Název v původním jazyce

Adaptive lidar grid filtering and utilization in the automated photorealistic surface modelling

Popis výsledku v původním jazyce

This article proposes a suitable method for processing irregular data from aerial laser scans (technology LIDAR). The article focuses on comparing interpolated grids against the original scanned values. Interpolated grids are created in the previous research on the basis of the global and local interpolation methods and slope analysis of the terrain. The terrain is divided into three main groups by elevation changes. Each group has a different resolution. Interpolation is spatial based. This segmented set of grids is used to create a polygonal 3D model, which is inherited from laser attributes. A prerequisite for this creation is grid quality analysis. This operation is made by split sample validation that is enhanced by backward error propagation. This error creates continuous raster correction maps for each grid and it helps to fit the interpolated regular grid to irregular structure. This process minimizes uncertainty in comparing the known values. Remaining differences are computed
