一种通过DMD拼接实现的分辨率提高的方法
摘要：
一种通过DMD拼接实现的分辨率提高的方法。本发明属于提高DMD分辨率的技术领域。它的方法步骤一、在计算机上将4k×4k的图像通过图像分割的方法分为4k×2k、4k×2k两部分；二、将DMD1芯片放置在双层固定台的底层固定台上的滑动导轨上，DMD2芯片固定放置在双层固定台的上层固定台上；三、DMD控制芯片将上述两部分图像信号进行处理后，将上述两部分4K×2K的图像分别同时传输到DMD1芯片和DMD2芯片中；四、通过高分辨率CCD相机对DMD1芯片像素和DMD2芯片像素成像，再通过精确位置移动平台能驱动DMD1芯片做相对于双层固定台的底层固定台台面做精密平行位移，使DMD1芯片边缘像素与DMD2芯片边缘像素之间的距离达到标称值。本发明能实现将两块DMD芯片像无缝拼接，大幅度提高DMD芯片的分辨率。
摘要（英）：

The invention discloses a resolution enhancement method realized through DMD splicing, which belongs to the technical field of DMD resolution enhancement. The method comprises steps: 1, a 4k*4k image is segmented into a 4k*2k part and a 4k*2k part on a computer in an image segmentation method; 2, a DMD1 chip is placed on a sliding guide rail of a bottom fixing table of a dual-layer fixing table, and a DMD2 chip is fixedly placed on an upper fixing table of the dual-layer fixing table; 3, a DMD control chip processes signals of the above two image parts, and the above two 4k*2k images are simultaneously transmitted to the DMD1 chip and the DMD2 chip respectively; and 4, DMD1 chip pixel imaging and DMD2 chip pixel imaging are carried out via a high-resolution CCD camera, the DMD1 chip is driven to perform precise and parallel displacement in relative to the bottom fixing table surface of the dual-layer fixing table via a precise position moving platform, and thus the distance between a DMD1 chip edge pixel and a DMD2 chip edge pixel reaches a nominal value. Two DMD chip images can be seamlessly spliced, and the resolution of the DMD chip can be greatly improved.
