Description

Photographic display control system

This creation department is concerned with traffic monitoring, especially a photographic development control system that is simple in structure, wide in applicability, and capable of actively adjusting and displaying an expected visual dead zone according to the driving state.

Driving safety has always been the first priority of traffic safety. For the driver, there is inevitably an invisible visual dead zone when driving, especially large vehicles such as buses, large trucks, gravel cars, and even containers. Large vehicles such as cars and connecting cars have many dead angles due to their high driving seats and long body. There are many dead angles on the side and rear. Because of their heavy weight, long wheelbase and large radius of gyration, it is difficult to get the car during driving. The body responds immediately, so traffic accidents caused by visual dead ends are endless, often causing irreparable damage.

There are a variety of surveillance systems that use side or rear cameras to assist the driver in observing the dead angle. However, there are different needs due to the changing conditions between the travels, and the conventional products are difficult to meet the needs of use; for example, When the connecting vehicle turns, the relative angle of the car body changes, which causes the camera on the side to not capture the dead angle area that needs to be observed when turning, or the camera that is placed behind the car body. Observe the condition or obstacle behind the car body, but because the shooting angle is limited, it is difficult to provide the driver with the distance when reversing. Information; although the above situation can be improved by using multiple photographic lenses or wide-angle photographic lenses with sufficient angle of shooting, multi-lens will inevitably increase the cost of equipment and installation, and too many display screens are not good for drivers. For observation, in addition, if the wide-angle image with too large a range is displayed on the display screen, the proportion of the dead angle area to be observed in the picture is too small, which is also unfavorable for the driver to observe while driving.

In addition, these known auxiliary photographic devices, due to the limitations of the original car body or other factors, must be installed to avoid damage to the car body, so the photographic lens is installed in a position such as a rear view mirror. Although there is a way to track the dead zone by using a rotating camera lens, it is based on the change of driving conditions, but it is based on the design of the rotating lens, waterproofing, control, etc., as well as the installation and wiring of the car body structure. It will cost uncommonly, and it is difficult to apply it to a wide variety of vehicle types.

In view of this, how to find a monitoring device or mode that can be widely applied to a driver in the case of meeting installation and cost considerations is a problem that has been to be improved in the art.

The present invention provides a photographic development control system whose main purpose is to save costs and meet installation requirements by a small amount of equipment, and can be widely applied to various vehicle carriers, and actively driven according to a simple control mechanism.
