Description

technical field [0001] The invention relates to a multi-picture video group display system in the blind area of ​​a commercial vehicle. 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 will affect...

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.

The existing blind spot auxiliary video images are all single-screen, and grouped video images of multiple cameras that meet visual habits cannot be displayed at one time, resulting in too little comprehensive information of the blind spot auxiliary video images that the driver sees on the dispatching screen at one time

At the same time, the installation position of the existing display screen is lower, and the driver will have the risk of secondary blind spots ahead when looking at the display screen.
