Automatic correction method for vehicle display system and system thereof

Abstract

The invention provides an automatic correction method for a vehicle display system and a system thereof. The method comprises the following steps: converting an image of a road ahead into projection information; calculating a coordinate model; detecting the facial feature of a driver; calculating a facial deflection angle and a facial feature three-dimensional position of the driver accordingly to estimate a visual field position of the driver looking in front; bringing the visual field position into an image overlapping projection conversion formula to generate an overlapping error correction parameter value; correcting and updating the coordinate model by using the overlapping error correction parameter value; projecting the corrected coordinate model in front of the driver by using a display unit to overlap the projection position of the coordinate model with the visual field position of the driver.

Description

technical field [0001] The invention relates to a technology for displaying vehicle projections, in particular to an automatic correction method and system for a vehicle display system. Background technique [0002] With the development of science and technology, life is rich, motor vehicles are becoming more and more popular in every family, and the convenience of transportation is continuously improved due to the advancement of vehicle technology. However, with the frequent use of vehicles, the number of traffic accidents increases, and most of the accidents are caused by collision cases. In order to improve the driving safety of vehicles, the head-up display device has become the basic equipment of many vehicles. It can project the driving information displayed on the general instrument panel on the front windshield of the vehicle, so that the driver can pay attention to the front of the car through the front windshield while driving. In order to increase driving safety,...

Problems solved by technology

However, due to the small size of the display screen, only simple speed information, guidance system with small arrows, information of the vehicle in front (such as the distance between vehicles), and lane information (such as lane width, offset) can be displayed, and it is impossible to make use of the virtual reality display. The driver produces an intuitive viewing effect, and needs to adjust to the driver's viewing field of view again for different driver postures. However, when the vehicle is moving, the existing HUD system information cannot dynamically change with the driver's face position. Adjustments are made so no real-time corresponding projection information is produced
