Augmented reality display technology-based driving assistance system and method

Abstract

The invention discloses a driving assistance system and method based on augmented reality display technology. The solution recognizes the target vehicle in real time and its relationship with the vehicle itself, and at the same time forms a driving assistance correction based on the driver's perspective image based on the driver's perspective image. information, and then render and form a corrected driving assistance image based on this, and display the corrected driving assistance image in the driver's perspective through an augmented reality display system. Based on this, the driving assistance scheme is based on the real-time correction of auxiliary information based on the driver's perspective, and the auxiliary information is associated with the real driving environment through the head-up display technology, which effectively solves the problems existing in the information prompt of the existing driving assistance system.

Description

technical field [0001] The invention relates to a vehicle driving safety technology, in particular to a vehicle driving assistance scheme. Background technique [0002] The driver's perception ability is limited. If the judgment and decision-making is wrong during driving, it is easy to cause traffic accidents. In order to reduce traffic accidents caused by driver negligence and mistakes, forward collision warning system (FCW) and lane departure warning system (LDW) Wait for the driver assistance system to emerge as the times require. These driving assistance systems remind the driver to pay attention to safety through sound, light, vibration and other forms when there is danger, so as to avoid traffic accidents caused by the driver's wrong judgment and decision-making. [0003] However, the existing driving assistance system only issues an early warning when there is danger, which often causes the driver's psychological stress due to the sudden alarm, and the alarm time ca...

AI Technical Summary

Problems solved by technology

[0003] However, the existing driving assistance system only issues an early warning when there is danger, which often causes the driver's psychological stress due to the sudden alarm, and the alarm time cannot satisfy the driving experience of all drivers. When the driver thinks that the alarm time is unreasonable , the driver will often turn off the system

[0004] In addition, the alarm information display of most existing driving assistance systems can only rely on the display screen of the car entertainment system, and the position of the display screen of the car entertainment system is far from the driver's normal driving line of sight. Alarm information, if the driver watches the alarm information, there is a risk of ignoring the road conditions ahead and causing traffic accidents

A small number of driving assistance systems use the head-up display system (HUD) to display alarm information, but the displayed content is still limited to simple target information and alarm information, which is of limited help to the driver's driving operation. Even if the concept of augmented reality is proposed, It also fails to solve the problem of the driver's line of sight change. The existing augmented reality driving assistance system proposed to identify the driver's perspective through the camera in the car has not been widely used in practice due to the poor algorithm effect.
