A Sharp Transformation Method for Point Cloud’s Protrusion Using Morphology Operation

Abstract

In this study, we propose a method to transform projections into a sharp model based on parameters calculated from point cloud model. In the conventional editing process of point cloud models, the models are often converted to curved surface models or polygon models. However, if the point cloud data has noise or scan error, it is difficult to generate correct point connections and surfaces. In the proposed method, the point cloud data is directly processed. Specifically, parameters are calculated for each point using point cloud morphology operations, and the model is sharpened by moving the points using the parameters. The effectiveness of the proposed method is verified through experiments of parameter calculation when the size of the structural elements is changed and sharp transformation.
