三维激光扫描技术在地质测绘中的应用研究

Research on the Application of 3D Laser Scanning Technology in Geological Surveying and Mapping

传统的地质测绘方式不仅周期长、用工量大、危险性高、测量误差大精度底、成本高。而三维激光扫描技术的出现极大改善了传统测绘技术的缺点,有效降低了外业人员工作量,提高了测绘人员安全,大幅提升了地质测绘的信息化及自动化程度。该技术可充分扫描物体三维点数据以及一些高精高分数字地形模型。本文结合某矿山测区案例详细分析了三维激光扫描技术在矿山地质测绘中的应用,通过对比传统测量方式,在测绘时间、测绘精度、人员等方面有不错的经济效益。

Traditional geological surveying and mapping methods have long cycles,high labor costs,high risks,large measurement errors,low accuracy,and high costs.The emergence of 3D laser scanning technology has greatly improved the shortcomings of traditional surveying and mapping technology,effectively reduced the workload of field workers,improved the safety of surveying and mapping personnel,and greatly improved the informatization and automation level of geological surveying and mapping.This technology can fully scan 3D point data of objects and some high-precision and high-resolution digital terrain models.This article provides a detailed analysis of the application of 3D laser scanning technology in geological surveying and mapping of a certain mining area.By comparing traditional surveying methods,it has good economic benefits in terms of surveying time,surveying accuracy,personnel,and other aspects.
