    • An image processing unit determines the size of a circumscribed quadrangle of the target object, and predicts the overlap of the two different objects. If overlap is predicted, the target object is divided into two divided regions L_b and R_b containing the left and right edges of the target object respectively, and by performing a correlation calculation between the left image and the right image captured by a stereo camera for each of the divided regions, the parallaxes of the respective divided regions L_b and R_b can be determined. Then, if the absolute value of the difference between the parallaxes of the respective divided regions L_b and R_b is greater than a predetermined value, a determination is made that different objects are overlapping within the target object, and the target object is divided for recognition, and the distance to the respective objects is calculated independently.
    • 图像处理单元确定目标对象的外接四边形的大小,并且预测两个不同对象的重叠。 如果预测重叠,则将目标对象分别分别包含目标对象的左边缘和右边缘的两个分割区域L_b和R_b,并且通过对于每个对象物体执行由立体相机拍摄的左图像和右图像之间的相关计算 可以确定各分割区域L_b,R_b的视差。 然后,如果各个分割区域L_b和R_b的视差之间的差的绝对值大于预定值,则确定不同对象在目标对象内重叠,并且目标对象被划分以进行识别, 并且独立地计算到各个对象的距离。
