This paper focuses on earthquake/tsunami damage investigation over urban areas by exploring the multitemporal spaceborne ALOS/PALSAR PolSAR data. The polarimetric scattering mechanism changes before- and after-tsunami, at the city block scale, have been examined using model-based decomposition and PO angle techniques. These analyzes are used to establish the relationships between the polarimetric...
Baroque and Post-modernism architecture both are most dynamistic period in history. Innovative spirit is the essence behind the architecture phenomena. This paper discusses the two periods of architecture on the society background, and analyzes of their expresses on architecture design, researches the time and innovative spirit, in order to find the inner generating pattern of form in the two periods...
This paper discusses an energy-efficiency supervision and diagnostic system (ESDS) to address the problem that the air-condition system do not perform as well as anticipated. The ESDS consists of a set of sensors, data acquisition system, data analysis and diagnostics system including a web-based remote access system that can be used to identify problems in operations. The operation state of a typical...
Registration of point clouds from terrestrial laser scanners plays the key role in feature extraction, 3D object modeling and 3D scene classification. An automated registration algorithm of pair-wise point clouds is presented, which is based on multi-resolution data created from raw point clouds, using geometric properties and point to point improved adjustment method, iteratively calculates six transformation...
Segmentation of unorganized point cloud is the key procedure of 3D model construction. And also the problem of management of massive point clouds can be manipulated with segmentation techniques. Global segmentation parameters and metrics are the most essential and difficulty parts of segmentation algorithm, especially in urban region. An optimization solution for segmentation of unorganized point...
