摘要：本文主要介紹了一套實(shí)時(shí)圖像全景拼接系統(tǒng).該系統(tǒng)以研祥公司推出的EC5-1719CLDNA嵌入式開(kāi)發(fā)板為基礎(chǔ)平臺(tái)，基于WinXP操作系統(tǒng)，通過(guò)視頻采集卡采集CMOS攝像頭攝取的外界數(shù)據(jù)，采用SIFT核心算法來(lái)實(shí)現(xiàn)對(duì)周圍環(huán)境的實(shí)時(shí)全景拼接功能.整個(gè)軟件部分采用了多線程的技術(shù)，并且運(yùn)用了Intel提供的優(yōu)化工具進(jìn)行優(yōu)化，使核心功能達(dá)到實(shí)時(shí)的效果；同時(shí)通過(guò)無(wú)線網(wǎng)卡，平臺(tái)還可以實(shí)現(xiàn)將拼接好的視頻以無(wú)線的方式傳給客戶終端.整體功能強(qiáng)大，界面友好，車載的定位使得系統(tǒng)具有更加機(jī)動(dòng)靈活的特點(diǎn).
Abstract: A set of real-time image panoramic stitching system is introduced in this paper. The system is mainly supported by embedded technology .In our design,a X86 based platform which is supplied by EVOC Company and equiped with windows XP proffesional OS is needed.First, pictures are got with video capture card and CMOS cameras.Then,the pictures are processed by SIFT core algorithms.At last,all pictures are perfectly stitched in one panorama.Compared with traditional solution, parallel program and multi-threaded technology optimized by Intel® VTune™ Performance Analyzer is adopted.Through the system,real-time video can be seen on a client terminal .Images are transported through wireless network card fluently because of JPEG-compressing.It can be carried easily by Vehicles.
