無人機傾斜攝影量測及3D虛擬實境建構之飛行參數分析研究

傾斜攝影技術已被歐美國家應用於災難或戰場指揮、安全防衛系統建構、城市規劃管理、房產買賣評價鑑定等行業，是一項新興的技術，本研究中以三維空間之測量技術，應用於航空傾斜攝中，其中以四旋翼之飛行載具（DJI Phantom 4 Pro V2.0）為傾斜攝影載台，搭載高解析相機對地拍攝傾斜影像，影像採集完成後，以smart3D執行3D影像合成及建模，並導入虛擬實境之建構，研究著重二個重點，其一，以傾斜攝影測繪的航線參數研究，建立傾斜攝影測繪3D模型分析模式，其中飛行航線以雙格錙字形航線及環形航線為主，如飛行高度及拍攝傾斜角等參數，分析各航線優缺點，找出優化航線據以合成3D影像及建立測繪數據庫，其二，在完成傾斜影像後製後，將實景與虛擬的3D影像組合，在虛擬環境3D平臺中，建構了戰場及工業重劃區兩個虛擬實境，其中戰場虛擬實境，除了進行戰場空間評估分析外，進一歩應用3D列印技術，建立戰場3D模型；在工業重劃區虛擬環境案例中，有效測繪工業區之重要設施尺度，成功地整合未來廠房建築情境，研究結果，除可供操作人員做為參考外，更可使高階領導人員，快速瞭解環境現況，做為重要決策之參考。

Oblique photography technology has been used in disaster or battlefield command, security defense system construction, urban planning management, real estate sales evaluation and identification in European and American countries. It is a novel technology. the research architecture uses the quad-rotor DJI Phantom 4 Pro V2.0 as the Oblique photography platform, Equipped with a high-resolution camera. To capture oblique images on the ground. After the image capture is completed, then use smart3D to execute 3D image synthesis and modeling, and construction of virtual reality. This paper focuses on two key points. One is to study the flight path parameters of oblique photography mapping targets and establish a 3D model analysis mode for oblique photography mapping. The flight path of double grids and circular are the main flight parameters, such as flight altitude and capture images angle, and find the best image synthesis parameters, parameterize the flight path of oblique photography mapping, analyze the advantages and disadvantages of each flight path, and find out the optimized flight path data To synthesize 3D images and establish a surveying and mapping database. Second, after finishing the oblique image post-production, the real scene and virtual 3D images are combined to construct two virtual realities of the battlefield and the industrial rezone on the 3D platform of the immersive virtual environment. In the virtual reality of the battlefield case, the battlefield space is evaluated and analyzed, and 3D printing technology is used to build a 3D model of the battlefield. In the virtual environment of the industrial rezoning zone case, the scale of important facilities in the industrial zone is effectively surveyed, and the future factory buildings are successfully integrated In the architectural context, the results of this study can provide high-level decision-makers with a quick understanding of the current environment and serve as a reference for important decisions
