摘要

無人飛行載具的應用漸廣，可從空中以不接觸物體之方式蒐集地表影像資料，並可加以處理分析、判釋，作為了解地面目標物之特性及地表地形資訊，配合地理資訊系統、導航系統後，可快速獲取解析度高的影像及建置高精度數值地形模型。定翼及旋翼無人飛行載具雖然成像原理大致相同，但較少就其拼接控制點的布設方式進行探討。本研究以屏東科技大學後山為樣區進行航拍，發現無論是定翼機或旋翼機只要控制點選擇足夠其精度均可達到一般規劃設計使用標準，經進一步比較後發現定翼機的航拍精度高出旋翼機數倍之多。因此若操作更為熟練且控制得宜，對於坡地長時間週期性較大位移變動的量測應更為便利及可靠。

The application of unmanned aerial vehicles is becoming more and more widespread. It can collect surface image data from the air by contacting with objects, and can analyze and interpret them. It can be used to interpret the characteristics of ground targets and surface terrain information. After the system, you can quickly obtain high-resolution images and build high-value terrain models. Although the fixed wing and rotary wing unmanned aerial vehicle have the same imaging principle, the arrangement of the splicing control points is rarely discussed. This research uses Pingtung University of Science and Technology as a sample area to conduct aerial photography. It is found that whether the fixed wing or rotary wing aircraft has sufficient control points, its accuracy can meet the general planning and design standards. After further comparison, the aerial accuracy of the fixed wing aircraft is several times higher than that of the rotorcraft. Therefore, if the operation is more skilled and the control is appropriate, the measurement of large-scale periodic displacement changes over a long period of time on the slope should be more convenient and reliable.
