4D imaging system for human movement

Work is supported the project PBS3/B9/43/2015 funded by the National Centre for Research and Development, PBS3/B9/43/2015

The project objective is to develop a novel 4D|BODY system for three-dimensional imaging of whole surface of human body (4D), with acquisition frequency up to 120Hz. The system will perform measurements of geometry of human body surface within a 2m x 2m x 2m cube with approximated spatial resolution of 1mm and accuracy not lower than ±0,4mm using a single frame structured light illumination method. A single measurement result is roughly evaluated to contain 10 million (x, y, z) points describing temporary surface shape of the body. Numerical algorithms will be developed, which will allow to fit the skeleton and track its movement, as well as identify and track selected anatomical structures (scapula, patella etc.) and determine temporary sections and volumes along with their temporal characteristics. The system will be tested in two contexts: medical and multimedia.

As part of the 4D|BODY project, a measurement system was created that allows the recording of the human body in motion. The system provides omnidirectional, complete body measurement with a frequency of up to 120 Hz. The output data from the system is in the form of point clouds that can be processed into commonly used formats, including STL. The attached image shows one frame from the measurement (the triangle mesh was generated for a maximum triangle side of 6 mm).
