Abstract:

In order to efficiently improve the image definition and resolution of multi-screen splicing display system in video supervision,a real-time video image processing algorithm based on FPGA is proposed.Firstly,the overall structure of the system and video image cache and image segmentation in FPGA module are introduced.Then the bilinear interpolation algorithm is presented according to video display requirements.Simulation by ModelSim shows that the algorithm does conform to the requirements of multi-screen splicing display system.

Key words: video supervision;video image processing;bilinear interpolation algorithm;FPGA;multi screen
