A typical task in the operation of road networks is the development of traffic organization projects, designing and updating road technical documentation. To solve these tasks, accurate spatial data is required. Typically, aerial photography is considered the most effective way to obtain such information. However, there is an alternative approach - mobile LiDAR scanning. This method can be used in conjunction with aerial photography or independently if aerial photography is not possible.<\/p>\n
Mobile LiDAR scanning (MLS) is performed using a vehicle equipped with a LiDAR scanner and satellite survey equipment. Thus, the resulting point cloud of laser reflections has precise geographic referencing. Examples of MLS and aerial photography results are shown in the illustrations below. On the left is a fragment of an orthomosaic, and on the right is the same area displayed as a dense point cloud.<\/p> <\/div>\n<\/div>\n <\/div>\n
