車載實(shí)時圖像全景拼接系統(tǒng)

摘要：本文主要介紹了一套實(shí)時圖像全景拼接系統(tǒng).該系統(tǒng)以研祥公司推出的EC5-1719CLDNA嵌入式開發(fā)板為基礎(chǔ)平臺，基于WinXP操作系統(tǒng)，通過視頻采集卡采集CMOS攝像頭攝取的外界數(shù)據(jù)，采用SIFT核心算法來實(shí)現(xiàn)對周圍環(huán)境的實(shí)時全景拼接功能.整個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)時的效果；同時通過無線網(wǎng)卡，平臺還可以實(shí)現(xiàn)將拼接好的視頻以無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.
