TS和MS之间的主要区别在于合成互补图像的过程。TS需要在您进入系统之前生成所有互补图像。这是因为TS采用了基于相机的方法。换句话说，TS具有相机，并且其输出用于图像生成。因此，TS的几何和光学限制来自摄像头的能力，TS也不能显示实时视频。相反，会员国采取了表格式的办法。在MS的初始化过程中，我们使用色度计制作了一个表格，描述了两个投影仪之间的互补色对。这个预先获取的表格允许我们随时生成互补色图像。至于两台投影仪的几何对齐，我们已经实现了一个用户界面，以实现逐像素的精度。
The main difference between TS and MS lies in the process of synthesizing complementary images. TS needs to generate all the complementary images before you enter the system. This is because TS adopted a camera-based approach. In other words, TS has a camera, and its output is used for the image generation. Consequently, geometrical and optical restrictions of TS come from the camera’s capability, TS also can not display live videos. On the contrary, MS adopted a table-based approach. In the initializing process of MS, we make a table which describes pairs of complementary colors between two projectors, by using a colorimeter. This pre-acquired table allows us to generate complementary color images anytime you want. As for the geometrical alignment of the two projectors, we have implemented a user interface to achieve pixel by pixel accuracy on the floor.
