A method for automatic generation of road surface type using a mobile mapping system

摘要

More particularly, the present invention relates to a vehicle-based mobile mapping system (MMS) comprising a high-performance GPS / INS, DMI, and a device for acquiring image information such as a laser scanner and a digital camera. The present invention relates to a road surface type automatic acquisition method using a mobile mapping system for automatically acquiring a surface shape of a road using MMS data acquired from a mobile mapping system. A method of automatically acquiring a road surface using a mobile mapping system according to the present invention includes a first step of generating three-dimensional LAS data using MMS data acquired in a mobile mapping system, a step of extracting a three- A third step of setting a tolerance range and a correlation threshold for extracting a road surface point at the three-dimensional point, and a third step of applying the tolerance range and each threshold value of the correlation to the three- A fourth step of filtering road surface points, and a fifth step of generating a road surface shape using the filtered road surface points.
