In recent years, large-scale transport vehicles such as tank trucks and gravel vehicles have frequently observed that there is a visual dead angle of a person in the vehicle body due to driving, resulting in a frequent death of the cockroach; and installed in the large-scale transport vehicle. Most of the cameras are installed on the front and rear sides of the car body, focusing on the warning when reversing. The camera is not installed on the left and right sides of the car body, and the camera lens cannot adjust the angle, but it is prone to collision accidents. The situation usually occurs during the march. Many of them are due to the design of the car body, which causes a dead angle on one side. When driving on the road in the past, there are often some roadside ravines or dead corners that are difficult to see. It is impossible to actually know the distance between the two cars. It is often because the distance is not visible, causing traffic jams. When reversing, the blind spots that are not visible in the right front are often the cause of collisions. If the sky is dim, the image becomes quite Blurring, at this time, the safety of reversing is reduced, which increases the possibility that the parking situation will occur.

On the other hand, even if the vehicle body is equipped with a camera at each position where a visual dead angle may be generated and the image area captured by the cameras can be displayed on the monitor screen, the display screen currently used for monitoring in the vehicle body is used. Most of them are between 7 and 9 inches. Because of the configuration of multiple cameras, they are monitored on multiple cut screens of the screen. Most of the monitor screens are cut into 9 equal parts, and are divided into such a small screen. A plurality of cut screens result in a display area of each cut screen, and the driver can clearly observe that the live image in the shooting area is not clear enough, and when the sky is dark, the image becomes more blurred, causing an accident, so There are still many unsatisfactory aspects of knowing technology and it needs to be improved.
