Description
Technical Field
The utility model belongs to the technical field of car safety assists and specifically relates to a van rear portion field of vision auxiliary system is related to.
Background
When a traditional automobile is designed, a driver can be guaranteed to see the front view through glass preferentially, and meanwhile, the proportion of cab components is attractive, and the like, so that the appearance of the interior rearview mirror tends to be small in size. In this case, the mirror surface reflection area of the rearview mirror is limited, and is easily limited by the viewing angle width of the C-pillar or D-pillar on both sides of the rear section of the automobile, and the width of the field of view of the driver viewing the rear of the automobile is affected by the blocking of the passenger in the rear row of the automobile, the headrest of the rear seat, the rear bumper, the rear body of the rear-box enclosed type, or the like. Secondly, when the automobile runs in bad weather such as rain, snow, fog, dust, and the like, the rear windshield is easy to accumulate water, fog, dust, and the like, and the situation that a driver watches the rear view of the automobile through the inside rearview mirror is rapidly influenced. When the automobile runs on a road without street lamps at low level at night, the rear view of the automobile cannot be viewed through the rearview mirrors when no light source exists behind the automobile, and when the automobile follows behind the automobile, the judgment of the direction, the distance and the shape of the automobile or other objects in the rear view by a driver can be influenced by the strong light irradiation of the rear headlights.

Fig. 1 is a schematic block circuit diagram of the present invention.
Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1, the vision auxiliary system at the rear of the van of the present invention includes a camera unit, a display unit and a control unit; the camera shooting unit comprises a wide-angle night vision high-definition camera arranged at the tail part of the vehicle; the display unit is a touch liquid crystal display screen arranged on the inside rearview mirror; the control unit includes: the system comprises a data conversion module, an MCU, a CPU and a photosensitive sensor;
the camera shooting unit collects video information and transmits the data information to the data conversion module;
the data conversion module receives data information, processes the data information and sends the processed data information to the CPU;
the CPU receives and processes the data information, and sends data to the display unit to display the video image in real time;
the photosensitive sensor collects ambient light information and sends data information to the MCU;
the MCU receives data information and sends the information to the CPU, and the CPU controls the display unit to adjust the brightness in real time; the camera unit also comprises a front-view camera arranged at the front part of the vehicle, the front-view camera collects video information and transmits data information to the CPU.
The working principle is as follows: the display screen is used for inputting a control instruction by a user, and analyzing and processing the video and the instruction; the wide-angle night vision high definition camera adopts a special lens which meets the requirements of large optical incident angle of an image video and real and undistorted vision of an image video reference object, and the optical lens part is adapted to normal work in severe weather such as rain, fog and the like through a special coating process; video information acquired by the wide-angle night vision high-definition camera is transmitted to the CPU through the data conversion module, and the CPU performs high-definition and high-frame-rate real-time processing on the video information and then outputs the processed video information to the display screen in real time; meanwhile, the light intensity of the surrounding environment is collected by the photosensitive sensor and then transmitted to the MCU, the MCU performs image analysis and data processing on the video information of the data conversion module, the analysis result is transmitted to the CPU, and the CPU transmits the sorted video to the display screen after performing high-definition reduction on the video information. The driver can clearly judge various complex conditions of the road behind in a larger visual angle range through the video image displayed by the display screen. Therefore, the road condition behind the vehicle can be better observed, and the position relation between the vehicle and the person causing the danger and the vehicle and the person can be judged. Meanwhile, after the video of the front-view camera is imported, the front-view and rear-view double-video-recording functions are realized, and the video recording and storage for the first 8 seconds and the second 9 seconds can be realized under special conditions.
