Description

Technical Field

[0001] This invention relates to the field of electronic rearview mirror demonstration technology, specifically to an electronic rearview mirror demonstration device. Background Technology

[0002] Traditional rearview mirrors are optical lenses mounted on both sides of the driver's side in a car. While driving, the driver observes the rear view by moving their head. Electronic rearview mirrors, on the other hand, record images of a designated rear view using cameras, process them via a miniature PC, and transmit them to a fixed display screen. The driver can then clearly see the rear view by observing the image on the screen. In the context of the era of intelligent vehicles, electronic rearview mirrors can also be integrated with ADAS (Advanced Driver Assistance Systems) and DMS (Driver Management Systems), representing a future development trend.

[0003] The widespread application of electronic rearview mirrors relies heavily on technology promotion and demonstration. Currently, most demonstrations of the working principles and imaging effects of electronic rearview mirrors rely on animated simulations. While these simulations generally accurately reflect the working principles, they lack realism in demonstrating the imaging effects, significantly diminishing the effectiveness of the demonstration. Another method involves directly mounting the electronic rearview mirror on a vehicle and having personnel enter the driver's cabin for a physical demonstration. While this method provides excellent results, it lacks flexibility and is difficult to implement in widespread promotional activities. Summary of the Invention

[0049] In summary, during the demonstration of the working principle and display effect of the electronic rearview mirror, camera 2 captures images (i.e., simulates the rear view of the vehicle). The images captured by camera 2 are transmitted to micro PC 4 for processing. The processed information is then transmitted to LBS optical engine 5. LBS optical engine 5 projects the image directly onto screen panel 6 through projection hole 1.1.6 and projection slot 1.1.1. The observer can then see the simulated rear view of the vehicle by observing screen panel 6. The projection light path of LBS optical engine 5 matches the projection slot 1.1.1 to ensure a complete image is displayed on screen panel 6.
