Device and method to reconstruct face and body in 3D

摘要

The device and method are intended for reconstructing in 3-Dimensions comprehensive representations of the head and torso of subject (S) with a portable stereophotogrammetry device which can operate at, at least, two predefined positions (A3, A4). The device is composed of a camera body (1), a double optics (2) and a measuring distance system (34) enabling the repositioning of subject (S) at position (A3) or (A4). The user can operate a switch (5) to select one of these at least two pre-defined positions. The method is further to process the stereo-pairs of the subject to reconstruct 3-Dimensional surfaces (400), match them (500) and then stitch them (600) in a comprehensive representation of the subject. By selecting a distance corresponding to a field of view of respectively approximately A4 dimension the device and method is enabling reconstructing the face and of approximately A3 dimension is enabling reconstructing the torso of subject (S).

主权项

1. A device for stereophotogrammetry comprising a camera body (1) and a double-optics (2) comprising two sub-optics (2b) and (2c), configured for a simultaneous acquisition of two views according to two different angles, wherein the device is comprising a distance measurement system (34) configured to ensure a positioning of a target subject (S) at one of at least two distinct pre-defined point positions (A3, A4) of the target subject (S) relative to the stereophotogrammetry device, the at least two distinct predefined point positions comprising a closer point position (A4) and a farther point position (A3), the closer point position (A4) being closer to the stereophotogrammetry device than the farther point position (A3).
