Industrial 3D imaging sensor


3D Sensing plays an guiding role in the logistics robotics. The purpose of 3D sensing 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. Therefore, the quality of 3D sensing determines the performance of the whole system. For this reason, HKCLR has developed this Industrial 3D imaging sensors featuring high speed, high accuracy, high reliability and high level of adaptation to different objects.

The 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

• Human-Robot Collaboration

• Smart Manipulation Robots

• 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 Mainland China. It is expected that the Centre will foster the leading role of the local logistics industry in GBA and Mainland China, meanwhile enhancing its competitive edge in the global arena.
