Aprašomas erdvinio paviršiaus taškų rinkinio apdorojimas, t. y. paviršiaus taškų rinkinio filtravimas ir suglodinimas. Taip pat pateikiami eksperimentinių tyrimų rezultatai, metodų privalumai ir trūkumai bei galimos metodų tobulinimo kryptys.
Point cloud processing (filtering and smoothing) was described in this article. In most cases point clouds obtained from 3D laser scanners or range measuring devices contains noisy samples. These noisy samples can be removed by deleting points which are most distant from their neighbours by evaluating some criteria. Other way to reduce amount of noise is point cloud smoothing. Smoothing operation is performed by projecting point to least square projection plane which approximates points neighbourhood. Results of point cloud filtering and smoothing are presented in this article.
