We present a software-hardware cooperative method for multi-projector seamless tiled display system, and it mainly consists of two steps. Firstly, an ordinary PC (Personal Computer) is used to preprocess the display system with software. Secondly, one or more hardware image processors, which are based on FPGAs (Field Programmable Gate Arrays), are used to process the source video image without the aid of computers. And an optimized algorithm is used in the method. Experimental results show that the proposed method is effective and of low cost and high performance.
