Abstract:
A method of measuring a body region of a human body, comprising:arranging in a fixed spatial relationship with the body region a reference object, having a reference zone of a previously known length and an angle-determining device; arranging a camera in a first camera position in a first viewing direction, perpendicular to the reference zone, to view the body region with the reference object; recording a first image; arranging a camera in a second camera position, in a second viewing direction, perpendicular to the reference zone, to view the body region with the reference object; recording a second image; determining first and second reference distances, which correspond to distances of the reference object from the first and second camera positions, from the length of the reference zone and the projected images of the reference zone on the images; determining a contour line exending in three-dimensional space for each image from said reference distances on the oasis of a previously stored reference model; and determining an individual model of the body region from said contour lines and said reference model.
