Abstract:
A method of calibrating a multi-camera vision system includes moving a vehicle along a vehicle assembly line having targets at respective side regions, with each target including a longitudinal line and a plurality of tick marks that extend laterally from the longitudinal line. As the vehicle moves along the vehicle assembly line it is equipped with a plurality of cameras and an image processor. As the vehicle moves along the vehicle assembly line, the target at a respective side region of the vehicle assembly line is present within the fields of view of front, side and rear cameras. Image data is captured by the cameras and processed to detect the targets and to determine misalignment of at least one of the cameras. The vehicular multi-camera vision system is calibrated by adjusting processing by the image processor of image data captured by the at least one misaligned camera.
