Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, there is shown of the present utility model a kind ofly, comprising based on the full visual angle three-dimensional display system of looking barrier grating and LED:
One motor 3, this motor 3 are connected with one 6 to drive this axle 6 rotations;
Two right-angled intersections and fixedly connected branch control and mechanical connection plate 2, the central shaft of its cross fixation are axle 6, are uniformly distributed with several LED4 (light emitting diode) on two limits parallel with axle 6 of dividing control and mechanical connection plate 2;
And the master control board 5 that minute control be arranged in parallel and is fixed in the control LED4 between the LED4 on both sides with mechanical connection plate 2, this master control board 5 by SPI (not shown) (Serial Peripheral Interface) to LED4 transmission data message;
Encircle looking outside minute control and mechanical connection plate 2 and hinder grating 1, this is looked barrier grating 1 and is provided with and encircles into annular perpendicular to axle 6, and this pitch of looking barrier grating 1 is 36 line/inches.
In the utility model, each divides the LED4 on same one side of control and mechanical connection plate 2 to constitute a LED line source, the LED line source that divides control and mechanical connection plate 2 to realize rotation by rotation, the LED line source by rotation and look barrier grating 1 and constituted display screen.The utility model uses 4 groups of LED line sources, reaches 2 meters of girths and high 0.5 meter big picture stereoscopic picture plane.The branch luminosity of entire display screen reaches 92%, and three-dimensional degree reaches 18.
The utility model is a kind of based on the high-speed data parallel processing output auto-stereo display system of looking barrier grating and two-dimentional LED rotation.This system can walk abreast and light LED4 on the rotary screen, improves their demonstration speed, satisfies the broadcast demand of dynamic image.
Multi-angle is obtained subject image, and the parallax stereoscopic picture plane is synthesized in the position according to three-dimensional vision area on the display screen in computing machine; Use the core of ARM Cortex-M3, three-dimensional composograph is arrived each LED4 by the high speed SPI broadcast distribution as master control board 5; Each LED4 shows the image in this moment simultaneously at stereopsis zone position place separately, and along with the rotation of display screen, each three-dimensional vision area is scanned, and this display screen just can form stereopsis in three dimensions scanning.
Principle of work:
1. multi-angle is obtained subject image, can be 360 degree multi-angle shoot on locations, can be that the computing machine (not shown) is made back 360 degree and set up a plurality of video camera (not shown)s, it is consistent that multi-angle number of cameras and looking hinders the three-dimensional vision area quantity that grating 1 provides.
