Abstract:
A LED-based integral imaging display system as well as its control method and device, including: a parameter matching step: matching the parameters of the lenslet array and LED in the display part of said LED-based integral imaging display system to obtain the display parameters. The display parameters include the basic parameters of the display part, and the corresponding optical imaging models, which match with the basic parameters, in different stereoscopic display modes. A video source acquisition step: according to the display parameters, acquiring the integral imaging video sources required by LED-based integral imaging naked-eye stereoscopic display, which is used for the to-be-displayed 3D image.

Claim (Index 9):
The method according to  claim 7 , wherein:\n calculating the disparity maps of the images at different viewing angles includes: for each pixel in one captured image, calculating the mean square error functions within a certain horizontal range relative to its horizontally neighboring images; selecting the shift with the minimum mean square error as the horizontal disparity of this pixel; then the horizontal disparity map of said image is obtained; for each pixel in one captured image, calculating the mean square error functions within a certain vertical range relative to its vertically neighboring images; selecting the shift with the minimum mean square error as the vertical disparity of this pixel; then the vertical disparity map of said image is obtained; and reconstructing 3D points of the to-be-displayed 3D object includes: determining the coordinates of said 3D point, according to the focal length of said real camera, the distance between the point and the leftmost real camera, the disparity maps of the images at different viewing angles, the distances between the imaging points of this point in different real cameras and the corresponding image centers of the real cameras; and generating the elemental image array includes: determining the positions of the imaging points of the to-be-displayed 3D object in said elemental lens, according to the coordinates of 3D point of the to-be-displayed 3D object, the center positions of the elemental lens in said lenslet array, and the focal length of said elemental lens; recording the RGB values of the 3D object projected within the imaging range of said elemental lens into the elemental image corresponding to the elemental lens; arranging all elemental images of said lenslet array into an array to obtain said elemental image array.
