Abstract. Building change detection is essential for monitoring urbanization, disaster assessment, urban planning and frequently updating the maps. 3D structure information from airborne light ranging (LiDAR) very effective detecting changes. But point cloud LiDAR(ALS) holds an enormous amount of unordered irregularly sparse information. Handling such data tricky consumes large memory processin...

Fault Detection and Diagnosis in Building HVAC Systems

This paper is concerned with the integration of photogrammetric and LiDAR data for accurate generation of complex Digital Building Models (DBM). Some research has been conducted utilizing either high overlap/sidelap photogrammetric data or high point density LiDAR data in order to specifically cater to DBM generation. In contrast, the proposed methodology is designed to utilize imagery and LiDA...

Range measuring sensors can play an extremely important role in robot navigation. All range measuring devices rely on a ‘detection criterion’ made in the presence of noise, to determine when the transmitted signal is considered detected and hence a range reading is obtained. In commonly used sensors, such as laser range finders and polaroid sonars, the criterion under which successful detection...

Line matching plays an important role in building reconstruction, because majority buildings are composed of line segments along boundaries. Considering the complexity in image processing, line matching is a challenging work. The building reconstruction with line matching algorithm is performed using high overlapping aerial images in this study. The strategy is to determine the building boundar...

The paper aims to extract the dynamic properties of existing structures without utilizing the analytical models. The ambient vibration testing could be used on any type of frame such as concrete, steel and masonry to investigate the structural vulnerability. The method could be the first stage and necessarily for the retrofit process. To achieve this aim, the ambient vibration testing can...
