Abstract: To solve the problems of inefficiency, high cost and long time-consuming in rural house measurement, this paper uses UAV tilt photogrammetry technology to accurately survey real estate. First, UAV tilt photography is used to obtain images from different angles, and a real-life three-dimensional model is built. Then, CASS3D software is used to collect indoor data on the three-dimensional model, and the results of the integrated map of the premises and buildings are obtained. The accuracy of tilt photography results is analyzed through the medium errors of checkpoints and boundary lines. The results show that the UAV tilt photogrammetry technology can fully meet the technical specifications, and the data results have high accuracy, effectively improve work efficiency and quality, and shorten the project production cycle.

傾斜攝影測量技術(shù)是利用傾斜攝影機和相應的處理軟件來獲取和處理傾斜攝影的方法[1]。相比于傳統(tǒng)的垂直攝影測量技術(shù),傾斜攝影測量技術(shù)能夠提供更加真實、細致和高分辨率的三維地理信息。其通過將相機傾斜安裝在飛行器或地面車輛上,以不同角度拍攝目標區(qū)域,從而得到傾斜的影像數(shù)據(jù)。通過利用同一相機不同位置拍攝的影像、匹配特征點或特定的控制點,進行影像的定位和定向傾斜攝影測量技術(shù)的原理主要涉及2個方面:相對定向和絕對定向。相對定向是指在攝影測量過程中定向。絕對定向是指將傾斜影像與地理坐標系統(tǒng)進行對齊,確定影像中各個目標的地理位置。
傾斜攝影測量技術(shù)需要傾斜攝影機、導航系統(tǒng)和數(shù)據(jù)處理軟件等關(guān)鍵設(shè)備和工具的支持。……
