摘要
近年来倾斜摄影技术不断发展,应用领域及产品类型日益丰富。利用飞行平台搭载倾斜航摄仪,通过采集多角度影像数据,构建高精度的实景三维模型,并以此为基础开展大比例尺地形图测绘,正成为当前研究的热门课题。本文结合烟台市中心城区实际案例,探索研究了基于实景三维模型开展大比例尺地形图测绘的技术流程,通过对成果精度进行评定分析,验证了方法的可行性。
In recent years,oblique photogrammetry continues to develop,and its application fields and product types are more and more abundant.It has become a hot topic to use the oblique aerial camera on the flight platform to collect multi-angle image data,build a high-precision three-dimensional model of the real scene,and carry out large-scale topographic mapping based on it.Based on the actual case of Yantai city center,this paper studies the technical process of large-scale topographic mapping based on the real 3 D model,and verifies the feasibility of the method through the evaluation and analysis of the quality of the results.
