Point cloud based viewshed generation in AutoCad Civil 3D

Abstract

W artykule została przedstawiona metoda tworzenia wykresu widoczności na podstawie chmury punktów. Zaprezentowano zarówno znane dotychczas metody wyznaczania wykresów widoczności jak i metodę bazującą na chmurze punktów zaimplementowaną w oprogramowaniu AutoCAD Civil 3D. Omówiono również nowe rozwiązanie problemu przetwarzania dużej chmury punktów za pomocą programu AutoCAD Civil 3D oraz propozycję automatyzacji tego procesu.

We propose a new method for a point cloud based viewshed generation. We start with a brief summary
of existing methods for viewshed generation and then present ours based on point clouds. The method is implemented in AutoCAD Civil 3D. Moreover, we present an idea of how to deal with huge point clouds using AutoCAD Civil 3D and how to automatize this process.

Keywords
