基于倾斜摄影测量技术的矿山地形实景三维建模研究

Research on 3D modeling of mine terrain based on oblique photogrammetry technology

由于原有三维建模方法建立了矿山地形实景三维模型分辨率较低,为此提出基于倾斜摄影测量技术的矿山地形实景三维建模研究。通过对测量仪器设备选型以及技术参数设定,利用倾斜摄影测量技术对矿山地形实景三维数据进行采集;对采集到的数据进行归一化处理,为三维模型建立提供数据支持;采用GeoIPAS V3.2软件对数据进行网格化生成,以此完成矿山地形实景三维建模。经实验证明,此次提出的建模方法建立的三维模型分辨率高于传统方法。

Due to the low resolution of the original three-dimensional modeling method to establish the mine terrain real 3D model,a study of mine terrain real 3D modeling based on tilt photogrammetry technology is proposed.Through the selection of measuring instruments and equipment and the setting of technical parameters,the tilt photogrammetry technology is used to collect the real 3D data of mine terrain;the collected data are normalized to provide data support for the establishment of 3D model;the GeoIPAS v3.2 software is used to generate the data grid,so as to complete the 3D modeling of mine terrain.The experimental results show that the resolution of the proposed method is higher than that of the traditional method.
