Design For DZ Image Sequence Compression System

Missile terminal guidance technology becomes more and more important in militarystruggle. Real-time high-performance compression and transmission of the image sequencesin the terminal guidance is one key technology of the missile telemetry system and has greatsignificance for the missile to finish the combat mission. Since the particularity of theapplication environment, the current image/video compression methods cannot satisfy thepresent requirements of real-time and definite proportion compression in the missileterminal guidance. The research of high speed and real-time image compression systemwhich is suitable for the missile terminal guidance has great engineering significance.The missile telemetry cabin has small dimension and limited number of transmissionchannels, and has strict restriction on the power of the telemetry equipments. Thecorresponding compression method must have the characteristics of simple algorithm, highcompression ratio and low power. Meanwhile the duration of the image sequences in theterminal guidance is very short, so the error in the compression process is not allowable.Above all, the JPEG2000compression is finally selected to obtain high-performance anddefinite proportion compressed stream, and the error propagation is not exist.This thesis achieves the design and realization of the compression system of imagesequences for the missile terminal guidance. One FPGA is selected as the main control chipand the input signals are using the LVDS level standard to obtain high speed transmissionperformance. The JPEG2000encoding function is realized with one single chip ADV202.The final system can meet the requirements of the real-time compression of the imagesequences in the terminal guidance.
