【摘要】：隨著社會公共安全需求的提高,視頻監(jiān)控正不斷延伸到社會的各個角落,傳統(tǒng)的人工值守的視頻監(jiān)控的方式已經(jīng)不能滿足日益增長的監(jiān)控需求和監(jiān)控規(guī)模的需要。以全天候、無人值守、自動告警、實(shí)時等智能化為特點(diǎn)的智能監(jiān)控的需求變得越來越迫切,因此,對智能視頻監(jiān)控技術(shù)的研究成為了視頻監(jiān)控領(lǐng)域中一個研究熱點(diǎn)。 本文在研究智能視頻監(jiān)控的各種關(guān)鍵技術(shù),對現(xiàn)有的各項(xiàng)研究成果和應(yīng)用實(shí)例進(jìn)行分析研究的基礎(chǔ)上,構(gòu)建了基于DSP的智能視頻分析前端系統(tǒng),與網(wǎng)絡(luò)視頻服務(wù)器和監(jiān)控終端一起,建立了一個完整的智能視頻監(jiān)控系統(tǒng)。 智能視頻監(jiān)控關(guān)鍵技術(shù)的研究和實(shí)現(xiàn)基于ADSP-BF561的智能視頻分析前端是本文的研究重點(diǎn)。本文首先對智能視頻監(jiān)控關(guān)鍵技術(shù)進(jìn)行了研究,包括運(yùn)動目標(biāo)檢測技術(shù)、運(yùn)動目標(biāo)跟蹤技術(shù)以及各種計(jì)算機(jī)圖像圖形處理算法。對智能視頻監(jiān)控關(guān)鍵技術(shù)的研究為構(gòu)建智能視頻監(jiān)控系統(tǒng)提供了良好的理論基礎(chǔ),并且為各項(xiàng)功能的實(shí)現(xiàn)提出了技術(shù)解決路線。構(gòu)建基于ADSP-BF561的智能視頻分析前端是本文的另一個研究重點(diǎn),課題針對BF561的雙核特性采用了雙核應(yīng)用模式構(gòu)建工程,結(jié)合開源軟件工具庫,實(shí)現(xiàn)了視頻H.264編碼和視頻分析的并行工作。工程包括視頻數(shù)據(jù)采集、智能視頻分析、視頻H.264編碼以及壓縮碼流的傳輸?shù)裙δ苣K,實(shí)現(xiàn)了入侵檢測,遺留物檢測,運(yùn)動目標(biāo)跟蹤,信號丟失檢測等眾多功能。最后針對DSP對工程進(jìn)行了優(yōu)化,以提高處理效率,達(dá)到實(shí)時性要求。
[Abstract]:With the improvement of social public security demand, video surveillance is extending to every corner of the society. The traditional manual video surveillance can not meet the increasing demand for surveillance and the need of monitoring scale. The demand of intelligent surveillance, which is characterized by all-weather, unattended, automatic alarm, real-time and so on, has become more and more urgent. Therefore, the research of intelligent video surveillance technology has become a research hotspot in the field of video surveillance. Based on the research of various key technologies of intelligent video surveillance and the analysis of existing research results and application examples, the intelligent video analysis front-end system based on DSP is constructed in this paper. Together with the network video server and the monitoring terminal, a complete intelligent video monitoring system is established. Research and implementation of key Technologies of Intelligent Video Surveillance the research focus of this paper is intelligent video analysis front end based on ADSP-BF561. In this paper, the key technologies of intelligent video surveillance are studied, including moving target detection, moving target tracking and various image processing algorithms. The research on the key technology of intelligent video surveillance provides a good theoretical basis for the construction of intelligent video surveillance system, and provides a technical solution for the realization of various functions. The construction of intelligent video analysis front end based on ADSP-BF561 is another research focus of this paper. In view of the dual-core characteristic of BF561, the paper adopts dual-core application mode to build the project, and combines with open source software tool library. The parallel work of video H.264 coding and video analysis is realized. The project includes video data acquisition, intelligent video analysis, video H.264 coding and the transmission of compressed code stream. It realizes many functions such as intrusion detection, legacy detection, moving target tracking, signal loss detection and so on. Finally, the project is optimized for DSP to improve the processing efficiency and meet the real-time requirements.
