Device and method for eliminating dead zones of automobile A columns

Abstract

The invention provides a device and method for eliminating dead zones of automobile A columns and belongs to the technical field of automobile equipment. The device comprises a central processor, an outdoor scene acquisition device and display devices, wherein the outdoor scene acquisition device and the display devices are connected with the central processor respectively, the display devices are arranged on the inner surfaces of the A columns on the two sides of an automobile, and the central processor, the outdoor scene acquisition device and the display device are all arranged in the automobile. The outdoor scene acquisition device comprises two camera groups corresponding to the A columns on the two sides of the automobile, each camera group comprises a front camera and a rear camera, the front camera is used for acquiring outdoor scenes in front of the corresponding A column on one side of the automobile, and the shooting area of the rear camera covers the front camera in the same group as the rear camera and the A column on the corresponding side of the automobile. The invention further comprises an image regulation system connected with the central processor. The device has the advantages of being free of effect on appearance of the automobile, good in elimination effect on the dead zones of the automobile A columns, small in picture delay and high in displayed images, wire displacement of devices is simple.

Description

technical field [0001] The invention belongs to the technical field of automobile equipment, and relates to a device and a method for eliminating the blind area of ​​an A-pillar of an automobile. Background technique [0002] The A-pillar of the car is the pillar between the front windshield and the front door of the car. It mainly serves as a structural support. However, due to the special position of the A-pillar, it will block part of the driver's line of sight and form a visual blind spot. [0003] In the prior art, there are mainly two methods for eliminating the A-pillar blind area: [0004] One, the perspective method, such as the Chinese patent whose publication number is "CN203345050U", provides a viewing strip equipped with transparent glass on the A-pillar, and the driver can directly see the scene ahead through the transparent part of the A-pillar. The main defects are that the rigidity of the A-pillar is reduced, and the elimination effect of the blind zone is ...

Problems solved by technology

The main disadvantages are: the rigidity of the A-pillar is reduced, and the elimination effect of the blind zone is not ideal

There are two main defects: first, the camera installed outside the vehicle is easy to damage the streamline design outside the car, affecting the appearance, and the equipment is easy to be lost and damaged, and at the same time increases the difficulty of wiring; second, the screen display delay Large and low precision, the reason is that the external image data is too large, and the implementation of the cutting action is based on too few parameters, that is, only the captured driver's facial line of sight parameters are used to determine how to cut the acquired external image data
