Abstract

The invention provides an information display system capable of automatically adjusting the visual range and a display method of the information display system. After a sensing module is used for capturing the information of a driver and detecting the distance between the sensing module and the driver, the face feature information comprising the positions of the eyes, the face deflection angle, the drive watching position and the like of the driver is further identified to estimate the projection range, namely the position of the visual range of the driver, of the driving information on a front windshield, the position and the angle of a projection device are adjusted according to the projection range, and therefore the projection device can project a picture at the accurate position of the front windshield.

Description

technical field [0001] The invention relates to a head-up display technology, in particular to an information display system and a display method for automatically adjusting the visual range. Background technique [0002] With the advancement of science and technology and the affluence of life, the penetration rate of vehicles in various families has increased significantly. However, with the frequent use of vehicles, traffic accidents have increased, and the main cause of accidents is mostly collisions. 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 vehicle through the front windshield while driving. In front of the road conditions, there is no need to look down and distracted to watch the dashboard in the car to cause accidents, so...
