There are more than 30,000 old buildings and various types of civil and environmental engineering infrastructure in Hong Kong that require regular checking and maintenance, and some even require urgent repairs. The current practice of manual visual inspection is time-consuming, labor-intensive, and potentially inaccurate. Further aggravated by manpower shortages, these constraints could cause ineffective maintenance and lead to public safety issues, hindering the city’s daily operation. In addition, urban forestry in Hong Kong also faces a similar challenge. To address these pressing needs and transform Hong Kong into a truly smart and resilient city, this project aims to develop an integrated solution empowered by human-machine synergy: the Human-Robot-AI Symbiotic Mobile Mapping Solution for Fast and Regular Examination of Rapidly Evolving Civil Engineering Infrastructures of Hong Kong on a city scale.
