Design Of Electronic Stabilization System For Video Images Based On FPGA

Electronic image stabilization technology is a video image sequence stabilized technique, it makes use of the image information to detect the displacement vector of the image, and then through motion compensation to obtain a clear and stable video sequence. It is widely used in military and civilian fields.In this dissertation, the basic principles for electronic image stabilization and the commonly used image stabilization algorithms are introduced, and but only details the implementation process, the advantages and disadvantages of gray projection algorithm, bit plane matching algorithm, the representative point matching algorithm and feature point matching algorithm, and also briefly summarize the motion compensation methods.The dissertation focuses on the implementation of the electronic image stabilization system on the FPGA development platform, and the system can be divided into four modules: video capture, video caching, video stabilization and video output. In this system, the problems that how to synchronize the cross-clock, to cache the large amount of video sequences, to implement the motion estimation and motion compensation on the FPGA development platform have been solved. According to the RTL schematic of image stabilization system simulated by ISE, the article details the implementation of each module on the FPGA platform, and details these synthesis and simulation results.In this dissertation, the electronic image stabilization system is designed in the platform of Seed Fem025, using ISE to synthesize and simulate the design, and make use of Verilog HDL to describe the system architecture, and synthesis and simulation for each module has been done. This dissertation finished the system function verification.
