| 摘要: | 傳統建築物外觀與室內測繪多採用人工測繪與光學測繪等方法。因其外業測量與內業作業時間較長，精度較低等問題，近年來業界引進三維雷射影像掃瞄儀器，縮短測繪時間，將掃瞄數據輸入電腦進行後續分析、比較，工作效率提升，達到事半功倍的效果，然而三維新儀器功能眾多、操作過程繁瑣，有必要建立其標準作業程序。
本研究以美國三維雷射掃瞄儀器FARO Photon 120系統，依儀器單元架構組立、儀器架設位置、儀器掃瞄方法與步驟、掃瞄點雲資料存取處理、軟體建置、點雲建構圖像程序、圖像色彩處理等程序，建立FARO Photon 120系統標準作業程序，應用於建置市定古蹟松山菸廠五號倉庫建築點雲資料。
由本研究建立FARO Photon 120系統標準作業程序，包括前置作業 (儀器諸元、儀器設置作業)、掃瞄作業(現場掃瞄作業流程、儀器組裝流程)及後製軟體設置作業(後製軟體設定、參考點接合方式、後製軟體操作步驟、雜點處理及建模與圖型轉換)，內容考慮不同掃瞄精度、架設高度、距離、方位、測點多寡及儀器與被測物之間是否有東西阻擋的掃瞄結果，經由後製軟體評估點雲密度的差異性，以降低掃瞄誤差，減少掃瞄次數，提高掃瞄精度準確性，以此標準作業程序獲得市定古蹟松山菸廠五號倉庫建築物三維外觀與四方向數位立面圖像。此研究結果可供FARO Photon 120系統應用於三維測量科技業界之參考。
Most of the external and interior surveying of traditional building are used for the artificial and optical measurement methods, It needs more measure time to taking external and internal work, and impact with low precision. In recent year, 3D Light Detection And Ranging (it also call LIDAR) surveying system can cut down the surveying and mapping time, compare with the data scan from the 3D system input to the computer backward analysis, 3D system has highly work efficiency. But new 3D instruments have more instrument functions and complex operation procedure, it require for establish standard operating procedures of 3D surveying system.
In this research, we use FARO Photon 120 system(from the U.S.A.) as the SOP object, The SOP of FARO Photon 120 system include the contains of instrument unit, the instrument setup location, the instrument scan method and procedure, the scan point cloud data reservation processing, the software installation, the procedure of point cloud mapping, and the chromatics of the image processing program. All the contains transfer to establish the FARO Photon 120 system of standard operating procedures, Applied to setup the 3D image of Song-Shan Tobacco Factory No.5 Warehouse Historic Building.
As the result, the FARO Photon 120 system standard operating procedures include instrument setup pre-operation, scanning operations and backward software setup operations should consider the different scanning accuracy, and erected height and distant of instrument, amplitude, and the amount of measurement points and instrumentation and whether there is something countercheck the scan results between the measured object, through backward software evaluation point cloud density differences, in order to reduce scanning difference, lower the scan number of times, improve the precision of the scanning accuracy, this standard operating procedures 3D appearance, we can get four side elevation, and eight digital image diagram of the Song-Shan Tobacco Factory No.5 warehouse building. The results of this study, Set up the available document of the FARO Photon 120 system measuring technology to the other users. |
