摘要
随着无人机系统及实景三维建模软件的快速发展,实景三维建模变得快捷和简单,具有高精度位置信息的实景三维模型为矿山大比例尺地形要素采集提供了基础数据。介绍了基于无人机倾斜摄影实景三维模型进行矿山地形要素采集的工艺流程,并通过应用实例进行了矿山实景三维建模及1∶500地形要素采集。通过实地精度检查,实景三维模型具有较高的地理位置精度,采集的地形要素经验证能够满足1∶500矿山地形图测绘的精度要求。
With the rapid development of unmanned aerial vehicle(UAV)system and real-world three-dimensional modeling software,real-world three-dimensional modeling becomes fast and simple.The three-dimensional model with high precision location information provides basic data for large-scale topographic elements acquisition in mines.This paper introduces the technological process of mine topographic elements acquisition based on the three-dimensional model of UAV tilt photography,and carries out mine topographic elements acquisition and three-dimensional modeling through an application example.Through field accuracy inspection,the three-dimensional model of mine topographic elements acquisition has high geographic location accuracy.The experience of the collected topographic elements proves that it can meet the accuracy of 1:500 mine topographic map mapping.
