摘要
为了使得跟踪算法中能够抗图像旋转,采用FPGA对模板图像进行任意角度旋转的预处理,产生满足图像匹配所需要的多种旋转模板。在FPGA上实现旋转算法,完成对模板图的任意角度旋转,重点研究了该旋转系统的硬件框架和软件框架,并在Altera公司的CycloneIII系列FPGA硬件平台对该算法进行了功能和时间测试。该设计达到实时性要求,为整个跟踪系统提供了多种旋转模板,实现了跟踪算法抗旋转性。
In order to resist image rotation in tracking arithmetic, the paper adopts FPGA to circumrotate any angle for templet＇s image and produces some roiling templet image for image matching. Inverted rotation algorithm based on FPGA is realized to accomplish any angle of rotation for templet＇ s image, it is the importance of researching hardware＇ s architecture and software＇ s architecture. Function and time testing, matching consequential verifi- cation are based on the hardware platform of FPGA. The designing meets the demands of timeliness in order to supply some templets for resisting image rotation in tracking system.
