3D OBJECT MODEL RECONSTRUCTION BASED ON LASER SCANNING POINT CLOUD DATA (original) (raw)
Three dimensional (3D) reconstruction has been widely applied in urban planning, digital city, and the conservation of cultural/archaeological heritage etc. to re-build 3D object geometry. In the situation where the objects are irregular and have complex-structure, the use of conventional methods is time-consuming and mostly not practicable because of the workload involved and the detail of roofs or footprints cannot be modelled and low accuracy. The paper introduces the method of reconstructing 3D object model based on point clouds acquired by 3D terrestrial laser scanner including data acquisition, data processing, multiple scan registration, 3D modelling and texture mapping. The experiment result shows that, the method can effectively and quickly reconstruct 3D object geometry with many details, especially in 3D city model and cultural/archaeological heritage."
