基于雙DSP平臺(tái)的實(shí)時(shí)跟蹤系統(tǒng)設(shè)計(jì)

本文以兩片定點(diǎn)DSP TMS320C6203 為核心，設(shè)計(jì)了一個(gè)用于處理1024×1024 大小圖像（12 位數(shù)字相機(jī)）的電視跟蹤系統(tǒng)，并對(duì)系統(tǒng)的硬件設(shè)計(jì)和軟件設(shè)計(jì)分別進(jìn)行了詳細(xì)介紹。對(duì)實(shí)時(shí)圖像序列進(jìn)行預(yù)處理后，DSP1 進(jìn)行捕獲和圖像增強(qiáng)、顯示，DSP2 用于實(shí)時(shí)
跟蹤。主要解決了兩個(gè)關(guān)鍵問題：第一， 采用分段投影的方法，解決了對(duì)于大圖像大數(shù)據(jù)量的目標(biāo)全屏捕獲問題，并滿足實(shí)時(shí)要求；第二，根據(jù)目標(biāo)大小動(dòng)態(tài)調(diào)節(jié)跟蹤窗，對(duì)目標(biāo)進(jìn)行實(shí)時(shí)跟蹤。實(shí)驗(yàn)表明系統(tǒng)對(duì)目標(biāo)的實(shí)時(shí)跟蹤有很好的性能。

Abstract: In order to meet the requirement of the real-time video tracking System, we can utilize the embedded double DSPs to assign multi-task efficiently and reduce the processing time. This paper also resolved two key problem: first, in order to capture the target in the huge video image(1024*1024), we use the projection method group by group; second, the tracking window can be adjusted according to the size of the object. The examination proved the tracking system works well and all the purpose can be reached.
