摘要

本篇研究目的為複雜場景下建構完整背景。除了利用背景相減偵測移動物體，本系統也可以應用於風景區、街景的背景重建。
本研究背景重建可分為三個步驟。首先，利用隨機影像相減法選出多個群組，將這些群組進行分類後可以得到後補背景。接著本研究利用背景更新來提高後補背景準確率。最後，針對動態背景進行處理，建構正確的影像背景。
實驗結果證明，本研究方法可以在複雜場景下建構出完整的背景。

The purpose of the study is to construct a comprehensive background in complex scenes. This comprehensive system not only can utilize background subtraction to detect moving objects, the background of scenic and street view can also be constructed.
The background reconstruction of the research can be divided into three steps. First, alternate background can be obtained by classifying groups which are selected using random image subtraction. Next, use the background updating technique to increase alternate background accuracy.
Finally, focus on the dynamic background and process it in order to construct the correct image background.
The experiment results showed the research can construct a complete background in complex scenes.
