Modelling and reconstructing the building objects into 3D have been implemented in different domains such as urban planning and 3D city visualization. From the cadastre perspective, the registered 3D property refers to the bounded amount of legal space which is required by physical objects. Therefore, a building model with sufficient geometric representation is the premise of precise registering 3D properties. Along with the rapid development of the 3D data acquisition and reconstruction techniques, now it is possible to model the building objects with detailed geometric information into a 3D form. Mounted on the top of the vehicle, the laser scanners facilitate capturing and recording the spatial information of the urban facilities along the streets at vehicle driving speeds. The spatial information and the geometric structure of the building objects such as the building/storey height, and the overhanging part on the building facades are acquirable from the MLS products and then can be represented on the reconstructed model. In this study, the Mobile Laser Scanning (MLS) data and the processed building facade maps are implemented for the building objects reconstruction. The experimental results show that the applicability of introducing the MLS data and the processed building facade maps for 3D physical building and apartment units modelling in the cadastral registration.
