Subeject Orientation

Focusing on the large and complicated architectural structures, this research area mainly studieshigh-speed video measurement, collaborative multi-sensor 3D construction surveying with high precision, virtual positioning and assisted installation of building structures by combining forward and backward models, and theory and methods for monitoring health condition and deformation of building structuresby terrestrial SAR and tomography SAR. The research has developed a complete theory and technology system for precision surveying of architectural structures from safety testing of model vibration table in design stagethrough assisted installation and quality control in construction stage to health and safety inspection during operation and maintenance. Research results have been successfully applied to the construction of many national and local landmarks such as national stadium, national grand theater and China Zun Tower. The research team hasreceived the second-place prize of the State Science and Technology Progress Award for their achievements.

Fine management of urban operations

Focusing on the fine management of urban operations by integrating spatial information technologies,internet of things and other information technology, this research areamainly investigates key technologies for smart monitoring of urban operation internet of things, traffic monitoring and simulation, urban supply chain coordination mechanisms, simulation and emergency management of unexpected events, and GIS software quality assessment, to solve problems of location-based services, smart sensing, simulation and command and decision-making in urban operation, emergency management and command decision- makings. The research team has produced more than 10 authorized patents, developed 1 national standard and over 10application systems for automatic GIS software testing and fine urban operationmanagement of, and won 1 first- place awards and 4 second-place awards at the provincial orministeriallevel.

Digital Architectural Heritage

This research area mainly focuses on digital architectural heritage, especially precise modeling and health condition monitoring of architectural heritage by integrating remotely- sensed data and ground-based measurements from multi- sensors, virtual restoration of cultural relics, and theory, technologies and methods fornondestructive identification of cultural relics using multi-spectral or higher-spectral imagery. The team, as one of earlier groups that conducted digital architectural heritage protection, has developed a set of technologiesfor precision surveying and 3D reconstruction of ancient architectureswith largewooden structures, health detection of stone relics and virtual restoration. Theteam has also completedthe digital protection of a series of famous ancient architecturesincludingForbidden City and Yungang Grottoes, and built thebiggest ancient architecture database in China. Researchers of the team have won the first place of the national teaching award in 2014 and4 provincial science and technology achievement awards.
