息用于预测在向后设置的相机的视场的亮度可能发生的变化。 然后调整向后放置的相机的增益和曝光时间。
