Abstract
An apparatus for the measurement and numerical description of three-dimennal objects, such as human heads. The apparatus comprises a hollow hemisphere having a plurality of probes which can be moved toward or away from a three-dimensional object held in place within the hollow hemisphere. The probes are movable in sleeves which pass through the wall of the hemisphere, enabling the measurement of distances between the hemisphere and the three-dimensional object at various points on the outer surface thereof.
Claims3
An apparatus for the measurement and numerical description of a three-dimensional object which comprises, a hollow, transparent hemisphere, said hemisphere being sufficiently large to accommodate said three-dimensional object therein with space remaining between the outer surface of said three-dimensional object and the inner surface of said hemisphere, a plurality of cylindrically shaped solid rod probes, each of said probes fitting snugly in a sleeve extending through and lockably and unlockably attached to the wall of said hemisphere so that said probe is adapted to be moved inwardly and outwardly of said hemisphere, and means for adjustably supporting and clamping said hemisphere in a plurality of selected positions in relation to said three-dimensional object, whereby said probes may be moved inwardly of said hemisphere until they contact the outer surface of said three-dimensional object at a plurality of points and the distances from the inner surface of said hemisphere to the outer surface of said three-dimensional object at said plurality of points measured and converted into a numerical description of said three-dimensional object.
