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).
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 positioning system (34) configured to signal when a target subject (S) is reaching a pre-defined distance position to the camera (1) corresponding to one of at least two distinct pre-defined distance positions (A3, A4) of the target subject (S) relative to the camera body (1) of the stereophotogrammetry device, the at least two distinct predefined distance positions comprising a closer distance position (A4) and a farther distance position (A3), the closer distance position (A4) being closer to the camera body (1) of the stereophotogrammetry device than the farther distance position (A3) to the camera body (1) of the stereophotogrammetry device.
