Abstract:  Because the request of automobile safety is higher and higher, drivers should clearly ensure the surrounding environment of the car, a kind of car surveying technology is proposed. Video mosaicing technology is the basis of surveying technology. In order to meet the requirement of vehicle instantaneity, this paper uses FPGA to achieve the video mosaicing. The system includes video capture module, video pre-processing module, video mosaicing module and video display module. The paper uses Cyclone IV development board of Altera company to complete the system and uses double DDR2 to complete Ping-Pong buffer. We use sift algorithm to match videos and linear fusion algorithm to mosaic videos. The system is verified by experiments and its feasibility is proved.

Key words: field programmable gate array(FPGA),  picture processing, video mosaicing, linear fusion, sift
