Description

Laser imaging system for vehicle

Technical Field

The utility model relates to a laser imaging field especially relates to a laser imaging system for vehicle.

Background

At present, when a driver changes lane and overtakes, the driver needs to look at the external rearview mirror from left to right, so that great influence is brought to driving operation, the electronic rearview mirror is developed in the intelligent automobile, but the driver still needs to look at the image in a head-down mode, and the driving operation is also influenced to a certain degree.

To address similar issues, such as reducing the driver's heads-down to see the instruments, a heads-up display system (HUD) was developed, which was first applied to military aircraft and functions to reduce the frequency with which the pilot needs to look down at the instruments, thereby avoiding interruptions in attention and loss of awareness of the state. HUD technology was later applied to automobiles for the same purpose, and it was desired to avoid traffic accidents caused by reducing heads down on center console displays. At present, the display content of the vehicle-mounted HUD mainly comprises navigation, vehicle speed, rotating speed and other relevant information, effective driving reference can be provided for a driver through the information, and driving safety is improved.

At present, a HUD (head Up display) does not display a rear view image, and the display effect is poor.
