Automatic Construction of 3D Basic-Semantic Models of Inhabited Interiors Using Laser Scanners and RFID Sensors

Abstract

This paper is focused on the automatic construction of 3D basic-semantic models of inhabited interiors using laser scanners with the help of RFID technologies. This is an innovative approach, in whose field scarce publications exist. The general strategy consists of carrying out a selective and sequential segmentation from the cloud of points by means of different algorithms which depend on the information that the RFID tags provide. The identification of basic elements of the scene, such as walls, floor, ceiling, windows, doors, tables, chairs and cabinets, and the positioning of their corresponding models can then be calculated. The fusion of both technologies thus allows a simplified 3D semantic indoor model to be obtained. This method has been tested in real scenes under difficult clutter and occlusion conditions, and has yielded promising results.

Building Information Modeling (BIM) for existing buildings — Literature review and future needs

“…Functional issues in the areas of maintenance [7,11,12,14,20,45,[49][50][51][52][53][54][55][56] and deconstruction [2,24] are addressed separately and mainly for new buildings (see Table 3). Also, informational [26,27,50,[57][58][59][60], technical [19,31,40,43,45,[61][62][63][64][65][66] and organizational/legal [21,67] issues of BIM use are often examined separately. Publications on informational issues mainly consider new buildings' requirements, whereas the publications on technical issues focus either on capturing construction data or geometries of existing buildings for processing into digital building models [19,31,62].…”

Evolution of RFID Applications in Construction: A Literature Review

“…Vision systems can be composed by cameras, which provide bidimensional images in which several object parameters are extracted [71] or laser scanners, which give 3D information of the scene [70,72]. An example of a current development in which RFID is introduced in construction is shown in this subsection.…”

Target-Free Automatic Registration of Point Clouds

“…Once the corner point is obtained for each point cloud, the translation vector is determined as the difference between the positions of the two corner points. The calculations involved in this step are shown in detail in Equation (10). …”

“…This method is widely used in outdoor studies, but suffers from a lack of accuracy in the registration process because of the low accuracy of GPS. For indoor registration, an automatic construction of 3D basicsemantic models of inhabited interiors was developed using laser scanners with RFID [10]. This method is applicable only for indoor spaces, and the laser scanner is required to be set up in close proximity to the objects in order to recognize the RFID tags.…”
