Abstract:

There has been an increasing need for diagnostic methods to detect energy leakage in order to reduce energy consumption of buildings. Currently, an infrared thermography is used as a preliminary investigation tool because it does not cause physical damage during the exploratory investigation. In practice, diagnosis of the building using infrared thermography requires not only building drawings of the building but also the property information of the materials and the information about the joints and junctions of the building components. However, often, accurate building drawings are not available for existing buildings and it makes diagnosis of the building using infrared thermography difficult. This study aims to propose a method to automatically map infrared thermographs acquired during periodic diagnosis of the building to its as-built data without fixing the relative position and direction of the infrared camera and a sensor that is used to acquire the as-built 3D point cloud. The preliminary experimental result shows that the proposed method can automatically map the infrared thermograph to as-built 3D point cloud acquired from different positions and at different times.
