傾斜航空攝影測量作為近年來國際上發展十分迅速的一項高新技術，能夠獲取真實世界的三維場景資訊，是對傳統航空攝影測量技術的補充，為航空遙測領域提供了一種新的資料來源。本研究針對傾斜攝影，使用六旋翼型UAS搭載本團隊自行開發設計的多相機系統。其多相機雲台共搭載5部相機，測試多相機雲台進行傾斜影像三維重建的流程。並比較多相機系統拍攝不同傾斜影像與傳統垂直影像，以及使用不同航向與僅使用單一航向垂直加傾斜同步拍攝之不同角度影像製作三維重建模型之效果差異，最後並提出建議。

In recent years, oblique photography has rapidly developed as an advanced technique which can easily acquire 3D panoramic data. It is a supplement to traditional aerial photography to provide a new source of information to the field of remote sensing. In this study, the GR6 Multi-Rotor UAS is used for oblique photogrammetry and is equipped with a gimbal, which was developed by our team, designed to carry cameras. The cameras are tested to carry out the procedures of oblique photography to generate their 3D urban landscape reconstruction and compare the results different oblique photos with traditional orthogonal photos. This is done to compare the discrepancies caused by the effect of the different directions of the angles in both the oblique photos and the vertical angle of the orthogonal photos from a single flight. At last, recommendations should be made.
