A typical task in the operation of the road network is the development of traffic management projects and the creation of technical passports for motorways. To solve them, it is necessary to collect accurate spatial data. As a rule, the most effective way to obtain such information is aerial photography. However, there is an alternative approach - mobile laser scanning. This method can be used in conjunction with aerial photography, or independently, if aerial photography is not possible.<\/p>\n
Mobile laser scanning (MLS) is performed on a vehicle with a laser scanner and satellite geodetic equipment installed. Thus, the resulting cloud of laser reflection points has a precise geographic reference. Examples of MLS and aerial photography results are shown in the illustration below. On the left is a fragment of an orthophotoplan, on the right is the same area in the form of a dense point cloud.<\/p> <\/div>\n<\/div>\n <\/div>\n
