Discovery Corner - 3D Scanning Services


Overview

As part of our effort to support the University’s DEC initiative and to encourage cross-disciplinary collaboration, the Library is now introducing 3D scanning services. The objective is to foster creativity, scholarly research among CityU staff and students. 3D scanner analyses a real-world object or environment to collect data on its shape and possibly its appearance. The data so collected can be used to construct digital three-dimensional models. The Library provides two types of 3D scanners. Explore and try out your new ideas using these scanners!

Scanners available

Handheld Scanner (Structure Scanner) [Seat: 901]

The Handheld 3D Scanner is the Structure Sensor 3D Scanner which can be checked out at the Information Space Counter. This Scanner uses an infrared laser projector to cast a specific pixel pattern on the scene in front of the sensor. The Scanner has a great potential for 3D modelling and discovery. Please click here for more information.

Technical specifications:

Brand Structure Sensor
Minimum Distance 40 cm
Maximum Distance 350+ cm
Precision 1% of measured distance (typical)
Resolution 640 x 480(VGA) or 320 x 240(QVGA)
Frame-rate 30 / 60 frames per second
Illumination Infrared structured light projector, Uniform infrared LEDs
Field of View Horizontal: 58 degrees, Vertical: 45 degrees

Desktop Scanner [Seat: 902]

The Scanner provides scanning processes by using HD CMOS sensor with 2 lasers. The scanning process may last for over 2 hours depending on the resolution required and the object size. Please click here for more information.

Technical specifications:

Object size Height: 25 cm (9.8 in)
Diameter: 18 cm (7.0 in)
Weight: 3.0kg (6.6 lbs)
Scanning accuracy Capture details as small as 0.43mm
Capture size within ±0.25mm
Scanning time The scanning is a time consuming process, which may take up to several hours
depending on the number of scans taken to build the finished model.

Locations of the scanners

The 3D Scanners are available at the Information Space Counter.

Terms of Services

  • 3D Scanners are free for use by all CityU students, staff of programmes leading to CityU awards including associate degree, bachelor's degree and postgraduate degree.
  • The Handheld Scanner must be checked out and returned to the IS counter during service hours. The Desktop Scanner is to be used at the back of the counter.
  • The Scanners may be booked for up to a maximum of 4 hours per day.
  • To ensure fair access to all eligible users, the Scanners are booked on a first-come, first-served basis.
  • The check-out operation also includes the use of a powerful workstation for the scanning service.
  • 3D Scanners are used only for lawful purposes. No one will be permitted to use the Library’s 3D scanner to create digital objects that are against the law, obscene, in violation of another’s intellectual property rights.
  • All scanner requests are subject to approval based on scheduling and availability. The Library reserves the right to refuse any 3D scanning requests for any reason.
  • The scanning time depends on the number of scans and the object size and it may be time consuming. The Library cannot guarantee a specific scanning time, however, the user can consult the Library colleague at Information Space for an estimated time.
  • Only designated Library staff will have hands-on access to the 3D scanners.
