Head-up displayer, adjustment method of head-up displayer, mobile terminal and computer readable medium

Abstract

The embodiment of the invention provides a head-up displayer, an adjustment method of the head-up displayer, a mobile terminal and a computer medium and belongs to the technical field of optical projection. The method comprises the steps that an adjustment instruction input by a user is received, and an adjustment parameter is generated according to the adjustment instruction; the adjustment parameter is sent to the head-up displayer, and the head-up displayer refreshes a displayed virtual image according to the adjustment parameter. According to the method, the problems are solved that in thevirtual image displaying process of the head-up displayer, due to design, structures, installation errors and the like, distortion, inclination, position problems, size problems, fuzzy problems and the like of pictures are caused, and accordingly the visual sense of an observer is uncomfortable; therefore, the user can conveniently and quickly adjust the display state of the virtual image of thehead-up displayer according to his / her visual sense habits, and the visual comfort feeling of the user is improved.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a head-up display and an adjustment method thereof, a mobile terminal and a computer-readable medium. Background technique [0002] Head Up Display (HUD for short) was originally used on aircraft to provide pilots with a larger field of view. At present, HUD has been used in vehicles. It is a comprehensive electronic display device for automobiles composed of electronic components, optical display components and control components. It can project vehicle speed, navigation information, active safety warning signals, etc., in the form of images and characters, onto the windshield directly in front of the driver through an optical display component to form a virtual image. When the driver observes the road conditions outside the vehicle, he can see the images, characters and other information superimposed on the external scene at the same time. Since its projection focal length i...

Problems solved by technology

[0003] At present, HUD generally uses fixed-surface reflection technology to complete virtual image projection. Because the optical design cannot completely avoid display image deformation, and different people have different heights, driving habits, and visual habits, the HUD cannot be fully adapted, resulting in the observer's visual Discomfort

In addition, the installation accuracy of HUD is relatively high, and it is difficult to match the visual habits of users, resulting in the problem of low visual comfort for users.
