A method of geometrical analysis of an object comprising: arranging the object on a support (101a, 101b, 101c) formed of a support surface for receiving the object and two upward-directed surfaces (101a, 101b), inclined with respect to the vertical direction and joining the support surface via curved areas (101d, 101e), the two-upward-directed surfaces (101a, 101b) bordering the support surface on two adjacent sides of the support surface, wherein the support is transparent; placing the object in front of retroreflective surfaces (102a, 102b, 102c) arranged substantially parallel to the surfaces of the support and to the upward-directed surfaces (101a, 101b); arranging a first image capture device with combined light source in front of the object, such that one of the retroreflective surfaces is arranged behind the object in line with the first image capture device and its combined light source to light the object from behind, by reflection, with respect to the first image capture device, such that the object as captured by the first image capture device is silhouetted, and wherein the first image capture device is arranged such that the said one retroreflective surface is substantially perpendicular to the image capture direction of the first image capture device; arranging the first image capture device, a second image capture device with combined light source and a third image capture device with combined light source along three non-coplanar directions and wherein each of the three retroreflective surfaces (102a, 102b, 102c) are substantially perpendicular to the image capture direction of one of the first, second or third image capture devices (131a, 131b, 131c); taking at least one photograph of the silhouetted object by the first, second and third image capture devices (131a, 131b, 131c), to obtain images with an outline of the object; and obtaining geometrical parameters of the object based on the outline of the silhouetted object. arranging the object on a support (101a, 101b, 101c) formed of a support surface for receiving the object and two upward-directed surfaces (101a, 101b), inclined with respect to the vertical direction and joining the support surface via curved areas (101d, 101e), the two-upward-directed surfaces (101a, 101b) bordering the support surface on two adjacent sides of the support surface, wherein the support is transparent; placing the object in front of retroreflective surfaces (102a, 102b, 102c) arranged substantially parallel to the surfaces of the support and to the upward-directed surfaces (101a, 101b); arranging a first image capture device with combined light source in front of the object, such that one of the retroreflective surfaces is arranged behind the object in line with the first image capture device and its combined light source to light the object from behind, by reflection, with respect to the first image capture device, such that the object as captured by the first image capture device is silhouetted, and wherein the first image capture device is arranged such that the said one retroreflective surface is substantially perpendicular to the image capture direction of the first image capture device; arranging the first image capture device, a second image capture device with combined light source and a third image capture device with combined light source along three non-coplanar directions and wherein each of the three retroreflective surfaces (102a, 102b, 102c) are substantially perpendicular to the image capture direction of one of the first, second or third image capture devices (131a, 131b, 131c); taking at least one photograph of the silhouetted object by the first, second and third image capture devices (131a, 131b, 131c), to obtain images with an outline of the object; and obtaining geometrical parameters of the object based on the outline of the silhouetted object.
