Problem addressed

The purpose of this product is to acquire the 3D point clouds of the objects and environments. Based on the point clouds, individual object segmentation, surface inspection, and semantic meaning understanding will be conducted, so that various robotic tasks can be implemented.

Innovation
  • The binocular camera system with proprietary matching algorithms addresses object occlusion and surface reflectivity challenges in industrial environments while maintaining high-fidelity imaging performance.
  • The self-developed hybrid technology combining fringe structured light and line structured light enables high-accuracy 3D reconstruction of transparent objects.
  • 5-megapixel point cloud output enables higher-precision quality inspection and guidance applications, with repeat measurement accuracy reaching micron-level performance.
Key impact
  • Our self-developed hybrid technology combining fringe structured light and line structured light enables high-accuracy 3D point cloud reconstruction of transparent objects, such as inflatable foams and cosmetic bottles.
  • The compact design achieves wider scanning coverage at the same working distance.
  • The binocular camera system with proprietary matching algorithms addresses object occlusion and surface reflectivity challenges in industrial environments while maintaining high-fidelity imaging performance.
  • The ruggedized and sealed design, validated through long-term stability testing, achieves IP65 protection rating, making it adaptable to diverse industrial inspection and guidance applications in harsh environments.

Hong Kong Centre for Logistics Robotics was established in 2020 by The Chinese University of Hong Kong, with research contributions from the University of California, Berkeley. The Centre focuses on the research and development (R&D) of robotics and artificial intelligence (AI) technologies for “future workplace” as well as innovative solutions to the “pressing problems” in the logistics industry. In particular, HKCLR aims to advance robot intelligence in terms of

• Robust Sensing and Perception

• AI-Powered Robot Manipulation

• Human-Robot Collaboration

• Unmanned Logistics Vehicles

The research team is composed of distinguished professors from the two universities and accomplished Ph.D. degree holders across world-leading universities. The Centre is dedicated to pursuing innovative breakthroughs in ready-for-use robotics and AI technologies via close collaboration with academic and industrial stakeholders throughout Hong Kong, the Greater Bay Area (GBA), and Chinese Mainland. It is expected that the Centre will foster the leading role of the local logistics industry in GBA and Chinese Mainland, meanwhile enhancing its competitive edge in the global arena.
