摘要:

提出了基于DEM的单张倾斜航片快速量测方法。该方法根据影像与建筑物之间的位置、姿态等特征,推导出单张影像量测数学模型及计算公式,并选择试验区域对本文算法的精度进行验证。试验结果表明,研究区内平面点位误差小于0.13 m,建构筑物每层的垂直误差约为0.11 m,能够满足城市规划与管理的应用需求,可为城市三维数据获取提供经验和借鉴。

Abstract:

This paper improved a fast measurement method of single oblique aerial photograph supported by DEM. According to the difference of position and attitude between images and buildings, the measurement method of single image is studied, and the calculation formulas are deduced. Then verify the accuracy of the algorithm, and analyze the specific impact factors by selecting test area. The experimental result shows that the horizontal and vertical accuracy of the study area is satisfying, which can meet the application needs of fields such as urban planning and management, and will provide experience and reference for urban 3D data acquisition.

Key words: oblique photography, single image measurement, DEM, height measurement
