Research On Image Magnification Technology In Three Dimension Display

3D display system can be applied to many wide-ranging field, such as: industry, business, medicine, architecture and art etc. Especially, It is very important to military application. This paper investigated the image procedure of 3D display based on the SynthaGram auto-stereo-display monitors.Firstly, foundational mechanism of auto-stereo-display was presented. The requirements for image processing in auto-stereo-display, high image resolution and fast procedure speed, were deduced from such mechanism. The interpolation based on the refinement of shape-profiles was adopted for image magnifications as fast as possible, after analysing main advanced methods of image magnifications.Secondly, a new algorithm of smoothness shape-profiles was studied by analogy the thermal diffusion. The new method can decrease the cost of computation because of its simpler algorithm and smaller number of points in shape-profiles. Moreover, interpolation based on such smoothed profiles was also improved for higher accuracy. The comparison was performed through MATLAB platform in a series of cases, and the results show that both of two improvements are successful.Thirdly, the new method and nearest-neighbor method, single linear interpolation, bilinear interpolation were coded by VC++, and a MFC application, BmpInterpolation, was achieved. Many kinds of examples were tested using BmpInterpolation, including single color images and true color images (24bits), photos and images after 3D rendering by 3DMax. The comparison between new method and the others indicates that the new method can not only get higher quality of images but also match the requirement of procedure speed.At last, integration of the new method and relative module of SynthaGram SDK was conducted. By using the Texture and other Direct3D functions, the realization of the new image technology developed in this paper was fulfilled successfully.
