Automotive Multi-sensor Real-time Image Tracking System Hardware Design

With the development of the image processing technology and the emergence of new multimedia DSP devices for special purpose, image tracking systems are turning into a new generation. Taking a lot of literatures and relevant projects for reference, the thesis proposes a brand-new design solution to construct a image tracking system platform based on TMS320DM642, which is a high-performance multimedia digital signal processor developed by TI.The thesis focuses on the analysis and the design of the image tracking system based on DM642. Taking the functions and the quotas of the system into account, we design the hardware and the software of the system, mainly the hardware.Firstly, the thesis introduces the background of the project and the value of the research, summarizes the development, current situation and the tendency of object image tracking system. Secondly, focusing on the functions of the system, the thesis discusses the main plan of the system design, and finishes the design of the main structure of the system. Then, the hardware design of the modules in the system is narrated in detail, including the introduction of DM642, the design of the expanded mass memory SDRAM circuit, the image acquisition and output modules, the power system and the clock system etc. Adopting the modular design technique, the system has better expansibility. For PCB design, considering the SI (Signal Integrity) and EMC (Electro-Magnetic Compatibility), the PCB design strictly follows the rules of high speed circuit design. In software design, the software flow of the whole system is analyzed, including the flow of each molecule in detail.Finally, a summary of the project is made, the process of the project is introduced, and further proposals and additional functions of the design are given at last.
