【摘要】 以旋翼无人机在小范围大比例尺(1∶500)地形图测绘中的应用为研究目的,选用市场上4种不同厂家、不同型号的旋翼无人机,对同一试验区进行倾斜摄影测量,并对其线划图成果的数学精度进行评定,同时对精度的影响因素进行初步探讨。通过分析,初步验证旋翼无人机倾斜摄影测量技术应用于1∶500大比例尺地形图测绘的可行性。更多还原

【Abstract】 This study aims to explore the application of rotor UAV in small area large-scale( 1 ∶ 500) topographic surveying and mapping. Four rotor UAV of different manufacturers and different types are chosen from the market to survey same test area based on oblique photogrammetry. The mathematical accuracy of the DLG is evaluated,and the influence factors of the accuracy are discussed. Through the analysis,the feasibility of the application of UAV oblique photogrammetry technology in 1 ∶ 500 large scale topographic mapping is preliminarily verified.更多还原
