Summary of the invention
The technical matters that the present invention will solve is at automobile DVD screen the brim of a hat engineering development in earlier stage, promptly it is carried out the visual field and checks, and control and satisfy the daily operating needs of chaufeur after it is installed.
In order to solve the problems of the technologies described above; The invention provides a kind of check method about the band the brim of a hat DVD read-out visual field; According to the rectilinear propagation and the law of reflection of light, through the brim of a hat modelling feature influence of light ray propagation is analyzed, be prerequisite to satisfy the driver's seat requirement; Keep the brim of a hat shaping style and be the basis, the engineering development of the control the brim of a hat.
The objective of the invention is to realize through following technical scheme:
A kind of check method about the band the brim of a hat DVD read-out visual field comprises: check the brim of a hat and inner source light is propagated the influence that reaches driver's seat.
Wherein check the influence of the brim of a hat to driver's seat, its specifically check process is:
In data, get all on the edge of the visibility region of DVD read-out and layout, each point is the unit, realizes that with software point is to the tangent taper envelope of eyellipse.Each has just formed the field range (all layout more intensive, check more accurate) of whole eyellipse to the DVD read-out after all layouting and all accomplishing like above-mentioned method.Check the relation of the above-mentioned visual field envelope and the brim of a hat from each visual angle, if not do not intersect then explain that the visual field do not block; Explain that if the visual field envelope and the brim of a hat intersect the visual field blocks, the position of blocking is crossing place, then can suitably revise the brim of a hat, avoids visual field envelope to guarantee the brim of a hat;
Check the influence that the brim of a hat is propagated inner source light, its specifically check process is:
⑴ be with the overall reflective face with the front windshield glass inner face, gets on the whole a little as the reflector element face.Extracting the boundary line of the brim of a hat outer, is object with this boundary line, serves as with reference to doing zoom operations, obtain distant place and the equiform curve in the brim of a hat boundary line, using the multi-section order to realize connecting the curved surface of these two curves with the reflector element point.This curved surface and DVD screen intersect the light that sends in the DVD screen zone below the intersection that obtains all can inject this reflecting point.So just can make incident ray and envelope reflected light rays tangent with the brim of a hat.
⑵ move the reflecting point on the front windshield glass, observes the variation tendency of incident ray and reflected light rays, makes the envelope of reflected light rays just tangent with eyellipse.If can not look for a reflecting point to make reflected light rays envelope and eyellipse tangent or crossing under the crossing situation of the multi-section curved surface that forms on above-mentioned the brim of a hat border and DVD screen, explain that so the light that the DVD screen sends can not form images on front windshield glass; Opposite then make promise with same procedure and do a reflecting point and make that the envelope of the reflected light rays position different with eyellipse is tangent, the zone that these reflecting points surrounded is DVD and shields the zone of on front windshield glass, forming images.
The invention has the beneficial effects as follows: through designed and checked method of the present invention; Can carry out man-machine Visual field analysis to the brim of a hat of different shaping effect; Can clearly provide occlusion area and imaging region, the brim of a hat improved be more prone to, finally develop the DVD read-out the brim of a hat that satisfies operating needs.Have the sight and the brim of a hat of practicality, both improved the class of car load interior trim, eliminated the potential safety hazard of existence in the driving again.
