Abstract
The invention provides a kind of method asking DVD read-out imaging region on windscreen, according to rectilinear propagation and the law of reflection of light, estimate the rectangular area at the picture place of DVD read-out on windscreen, according to accuracy requirement, arrange matrix point set in this region.DVD read-out finds out unique point, and four summits of getting DVD read-out are unique point.By attempting, finding the boundary point that each unique point enters the picture of eyellipse, thus finding out the imaging region of each unique point on windscreen, in conjunction with the contour feature of DVD read-out, windscreen being depicted approximate imaging region.By the design's check method, propose a kind of method asking DVD read-out imaging region on this curved surface of windscreen, in automobile research process, improve the efficiency that DVD dazzles the eyes check, layout for DVD provides important reference frame, eliminates the potential safety hazard existed in driving.
Description
Technical field
The present invention relates to a kind of imaging region finding method, belong to automobile ergonomics field.
Background technology
For meeting automotive market differentiation, personalized demand, a lot of vehicle is loaded with DVD read-out on the dash panel instantly, adds amusement function and the navigation feature of automobile, makes automotive trim more fashion, trend simultaneously, be full of modern sense.
But when night running, the light that DVD read-out sends forms inverted image on windscreen, the forward visibility of driver is caused to be affected.For reducing this phenomenon, in automotive development process, must the imaging region of control DVD read-out on windscreen, to reduce automobile potential safety hazard in the process of moving.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of method asking DVD read-out imaging region on windscreen, 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:
Ask a method for DVD read-out imaging region on windscreen, according to rectilinear propagation and the law of reflection of light, estimate the rectangular area at the picture place of DVD read-out on windscreen, according to accuracy requirement, arrange matrix point set in this region.
DVD read-out finds out unique point, and four summits of getting DVD read-out are unique point.By attempting, finding the boundary point that each unique point enters the picture of eyellipse, thus finding out the imaging region of each unique point on windscreen, in conjunction with the contour feature of DVD read-out, windscreen being depicted approximate imaging region.
The invention has the beneficial effects as follows: by the design's check method, propose a kind of method asking DVD read-out imaging region on this curved surface of windscreen, in automobile research process, improve the efficiency that DVD dazzles the eyes check, layout for DVD provides important reference frame, eliminates the potential safety hazard existed in driving.
Accompanying drawing explanation
Accompanying drawing is used to provide a further understanding of the present invention, and forms a part for specification sheets, together with embodiments of the present invention for explaining the present invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the solution procedure schematic diagram of DVD read-out imaging region on windscreen in the present invention;
Fig. 2 is the solving result schematic diagram of DVD read-out imaging region on windscreen in the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
In Fig. 1, according to rectilinear propagation and the law of reflection of light, estimate out the rectangular area at the picture place of DVD read-out 5 on windscreen, in this rectangular area, arrange matrix point set.Four summits of getting DVD read-out 5 are unique point a, b, c, d, and by a point, concentrate the boundary point found out and just enter eyellipse 4 at matrix dot, make incident ray 1, incident ray 1 reflects through windscreen 3, obtains reflected light rays 2.According to above-mentioned steps, concentrate at matrix dot and find out the boundary point that each enters eyellipse 4.The profile 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.
In Fig. 2, in conjunction with the contour feature of DVD read-out, make the imaging region of approximate DVD read-out according to method of geometry on windscreen 3, this region is required imaging region 6.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. ask the method for DVD read-out imaging region on windscreen for one kind, it is characterized in that: the rectangular area estimating the picture place of DVD read-out on windscreen, according to accuracy requirement, matrix point set is arranged in this region, DVD read-out finds out unique point, by attempting, find the boundary point that each unique point enters the picture of eyellipse, thus find out the imaging region of each unique point on windscreen, in conjunction with the contour feature of DVD read-out, windscreen is depicted approximate imaging region.
2. a kind of method asking DVD read-out imaging region on windscreen according to claim 1, is characterized in that: four summits of getting DVD read-out are unique point.
