在过去的5年里，地面激光扫描（TLS）技术无论是在仪器方面还是在数据处理和可视化软件方面都取得了很大的进步。由于操作范围小，最初的应用只涉及建筑或一般的近距离领域，而现在处理大型场景也是可能的。新的“远程”TLS非常适合应用于地质和冰川学调查和监测，这对意大利（不仅是）研究和社会团体来说是一个非常有趣的问题，因为它的大部分土地都是山地特征。本文提出了利用TLS技术进行滑坡测量的一些指导原则；涉及三维视图注册、测量规划、数据处理、信息提取等问题。此外，介绍了由米兰理工大学和布雷西亚大学组成的研究小组在该领域的两个应用。地质应用涉及对科莫湖附近Caslino d 'Erba村的一部分斜坡的调查，以及著名的boticino（布雷西亚）大理石采石场。
In the last 5 years terrestrial laser scanning (TLS) technology has shown very large improvements, either in the instrumental aspects and in softwares for data processing and visualization. While first applications concerned only the architectural or in general the close-range field due to the small operating range, nowadays dealing with large scenarios is possible as well. New “long-range” TLS are really suitable to be applied in geological and glaciological surveying and monitoring, representing a very interesting issue for the Italian (and not only) research and social community, due to the mountain character of a large portion of its land. In the paper some guidelines for executing a survey of a landslide by means of TLS techniques are addressed; problems such as 3Dview registration, survey planning, data processing and information extraction are concerned. Furthermore, two application in this field carried out by a research group made up of Politecnico di Milano and the University of Brescia are presented. Geological application concerns the survey of a slope threatening a part of the village of Caslino d’Erba, near the Lake of Como, and the wellknow marble quarry of Botticino (Brescia).
