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 utility model, comprising 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 utility model additionally provides a kind of projection arrangement of sectioning image, including image source carrier 1, light
Source array 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

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
Have sectioning image in same limiting time stablize imaging, make the utility model use LCD display as image source carrier at
It is possible.
It is led in addition, editor's projection arrangement of sectioning image provided by the embodiment of the utility model 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.
