| 摘 要： | 以两片由TI公司生产的数字信号处理器TMS320C6203B为核心,用可编程逻辑阵列CPLD进行逻辑控制,采用现场可编程门阵列FPGA作图像的预处理和进行双数字信号处理器(DSP)之间的通讯,实现了实时相关的图像处理。此系统实时性好,可直接利用数字图像的灰度特征,在低信噪比的情况下目标跟踪点漂移小,目标跟踪能够较好地适应不同灰度分布的背景。

| Abstract: | The real_time image processing system based on the edge correlation arithmetic is proposed. In this system,double TMS320C6203B of TI Company is used as the core processor, and the programmable logical array(CPLD) is applied for logical controlling, and the field programmable gate array (FPGA) is used for image preprocessing and communication between two DSPs. In the correlation tracking arithmetic, the eight_direction Soble operator is used for improving performance of edge extraction, and the correlation funtion is optimized. This system has some advantages, such as the processing is real_time, and grayscale characters of image are used directly, and the excursion of tracking point is little, and could be applied to object tracking in various background. |
