三维激光扫描技术是一项新兴的测绘技术,主要利用激光测距原理来获取目标实物的三维坐标数据,然后通过一些后处理方法建立高精度的三维模型。目前,该技术在工程地质和岩土工程领域有一定的应用尝试与研究,但总体来讲还为数不多。该文结合具体的高陡岩质边坡工程的地质调查工作实例,阐述三维激光扫描技术的基本原理,并详细地介绍数据处理方法及其成果提取应用——主要包括图切工程地质剖面获取和危岩体调查等。文章的最后,就该技术在高陡岩质边坡地质调查工作中的应用的优点进行归纳总结。
Three-dimensional laser scanning technology is an emerging mapping technology, mainly using laser ranging principle to obtain the target three-dimensional coordinate data, and then through some post-processing methods to establish high-precision three-dimensional model. At present, the technology in the field of engineering geology and geotechnical engineering have some application and research, but in general is still small. In this paper, the basic principle of three-dimensional laser scanning technology is elaborated with the example of geological survey of high-steep rock slope engineering, and the data processing method and its application are introduced in detail. Dangerous rock body investigation. At the end of this article, the advantages and disadvantages of the application of this technology in geological survey of high and steep rock slopes are summarized.
