| 中文摘要 | 在空載光達產製數值高程模型與數值表面模型之過程中,所有的步驟皆會影響最終產品品質。在不同階段採用不同之檢驗標準,或採用不同工序,使用者可依用途選擇適合之產品。本研究僅以空載光達產製點雲之作業為探討對象,整理現有之作業流程,並針對一般使用目的之作業流程設計查核項目和時機,以為品質管制之手段。本研究將空載光達作業流程分為任務規劃、資料獲取和資料處理,其中資料處理又分為點雲解算和點雲分類與編修。依據流程,本研究擬定九個查核點,以供品質檢驗時之參考。 |
| 英文摘要 | Each element in the production chain of airborne lidar operation will inevitably influence the final quality of the product. By selecting different parameter values in each check item, and adopting different procedures, one can define the quality level of the product required for the application. This study investigates the production flow of airborne lidar for the digital elevation model and digital surface model. The procedures and different phases of the operation are analyzed. A series of check items for quality assurance and their schedule are proposed. Three phases are identified, mission planning, data collection, and data processing. In the data processing, it is further divided into point cloud generation, classification, and editing. |
