Abstract
The invention relates to a head-mounted three-dimensional digital projection image viewing device, which comprises a head-mounted bracket 1, a left-mounted digital minisize projector 2, a right-mounted digital minisize projector 3, a left channel earphone 4, a right channel earphone 5 and a reflective screen 6, and is characterized in that the left side of the head-mounted bracket 1 is provided with the left-mounted digital minisize projector 2; the right side of the head-mounted bracket 1 is provided with the right-mounted digital minisize projector 2; and the reflective screen 6 is mounted in front of the frontal face of the head-mounted bracket 1. The device with the head-mounted minisize projectors for viewing three-dimensional digital projection images not only reduces the volume of the prior stereo projection device and lightens the weight of the same, but also is convenient for personal carrying and application; besides, the problem of brightness of using the digital minisize projectors to view the three-dimensional digital projection images is solved so that the projection images in view have high brightness and beautiful colors, and the pictures are lifelike; and simultaneously under the condition with the interference of ambient light, good three-dimensional projection effect can also be seen.
Description
Technical field
The invention belongs to digital projector arena, be specifically related to a kind of head-wearing 3 D digital projection picture viewing apparatus.
Background technology
Along with the continuous progress of digital projection technique, the range of application of stereoprojection more and more widely.But, because existing stereo projection apparatus will adopt two stage bodies to amass bigger projector, therefore carrying inconvenience when watching, also can't popularize at present in individual application.Meanwhile, a kind of digital minitype projection machine fast development that is applied to individual field is as pocket projector, mobile phone projectors or the like.The advantage of this individual minitype projection machine is: volume is small and exquisite in light weight, and is easy to carry; Weak point is that projection light source brightness is low.If can improve the brightness of watching of this digital minitype projection machine, so this numeral is little. and type projector just can be combined into the lightest individual and watch three-dimensional image equipment, and can promote the universal development of 3 D stereo shadow casting technique in individual application energetically.
Therefore, improving the brightness of watching of present digital minitype projection machine, is the technical barrier that utilizes this digital minitype projection machine to watch three-dimensional image to solve.
Summary of the invention
In order to improve the brightness of watching of present digital minitype projection machine, utilize the lightest individual of this digital minitype projection machine combination to watch three-dimensional image equipment.The invention provides a kind of individual and use head-wearing 3 D digital projection picture viewing apparatus, not only solve the brightness problem of watching of digital minitype projection machine, and solved the concrete scheme of utilizing the lightest individual of digital minitype projection machine combination to watch three-dimensional image equipment.
Technical scheme of the present invention is: at first, three-dimensional imaging principle according to " left eye is seen left figure; right eye is seen right figure ", two small and exquisite digital minitype projection machines are passed through the wear-type support as stereophone, directly be worn on beholder's head, with the method for " left eye is seen left machine, and right eye is seen right machine ", realized the principle requirement of three-dimensional imaging from the technical pattern of device.Secondly, adopt a kind of narrow visual angle microballon reflectorized material as the reflection screen of watching 3 D digital projection picture, the characteristics of this material are: as ray cast during to this material, if watch the angle between angle and the angle of incidence of light more little, watch the reflection ray on this material just strong more, otherwise the big more reflected light of angle is just weak more.In this device, the projection lens of numeral minitype projection machine and beholder's eyes stick together, that is to say that the angle of watching between angle and the angle of incidence of light is very little, although therefore the projection brightness of digital minitype projection machine is low, but under the strong reflection of this narrow visual angle screen, the beholder also can see the 3 D stereo projected image extremely bright, beautiful in colour, that picture is true to nature from this screen, and this image can not be subjected to the interference of surround lighting.This device also is equipped with the left and right acoustic channels earphone simultaneously, can hear synchronous stero set when watching 3 D digital projection picture, has realized comprehensive whole of audiovisualization.Watch common two-dimensional image as need, close a digital minitype projection machine and get final product, very convenient.
Thus, this programme adopts the novel viewing apparatus of wearing minitype projection machine, utilize the reflection characteristic of narrow visual angle projection screen, successfully solve present digital minitype projection machine and watched the low difficult problem of brightness of image, make the 3 D digital projector equipment move towards lighting, paved road in individual application development for promoting stereo projection technology energetically.
Technical scheme of the present invention can realize by following measure: a kind of head-wearing 3 D digital projection picture viewing apparatus, include that wear-type support 1, a left side are put digital minitype projection machine 2, digital minitype projection machine 3, L channel earphone 4, R channel earphone 5 and reflection screen 6 are put in the right side, it is characterized in that: a left side is installed in the left side of wear-type support 1 puts digital minitype projection machine 2, the back of putting digital minitype projection machine 2 on a left side is equipped with L channel earphone 4; The right side is installed on the right side of wear-type support 1 puts digital minitype projection machine 3, the back of putting digital minitype projection machine 3 on the right side is equipped with R channel earphone 5, has set up reflection screen 6 in positive the place ahead of wear-type support 1.This reflection screen 6 is a kind of narrow visual angle microballon reflectorized materials, when angle of incidence of light be 5 °～50 °, when viewing angle is 1 °, its retro-reflecting coefficient is 80～20.
Advantage of the present invention is: adopt the device of wearing minitype projection machine to watch 3 D digital projection picture, dwindle and alleviated the volume and weight of existing stereoprojection equipment, be convenient to very much the individual and carry and use; Utilize the reflection characteristic of narrow visual angle projection screen, solved digital minitype projection machine and watched the brightness problem of 3 D digital projection picture, not only made projected image brightness height, beautiful in colour, picture is true to nature, and having under the situation of ambient light interference, also can see good stereoprojection effect; Low cost of manufacture is convenient to popularize.
