以電腦視覺技術建構之停車場管理服務

Vision-Based Parking Lot Surveillance Services

摘要


本論文提出一個以電腦視覺技術建構停車場管理服務之架構,其結合多攝影機空間定位與協同追蹤技術,進行畫面內停車格區域與移動車輛之偵測,再根據車輛偵測的結果進行軌跡追蹤與紀錄。此架構具有多項顯著的優點:(1)具備將多攝影機影像轉換疊合成為全域影像之能力,去除單攝影機影像視角之限制;(2)使用高斯混合模型建立停車場背景模型,有效減低畫面內光影變化所造成的干擾。同時,本文更利用先進的特徵點對應技術(SIFT)與有效點選取技術(RANSAC),探討全自動化停車場管理服務開發的可能性與限制。

並列摘要


A vision-based parking lot surveillance framework is proposed in this paper. This framework utilizes multi-camera localization and tracking technologies to detect parking spaces and moving cars. The detected results are then used to estimate robust car moving trajectories for surveillance related event analysis and data queries. There are two main contributions of this framework-(1) it transforms each image from different cameras onto a global-view image that maximizes the field-of-view of the multiple cameras; (2) it utilizes Gaussian-Mixture-Model (GMM) to build a parking lot background model which is resistant to illumination variations. Moreover, this article also explored the possibility to build the system automatically through the use of the Scale Invariant Feature Transform (SIFT) and RANdom SAmpling Consensus (RANSAC) algorithms.
