| description | This paper presents a new approach to recognize individual façade objects and to reconstruct such objects in 3D using MLS point
clouds. Core of the approach is a primitive shape based algorithm, which introduces building primitives, to identify the façade
objects separately from other irrelevant objects and then to model the correct topology. The primitive shape is identified against
defined different primitive shapes by using the Douglas-Peucker algorithm. The advantage of this process is that it offers an ability
not only to model correct geometric shapes but also to remove occlusion effects from the final model. To evaluate the validity of the
proposed approach, experiments have been conducted using two types of street scene point clouds captured by Optech Lynx Mobile
Mapper System and Z+F laser scanner. Results of the experiments show that the completeness, correctness, and quality of the
reconstructed building façade objects are well over 90 %, proving the proposed method is a promising solution for modelling 3D
façade objects with different geometric shapes. |
