基于Camera Link接口的图像跟踪系统的设计与实现

为了提高图像跟踪对小目标的跟踪精度,采用高帧频和高分辨率的数字相机作为输入。系统采用以DSP和FPGA以及大容量缓存的硬件架构,通过FPGA的逻辑编程灵活调配系统的资源,将图像采集、图像预处理、图像跟踪、图像显示等功能合理分配至各个硬件单元。经实验验证,各个功能单元达到预期效果。这里介绍的基于Carema Link接口的图像跟踪系统,其显著特点在于图像处理能力强,跟踪精度高。

Image Tracking System Design and Realization Based on the Interface of Camera Link

A digital camera of high frame frequency and high distinguish character is used for improving the precision of tracking little target.The system uses a hardware framework including DSP and FPGA and mass buffer storage,resource of the system is flexibly assigned through the logic programming of FPGA.The image acquistion,pretreatment,tracking and displaying function are reasonable distributed to each hardware unit.The effect of each function unit is anticipated through experiment testing.The tracking system based on the interface of Camera Link which is introduced in this paper has distinct character of strong processing power and high precision of tracking.
