中文摘要 | 本文主要探討影像感測技術於邊坡運動監測之適用性,藉由低成本、高解析度攝影機即時記錄邊坡滑動、傾倒及流動等過程,並以絕對差值分析法搭配門檻值評估邊坡地表運動過程。物理模型感測結果顯示,採用影像感測技術可即時偵測邊坡張裂隙發展、岩體變形與地表瞬間崩壞之區位,有效提升災前及災中預警之成效。實際山崩案例分析發現,順向坡滑動之感測特徵由初始傾斜長條型紅色區塊逐漸增加範圍,最終塊體於地面擴散後將造成紅色區塊瞬間擴大。而影像感測技術對於土石流速度及流動狀況之監測,亦可作為下游保全對象防災疏散之參考。此外,本研究亦初步歸納影像感測技術之應用限制,期能作為未來邊坡地表變動監測與相關研究之參考。 |
英文摘要 | This study primarily investigates the applicability of video motion detection (VMD) technology for detecting side-slope movement. This technology involves using an economical high-resolution camera to instantly record activities, such as side-slope sliding, toppling, and movement. Concurrently, sum of absolute differences (SAD) analysis was combined with the threshold value to assess the side-slope surface movement. The physical modeling detection results showed that the VMD technology instantly detects side-slope tension crack development, rock deformation, and the location of collapsing surfaces, thereby effectively improving the effectiveness of alarms before and during disasters. Actual landslide case analysis shows that dip-slope movement is detected through gradual expansion of initial slanted rectangular red blocks and instant magnification following the block expansion on the ground level. The monitoring mechanism of VDM technology for detecting the speed and movement of debris flow can be used as a reference in disaster prevention and evacuations of people living in downstream areas. Furthermore, this study generalizes the limitations of VMD technology. These generalizations can be used as a reference for future slope surface movement monitoring and related studies. |
