A 3D reconstruction method for construction sites


We propose a new 3D reconstruction solution for construction sites. Using our self-developed handheld 3D scanner, we can easily and efficiently complete 3D scanning and modeling of the environment, and produce real-time drawings without preliminary site layout or secondary splicing.

Problem addressed

By holding a 1.5kg 3D scanner and walking around the site, you can immediately get the colorful spatial structure data, which can be used for high-precision remote monitoring, progress management, quality management, and BIM drawing comparison.

  • High-precision scanning on the move
  • Accuracy can be adapted to various needs of construction sites, including progress management, quality management and BIM drawing comparison, etc.
  • Colorful three-dot cloud information can be output directly on the phone
Key impact
  • Scanning tasks can be done handheld
  • Highly efficient image output and real-time display of scan results
  • Millimeter accuracy, Meets most site requirements
  • Can be placed on a variety of chassis to complete mobile scanning tasks
  • Technology Start up Support Scheme for Universities(TSSSU)
  • Ideation Plan
  • Construction sites that require 3D data retention and progress management
  • Provides modular 3D information that can be used for assembled construction plants
  • Provide three-dimensional information on rough housing for the home renovation industry

Hong Kong Center for Construction Robotics (HKCRC), a scientific research and entrepreneurship platform, was established in 2020 as a joint collaborative effort among the Hong Kong University of Science and Technology (HKUST), University of California, Berkeley, and Tsinghua University. It belongs to the InnoHK project of the Hong Kong government. Led by Professor Li Zexiang, HKCRC gathered the world's top professors, scholars, and industrial resources to build an intelligent business incubator for the construction industry. HKCRC is committed to bringing advanced technologies such as robotics, automation, and AI into the construction industry and transformative changes to the construction industry.
