无人机倾斜摄影测量技术在大比例尺测图中的应用及精度评价

Application and Accuracy Evaluation of Unmanned Aerial Vehicle Oblique Photogrammetry Technology on Large Scale Mapping

传统的大比例尺测图主要采用外业实测的方法,人工成本高、效率低。无人机倾斜摄影测量技术凭借低成本、高效率、灵活可靠、高精度等优点,在国土规划、农林水利、地籍测量等领域得到广泛应用。本文结合项目实际,通过无人机倾斜摄影测量技术在大比例尺测图中的应用研究,建立了完整的技术流程,验证了技术的可行性和成果精度的可靠性。

Traditional large-scale mapping mainly adopts field measurement method,which has high labor cost and low efficiency.Unmanned aerial vehicle oblique photogrammetry technology has the advantages of low cost,high efficiency,flexibility,reliability,and high accuracy,and has been widely used in land planning,agriculture,forestry,water conservancy,cadastral survey,and other fields.Based on the actual project,this paper conducts the application research of UAV oblique photogrammetry technology in large-scale mapping,establishes a complete technical process,and verifies the feasibility of the technology and the reliability of result accuracy.
