The study of 3D modelling accuracy using terrestrial laser scanning data of Geomax Zoom 300

One of the tasks solved by terrestrial laser scanning data is three-dimensional modeling of territories. Due to the high density of the resulting point cloud, it is possible to create three-dimensional models of objects with a high level of detail. To date, a large number of models of laser scanners have been released, the technical characteristics of which can be significantly distinguished. To understand the possible accuracy of constructing three-dimensional modes based on the data of a certain laser scanner model and where the scan positions should be placed, a number of studies have to be preliminary performed. The accuracy analysis of the laser scanning data obtained using Geomax Zoom 300 and the results of three-dimensional modeling based on control measurements is carried out. Recommendations have been proposed for the use of this laser scanner model to construct 3D models of maximum possible accuracy and detail.
