“Diagnosing the Concrete Jungle”: Building and Infrastructure Inspection using Smart Movable Platforms
Abstract
Concrete structures such as buildings and infrastructure play an important role in sustaining the well-being of society. However, efficient inspection of this massive concrete jungle, so as to pinpoint defects for proactive maintenance, remains an unsolved challenge. The advent of smart movable platforms (SMPs), e.g., drones and ground robots, provides unprecedented tools to tackle the challenge. In this talk, the speaker will share his ongoing research on SMPs for building and infrastructure inspection. It will start with an overarching framework to integrate SMPs with existing inspection pipeline. Key technologies involved in the framework will be delineated, which include robot positioning and navigation, human-in-the-loop inspection by augmented reality, semantic-aware defect perception, and defect 3D reconstruction and modeling. Effectiveness of the technologies has been validated with first-hand data collected from multiple case studies. The speaker will conclude by giving an outlook to exciting future directions of the study.

Emerging technologies for collaborative fire emergency response
Abstract
Indoor fire emergency is one of the most dangerous incidents that cause casualties and property damage. Various information (e.g., evacuation routes, firefighting system properties, trapped locations) is desired by different emergency participants but rarely available in practice, making the response operations solitary and inefficient. Emerging technologies, such as BIM, hybrid positioning techniques, and multi-user networking environments have huge potential to assist participants in dynamic route planning, indoor location tracking, emergency information provision, and real-time information sharing. In this talk, the speaker will introduce their utilization for fire emergencies and present a system that integrated these technologies to open up new possibilities for response collaboration. A real-life case study and a system evaluation will be shared to clarify the breakthroughs, limitations, and future work.
