However, due to the large size of the commercial vehicles in the longitudinal direction, the camera lens cannot collect all the images of the whole vehicle within the scope of the inspection line workshop due to the limited viewing angle. It can be measured by means of image stitching, but the measurement accuracy of image stitching is low, it takes a long time, and it cannot adapt to the detection beat of the detection line. In addition, the existing visual distribution uses a horizontal camera to collect a single image. On the one hand, a single image cannot obtain information on the three-dimensional scale direction. On the other hand, due to the limited space of the inspection workshop, the distance between the horizontal position of the camera and the operating vehicle does not exceed 1.5m , resulting in large distortion of the overall image collected at close range, and the image distortion corresponding to the position of the front and rear of the vehicle, which is critical to the measurement of vehicle length in a single image, is greatly distorted. From the perspective of improving measurement accuracy, it is necessary to use a double Therefore, the design of a top-mounted commercial vehicle-sized binocular panoramic vision inspection system is of great significance to the technological progress of the automotive industry inspection field.
