Bibliography:In view of two-channel video image superimposed fusion,an flexible and high real time hardware system based on FPGA is designed and implemented.The system can adjust proportion of size and location of the video image superimposed fusion arbitrarily based on the actual need.With the technique of bilinear interpolation scaling algorithm,DDR2 storage, superimposed fusion algorithm and so on, the scheme is implemented on FPGA hardware platform after simulated and validated.The result indicates that the system can achieve the desired effect,and the effect of superimposed fusion picture is good and can meet the needs of engineering applications.
