基於即時安全防盜系統實作硬體移動物體偵測

Abstract

在電腦視覺中，移動偵測(motion detection)為一大探討重點，它可運用在很多方面。由於移動偵測系統的計算量大，對於講求即時(real-time)的系統中，若以軟體型式加入移動偵測演算法後，往往偵測到的影像無法即時傳送到監視器，造成偵測與觀察不同步的情形，因此在本文中提出了以硬體來實作移動物體偵測以加速並達到即時系統之需求，本文將分別對移動物體偵測在以純軟體實作、以純硬體實作來做討論，並分析個別的效能。本文也對於移動偵測以軟硬體共同設計下之效能做分析，進而探討即時移動偵測系統以何種方式實作為最佳。

Among computer visions, motion detection which can be applied to many areas would be quite critical for research. Due to the large amount of computations of a motion detection system, it’s such often a circumstance that if the software form is utilized to motion detection operations, the images detected couldn’t meet the real-time requirements of a surveillance system , leading to asynchronous condition between detection and observation. Consequently, in this research, we take advantage of specific hardware to approach motion detection in order to accelerate and to meet the need of real-time surveillance systems. In this research, we’re going to discuss motion detection in fully software and in fully hardware respectively, and then analyze their efficacy. We also evaluate the frame rate of motion detection in hardware/software co-design in the thesis.
