Abstract

The invention relates to a method for realizing combined display of multi-picture video in the blind area of ​​a commercial vehicle, which is implemented by means of a display screen, a blind area camera module, a video switching logic controller, an application processor, and a surround view camera module respectively installed on the vehicle ;The blind spot camera module includes a front left camera, a front right camera, a rear center camera, a front center camera, a rear left camera, and a rear right camera for respectively taking pictures of the corresponding viewing angle directions; including step 1, first, install the surround view on the car Camera module, then, according to the car model and the blind spot of looking around the camera module, adjust the angle of view of each camera in the blind area camera module, the blind area formed by the angle of view of each camera is covered by the blind area of ​​looking around; the present invention is reasonable in design, compact in structure and Easy to use.

Description

technical field [0001] The invention relates to a method for realizing multi-picture video combined display in blind spots of commercial vehicles. Background technique [0002] At present, the mainstream products for assisting driving in the blind spot of passenger cars using video imaging technology are 360-degree panoramic view, and blind spot assisting camera products installed in the left and right rearview mirrors and interior rearview mirrors. Because the 360-degree panoramic view has serious image distortion, the range of effective images is too short, and it does not conform to people's traditional visual habits. Even if users install the panoramic view product, the frequency of use is very low. Left, right and inner rear view blind spot products only solve part of the blind spots in the left and right rear areas of passenger cars. Passenger car blind spot auxiliary display screen and entertainment navigation screen are shared, and the functions of the two products ...

AI Technical Summary

Problems solved by technology

Passenger car blind spot auxiliary display screen and entertainment navigation screen are shared, and the functions of the two products will affect each other when users use them; at the same time, the existing blind spot auxiliary video images are all single-screen, and the combined video images of multiple cameras that meet visual habits cannot be displayed at one time , so that the comprehensive information of the blind spot assist video image that the driver sees on the entertainment screen at one time is very little

Existing passenger car BSD products only display alarm information on the left and right rearview mirrors in the form of flashing lights when the vehicle speed is higher than a certain speed.

Due to the particularity of commercial vehicle models, the blind spots of commercial vehicles are larger than those of passenger vehicles, but because of the professionalization of commercial vehicle drivers, fewer display screens are installed than those of passenger vehicles, or the rear view screen has a single function, and the application of new technologies is higher than that of passenger vehicles. Due to lag and other reasons, the existing commercial vehicle blind spot auxiliary products are basically blank

Existing buses are equipped with intelligent dispatching screens as standard. If the blind spot auxiliary display screen is shared with the intelligent dispatching screen, the functions of the two products will affect each other when users use them.
