【摘要】：隨著社會(huì)發(fā)展，監(jiān)控?cái)z像網(wǎng)絡(luò)日益增多，傳統(tǒng)靠人力排查監(jiān)控視頻不能高效及時(shí)地處理突發(fā)問(wèn)題。如何使得攝像網(wǎng)絡(luò)在安防、智能交通、檢測(cè)生產(chǎn)等領(lǐng)域高效智能工作，對(duì)普通數(shù)字相機(jī)系統(tǒng)提出了巨大的挑戰(zhàn)。依托智能相機(jī)的機(jī)器視覺(jué)算法是一種新型的智能檢測(cè)與識(shí)別手段。當(dāng)今異構(gòu)體系架構(gòu)芯片處理速度不斷發(fā)展，給圖像實(shí)時(shí)檢測(cè)與識(shí)別帶來(lái)了福音。因此，在異構(gòu)體系架構(gòu)上設(shè)計(jì)實(shí)現(xiàn)智能相機(jī)的視頻處理軟件框架，使開(kāi)發(fā)人員在該框架上方便、快速地移植他們期望的機(jī)器視覺(jué)類算法。 本文所述智能相機(jī)異構(gòu)軟件框架工作是基于DVS6467系列嵌入式平臺(tái)，在該平臺(tái)上移植Motorlona公司定制的嵌入式Linux操作系統(tǒng)。在德州儀器（簡(jiǎn)稱Ti）公司提供的軟件開(kāi)發(fā)套件與基本框架基礎(chǔ)上，設(shè)計(jì)與實(shí)現(xiàn)了一套完整的智能相機(jī)視頻處理軟件框架，，并且利用多線程、優(yōu)化等技術(shù)手段充分發(fā)揮異構(gòu)多核處理架構(gòu)的優(yōu)勢(shì)。同時(shí)，為了更為突出體現(xiàn)異構(gòu)處理架構(gòu)的優(yōu)勢(shì)，在Intel-i系列PC上基于QT軟件開(kāi)發(fā)同構(gòu)軟件處理框架，與異構(gòu)處理架構(gòu)形成性能鮮明對(duì)照。 最后，將航拍目標(biāo)識(shí)別算法應(yīng)用在本文設(shè)計(jì)與實(shí)現(xiàn)的智能相機(jī)視頻處理軟件框架上，在智能相機(jī)框架上測(cè)試該識(shí)別算法，其實(shí)驗(yàn)結(jié)果表明本文設(shè)計(jì)與實(shí)現(xiàn)的軟件視頻處理框架方案是可行的、有效的，且具有很好的移植性，方便快速開(kāi)發(fā)機(jī)器視覺(jué)算法。
[Abstract]:With the development of society and the increasing number of video surveillance networks, the traditional manual inspection of surveillance video can not deal with unexpected problems efficiently and timely. How to make the camera network work efficiently and intelligently in the fields of security, intelligent transportation, detection and production, etc. The machine vision algorithm based on intelligent camera is a new method of intelligent detection and recognition. Therefore, a video processing software framework for intelligent cameras is designed based on heterogeneous architecture, which enables developers to transplant their desired machine vision algorithms conveniently and quickly. The heterogeneous software framework of intelligent camera is based on DVS6467 embedded platform. The embedded Linux operating system customized by Motorlona is transplanted on this platform. Based on the software development suite and basic framework provided by Texas Instruments, a complete video processing software framework for intelligent camera is designed and implemented. At the same time, in order to give full play to the advantages of heterogeneous multi-core processing architecture, the isomorphic software processing framework is developed on Intel-i series PC based on QT software. Performance contrasts with heterogeneous processing architecture. Finally, the aerial target recognition algorithm is applied to the video processing software framework of intelligent camera designed and implemented in this paper, and the recognition algorithm is tested on the frame of intelligent camera. The experimental results show that the software video processing framework designed and implemented in this paper is feasible, effective, and has good portability, and it is convenient to develop machine vision algorithm quickly.
