Abstract
Abstract. The recent push for natural user interfaces (NUI) in the entertainment and gaming industry has ushered in a new era of low cost three-dimensional sensors. While the basic idea of using a three-dimensional sensor for human gesture recognition dates some years back it is not until recently that such sensors became available on the mass market. The current market leader is PrimeSense who provide their technology for the Microsoft Xbox Kinect. Since these sensors are developed to detect and observe human users they should be ideally suited to measure the human body. We describe the technology of a line of NUI sensors and assess their performance in terms of repeatability and accuracy. We demonstrate the implementation of a prototype scanner integrating several NUI sensors to achieve full body coverage. We present the results of the obtained surface model of a human body.
Highlights
Human body measurement has an established history of measurement systems and applications over the past 30 years
Within this paper we will demonstrate the application of a natural user interfaces (NUI) sensor to human body measurement
As discussed above the NUI sensor used in this prototype, as generally all the sensors based on the PS1080, contains a substantial amount of noise
Summary
Human body measurement has an established history of measurement systems and applications over the past 30 years. Measurement systems are typically purpose-built optical scanners. The optical measurement principles employed by existing commercial solutions are laser line triangulation, active triangulation using white light pattern projection and monocular vision. An overview of systems and principles is given by (D’Apuzzo, 2005). Literature reports prices of commercial scanners ranging from $35,000 up to $500,000, which has prevented the widespread use of these systems so far. Different sensor systems from monocular cameras to time-offlight cameras have been suggested to capture a user’s gestures. Within this paper we will demonstrate the application of a NUI sensor to human body measurement. We report on our prototype implementation of an 8 sensor set-up and show first data sets captured with the system
