Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
In slice type projection imaging system, movement screen does straight reciprocating motion, or spin movement or rotary motion, Scan three-dimensional imaging space.During movement screen movement, high speed projection arrangement successively shields projection three-dimension object to movement N number of two dimension slicing, movement screen in different positions receives these sectioning images as target screen, in true three-dimensional space shape It include " the slice stack " of N number of sectioning image at one.If the speed of movement screen movement is sufficiently fast, and high speed projection arrangement is thrown The slice numbers N penetrated is sufficiently large, and due to visual persistence effect, human eye just can be perceived has actual physical deep in imaging space The stereo-picture of degree.
A kind of edit methods of sectioning image provided by the invention, include the following steps:
The array distribution in image source carrier of N number of sectioning image needed for body 3-D image being constituted is imaged;
The sectioning image in described image source carrier is projected on target screen with time sequencing by projection arrangement.
As shown in Figure 1, the present invention also provides a kind of projection arrangement of sectioning image, including image source carrier 1, light source battle array Column 2, circuit board 3, lens array 4;
As shown in connection with fig. 2, described image source carrier 1 can be film, LCD display or LCD projection chip, and by structure The array distribution on described image source carrier 1 of N number of sectioning image 101 needed for adult 3-D image is imaged;
The array of source 2 is located at the side of described image source carrier 1, and described image source carrier 1 is made to be located at the light source On the light direction of array 2, the array of source 2 includes several for illuminating sectioning image 101 in described image source carrier 1 Point light source 201, point light source 201 uses light-emitting LED patch in the present embodiment, and the point light source 201 and described image source carry The distribution mode of body 1 matches;The array of source 2 is electrically connected with the circuit board 3, passes through the circuit board 3 and its monolithic Machine controls lighting and extinguishing for point light source 201 in the array of source 2;
The lens array 4 is located at the other side of described image source carrier 1, and the lens array 4 is used for including several The lens that sectioning image 101 is amplified, and the distribution mode of the lens and described image source carrier 1 matches.
It further include the first shading grid 5 being made of light screening material as the improvement of above-described embodiment scheme, described first Between described image source carrier 1 and the array of source 2, the first shading grid 5 is equipped with and the light shading grid 5 The matched loophole of point light source 201 in source array 2, to guarantee that the point light source 201 only illuminates corresponding sectioning image 101.
It further include the second shading grid 6 being made of light screening material as the improvement of above-described embodiment scheme, described second Between described image source carrier 1 and the lens array 4, the second shading grid 6 is equipped with and the light shading grid 6 The matched loophole of point light source 201 in source array 2, to guarantee that each sectioning image 101 is only received by the corresponding lens.
As shown in figure 3, the projection arrangement of sectioning image provided in this embodiment, setting x*y array point in image source carrier 1 The image source carrier 1 of cloth, imaging has sectioning image 101 respectively in image source carrier 1, and the light source display under circuit board control is pressed Point light source (x, y) therein is successively lighted according to program order, sectioning image 101 corresponding with point light source is projected to the tn moment On target screen,
As an improvement of the above scheme, imaging position of the sectioning image 101 in described image source carrier, size, According to it, finally the displacement on target screen (after projection imaging), size, form variations do corresponding amendment to shape.
In this embodiment scheme, the focal length in the lens array 4 between lens is not quite similar, to guarantee each slice map It can clearly be incident upon on the target screen of movement as 101.
The driving voltage of liquid crystal molecule in LCD display must carry out reversal, this is just needed liquid crystal display Interior display voltage is divided into two kinds of polarity, and one is positive polarity, the other is negative polarity.When the voltage of show electrode is higher than When common (public electrode) electrode voltage, it is known as positive polarity;When the voltage of show electrode is lower than common electrode voltage, It is known as negative polarity.Either positive polarity or negative polarity can all have the grayscale of one group of same brightness, so working as upper layer and lower layer glass Pressure difference absolute value when being fixed, the grayscale showed is the same.But under both of these case, liquid crystal molecule It turns to but completely on the contrary, also can be to avoid the above-mentioned characteristic caused when liquid crystal molecule steering is permanently affixed to a direction It destroys.There are four types of common reversal modes, i.e. paraphase mode, line-by-line inversion mode, by column paraphase mode and point-by-point frame by frame Paraphase mode, as shown in Figure 4.Therefore, when LCD display reversal mode is " paraphase frame by frame ", whole frame institute can be formed There is sectioning image to stablize imaging in same limiting time, making the present invention that LCD display be used to become as image source carrier can Energy.
It is led in addition, the edit methods and projection arrangement of sectioning image provided in an embodiment of the present invention can also be applied in animation Domain reference object will be imaged on image source carrier frame by frame, and control continuous broadcasting by circuit board, to form movement Image.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
