The Sopc-based Moving Target Detection And Tracking System

In recent years, video and image processing typically require very high computational power. Given the increasing processing demands, the parallel processing capabilities of programmable logic devices make them an attractive implementation option for highly repetitive task found in video and imaging functions. In the field of real-time video surveillance, SOPC(System On a Programmable Chip), which is acknowledged as a greatly valuable technology, has a wide application in moving object detection and tracking.In this dissertation, a moving object detection and tracking system based on SOPC is designed. SOPC is an embedded programmable on-chip system, which is achieved the function of microprocessor in FPGA. Instead of using multiple programmable digital signal processors, a single FPGA with an embedded Nios II processor can deliver the requisite level of computing power more cost-effectively, while simplifying board complexity.Main work of this dissertation includes:(1) Built the hardware and software platforms;(2) Configurated the decoder chip by I2C bus controller, which transfers the PAL standard voltage signals into standard decoder YCbCr4: 2:2 digital signals;(3) Detected moving target by hardware device;(4) Transfered video signals into a format of signals that supported by VGA monitor;(5) TransplantedμClinux operating system, which is prepared for the long-distance network transmission as the ulterior design;(6) Tracked the moving target by the software device.The researching contents and realizing methods in the thesis have laid a stable foundation for the ulterior design of the long-distance network transmission and intelligentized monitor in the future.
