Error ellipsoid to every TLS point. AN EMPRICAL POINT ERROR MODEL FOR TLS DERIVED POINT CLOUDS
What is it about?
The random error pattern of point clouds has significant effect on the quality of final 3D model. The magnitude and distribution of random errors should be modelled numerically. This work aims at developing such an anisotropic point error model, specifically for the terrestrial laser scanner (TLS) acquired 3D point clouds.
Why is it important?
Even though the Terrestrial Laser Scanning (TLS) technology provides accurate 3D description of a target object or scene, individual points of the 3D point cloud contains random and gross errors. These errors propagate through processing steps such as pre-processing, registration, integration and model generation. This fact evokes the question of how reliable the laser scanning data which is widely used for applications vary from cultural heritage to deformation monitoring.
