近景攝影測量雲端服務系統開發與應用－－以公路邊坡為例

Research on Development and Application of Close-range Photogrammetry Cloud Service System - Taking Highway Slope as an Example

臺灣位於歐亞板塊和菲律賓海板塊的聚合邊界，多山、地質年輕破碎且地震頻繁，加上東北季風與西南氣流及夏季颱風影響，常於瞬間豪大雨過後引發邊坡崩塌，進而造成道路阻斷或人車傷損。為維持公路邊坡安全，公路管理機關需依交通部頒「公路邊坡大地工程設施維護與管理規範」規定針對所轄邊坡進行各項巡檢作業，惟實務上，由於邊坡範圍廣泛且地形起伏劇烈，因此相關巡檢作業除需投入大量人力，巡檢結果亦不易量化呈現，整體性亦有所不足。本研究開發近景攝影量測雲端服務系統以擴大運用成效。系統提供使用者於公路邊坡巡檢作業時，可藉由手持或無人飛行載具酬載相機等方式來獲取道路邊坡監測區域影像，再經由上傳影像至系統來進行全自動三維化服務，於成果上提供監測點分析、比對、查詢及展示功能，提供簡易來量化記錄邊坡表面資料，輔助以目視為主之巡檢作業的不足，提升巡檢及管理效能。

Taiwan is located at the aggregation boundary of the Eurasian plate and the Philippine Sea plate. It is mountainous, geologically young and has frequent earthquakes and the influence of the northeast monsoon and the southwesterly airstream and the summer typhoon, it often causes the slope to collapse after the sudden heavy rain, which in turn causes road blockage or human car damage. In order to maintain the safety of the highway slope, the highway management agency shall, in accordance with the provisions of the“Regulations for the Maintenance and Management of Highway Slope Land Engineering Facilities”issued by the Ministry of Communications, carry out various inspections on the road slopes managed by them. However, in practice, due to the wide range of slopes and the undulating terrain, the relevant inspection operations require a large amount of manpower, and the inspection results are not easy to quantify, and the overall performance is also insufficient. This study develops a close-range photogrammetric cloud service system to expand the application effect. The system provides users with the ability to obtain the image of the roadside slope monitoring area by means of a handheld or UAV payload camera, and then upload the image to the system for automatic three-dimensional service. Provide monitoring point analysis, comparison, query and display functions, provide simple to quantify the surface data of the slope, assist the visual inspection as the main deficiencies of the inspection, and improve inspection and management efficiency.
