3D Handscanner: to obtain a 3D surface model of the hands

Themes: Life Science & Health


A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

3D Scans of the hand are time- and labour-intensive, but necessary to produce personalized products like surgical instruments, orthoses and prosthetics. This research developed a dedicated and affordable 3D Handscanner.


The user-friendly device simultaneously takes multiple pictures of the hand from different angles and combines these almost instantly into a highly detailed and accurate 3D surface scan of the hand using photogrammetry.


The prototype is further improved from a system level, enhancing user-friendliness for user and patient. Possible other applications, for instance in customised sportswear, are explored.
