Embodiment Construction

[0012] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0013] figure 1 In , according to the law of linear propagation and reflection of light, the rectangular area where the image of the DVD display screen 5 on the windshield glass is located is estimated, and the matrix point set is arranged in this rectangular area. Take the four vertices of the DVD display 5 as feature points a, b, c, d, start from point a and find out the boundary point that just enters the eye ellipse 4 in the matrix point set, and make the incident ray 1, and the incident ray 1 passes through the front wind The window glass 3 is reflected to obtain the reflected ray 2 . According to the above steps, each boundary point entering the eye ellipse 4...

Abstract

The invention provides a method for solving an imaging area of a DVD (digital versatile disc) display screen on front windshield glass. A rectangular area of images of the DVD display screen on the front windshield glass is estimated according to light rectilinear propagation and reflection laws, and matrix point sets are distributed in the area according to precision requirements. The method includes: fining feature points on the DVD display screen, taking four vertexes of the DVD display screen as the feature points, finding boundary points of feature point images entering eye ellipses through trials to find the imaging area of each feature point on the front windshield glass, and drawing a similar imaging area on the front windshield glass according to outline features of the DVD display screen. The method for solving the imaging area of the DVD display screen on the front windshield glass which is a curved surface is provided through a checking method, DVD glaring checking efficiency is improved during integral automobile development, significant reference basis is provided for DVD arrangement, and potential safety risks in running of automobiles are eliminated.

Description

technical field [0001] The invention relates to a method for finding an imaging area, which belongs to the field of automobile ergonomics. Background technique [0002] In order to meet the needs of differentiation and individualization in the automobile market, many current car models are equipped with DVD display screens on the dashboard, which increases the entertainment function and navigation function of the car, and at the same time makes the car interior more fashionable, trendy and full of modernity. [0003] However, when driving at night, the light emitted by the DVD display screen forms an inverted image on the windshield, which affects the driver's front view. In order to reduce this phenomenon, in the process of automobile development, it is necessary to control the imaging area of ​​the DVD display screen on the front windshield, so as to reduce the safety hazards of the automobile during driving. Contents of the invention [0004] The technical problem to b...
