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
The present invention relates to a kind of imaging region finding method, belong to automobile ergonomics field.
Background technology
For satisfying the demand of automotive market differentiation, personalization, a lot of instantly vehicles have been loaded the DVD read-out on instrument carrier panel, increased the amusement function and the navigation feature of automobile, make automotive trim more fashion, trend simultaneously, are full of modern sense.
But when night running, the light that the DVD read-out sends forms inverted image on windscreen, causes driver's forward visibility to be affected.For reducing this phenomenon, in the automotive development process, must control the imaging region of DVD read-out on windscreen, to reduce automobile potential safety hazard in the process of moving.
Summary of the invention
The technical matters that the present invention will solve is to overcome existing defective, and the method for a kind of DVD of asking read-out imaging region on windscreen is provided, and is convenient to carry out automobile DVD and dazzles the eyes check.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of method of asking DVD read-out imaging region on windscreen according to the rectilinear propagation and the law of reflection of light, is estimated the rectangular area at the picture place of DVD read-out on windscreen, according to accuracy requirement, at this area arrangements matrix point set.
On the DVD read-out, find out unique point, four summits of getting the DVD read-out are unique point.Through attempting, seek the boundary point that each unique point gets into the picture of eyellipse, thereby find out the imaging region of each unique point on windscreen, in conjunction with the contour feature of DVD read-out, on windscreen, depict approximate imaging region.
The invention has the beneficial effects as follows: through the design's check method; The method of a kind of DVD of asking read-out imaging region on this curved surface of windscreen has been proposed; In the car load development process; Improved the efficient that DVD dazzles the eyes check,, eliminated the potential safety hazard that exists in the driving for the layout of DVD provides important reference frame.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification sheets, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the solution procedure scheme drawing of DVD read-out imaging region on windscreen among the present invention;
Fig. 2 is the solving result scheme drawing of DVD read-out imaging region on windscreen among the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Among Fig. 1,, estimate out the rectangular area at the picture place of DVD read-out 5 on windscreen, in this rectangular area, arrange the matrix point set according to the rectilinear propagation and the law of reflection of light.Four summits of getting DVD read-out 5 are unique point a, b, c, d, are set out to concentrate at matrix dot by a point and find out the boundary point that just gets into eyellipse 4, make incident ray 1, and incident ray 1 obtains reflected light rays 2 through windscreen 3 reflections.According to above-mentioned steps, concentrate the boundary point of finding out each entering eyellipse 4 at matrix dot.The profile scope that boundary point surrounds is exactly the imaging region of unique point a on windscreen.Find out the imaging region of unique point b, c, d after the same method.
Among Fig. 2, in conjunction with the contour feature of DVD read-out, on windscreen 3, make the imaging region of approximate DVD read-out according to method of geometry, this zone is the imaging region of being asked 6.
What should explain at last is: the above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. method of asking DVD read-out imaging region on windscreen; It is characterized in that: estimate the rectangular area at the picture place of DVD read-out on windscreen, according to accuracy requirement, at this area arrangements matrix point set; On the DVD read-out, find out unique point; Through attempting, seek the boundary point that each unique point gets into the picture of eyellipse, thereby find out the imaging region of each unique point on windscreen; In conjunction with the contour feature of DVD read-out, on windscreen, depict approximate imaging region.
2. a kind of method of asking DVD read-out imaging region on windscreen according to claim 1 is characterized in that: four summits of getting the DVD read-out are unique point.
