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。
Take two pieces of digital signal processor TMS320C6203B that TI Company produces as the core, use the programmable logic array CPLD to carry on the logic control, adopt the field programmable gate array FPGA to make the pretreatment of the picture and carry on the double digital signal processor (DSP) Communication, real-time related image processing. The real-time performance of this system is good, and the gray characteristic of digital image can be used directly. The drift of target tracking point is small under low signal-to-noise ratio. Target tracking can adapt to the background of different gray distribution.
