Abstract
The method for improving projection image resolution ratio is imaged jointly the present invention relates to a kind of multi-disc DMD, ultraviolet source, lens group and DMD is symmetrically placed in pairs relative to projection lens, reflecting prism is disposed vertically with projection lens, projection image information is divided into two parts, information is gathered by two panels DMD respectively, splices complete at prism after light beam reflection, then unify projection imaging, so that in the case of high-resolution, larger imaging area can be obtained again.
Description
Technical field
The present invention relates to 3D printing field, specifically a kind of multi-disc DMD is imaged the side for improving projection image resolution ratio jointly
Method.
Background technology
In DLP shadow casting techniques, its core component is a chip for being referred to as DMD.The top of dmd chip is by counting
Million areas are constituted in micron-sized eyeglass, increase the quantity of eyeglass in DMD, you can improve the resolution ratio of product, product point
Resolution is higher, then the picture quality for projecting is better.
In order to improve projection image quality, it is desirable to which the micro mirror number on dmd chip is The more the better, but no matter from cost
See, or from technical conditions, eyeglass number simultaneously impossible unconfined increase, so as to limit the projection quality of picture.
In 3D printing industry, the picture quality requirement to projecting is even more strict, and existing DMD manufacturing technologies, it is impossible to meet high-resolution
Rate exquisiteness surface, the printing requirement of details true to nature.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of multi-disc DMD and are imaged raising projection image resolution ratio jointly
Method, to solve prior art defect.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
The method that multi-disc DMD is imaged raising projection image resolution ratio jointly comprises the following steps：
1) pictorial information is divided into symmetrical two parts；
2) light source, lens group and DMD are symmetrically arranged with projection lens both sides, two parts pictorial information is passed through two respectively
The ultraviolet that side light source sends is projected, and is changed by both sides lens group, is projected on the DMD of both sides；
3) after two parts pictorial information reflects through DMD, two sides with the vertically disposed prism of projection lens are arrived separately at
Face；
4) by adjusting light source, lens group, DMD position each other and angle so that by two after refraction by prism
Part pictorial information scrabbles up the pictorial information of completion；
5) piece together complete pictorial information and enter camera lens, carry out projection imaging.
Further, described prism may be alternatively provided as reflective mirror.
The beneficial effects of the invention are as follows：The present invention is gathered to two parts of same width picture simultaneously by using two panels DMD
Information, be finally stitched together projection imaging so that in the case of high-resolution, and larger imaging surface can be obtained again
Product.
Brief description of the drawings
Fig. 1 implements structural representation for the present invention；
Specific embodiment
Principle of the invention and feature are described below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
It is non-for limiting the scope of the present invention.
The method that multi-disc DMD is imaged raising projection image resolution ratio jointly comprises the following steps：
1) pictorial information is divided into symmetrical two parts；
2) light source, lens group and DMD are symmetrically arranged with projection lens both sides, two parts pictorial information is passed through two respectively
The ultraviolet that side light source sends is projected, and is changed by both sides lens group, is projected on the DMD of both sides；
3) after two parts pictorial information reflects through DMD, two sides with the vertically disposed prism of projection lens are arrived separately at
Face；
4) by adjusting light source, lens group, DMD position each other and angle so that by two after refraction by prism
Part pictorial information scrabbles up the pictorial information of completion；
5) piece together complete pictorial information and enter camera lens, carry out projection imaging.
Further, described prism may be alternatively provided as reflective mirror.
The present invention gathers information to two parts of same width picture simultaneously by using two panels DMD, is finally stitched together
Projection imaging so that in the case of high-resolution, can obtain larger imaging area again.
Finally, these are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
