When we cannot use an original blueprint due to undocumented interior renovation or loss, we have measured and drawn structures manually. However, it is too time-consuming and inconvenient. Moreover, many objects placed in a room often occlude corners and edges of the room, which makes 3D indoor structure modeling more difficult. In this paper, we propose a new method for 3D indoor structure reconstruction which results in a simple CAD-structure with automatic process. For data collection of the indoor environment, we used a 3D laser sensor. For modeling structures, we classify the obtained 3D point clouds as structures and objects. Plane extraction among structure-PCD is followed since an extracted plane is intuitively part of a wall considering that indoor space is enclosed with walls. From the extracted planes, we seek points where three planes intersect since some intersection points are occluded by objects placed at the corner. Then several valid intersection points are determined as real structure points by the Plane-Patch test, eliminating other points that do not really exist. After that, we connect the valid structurepoints belonging to the ceiling, which creates a contour. With this, we can generate a floor plan of an indoor room. Considering the distance between the ceiling and the floor, finally, we reconstruct the 3D indoor structure as a simple CAD model. We applied this method to an indoor environment which consists of four rooms and obtained the results successfully.
