| 4402608 | Room scanning system using multiple camera and projector sensors An arrangement for obtaining three-dimensional position data on surfaces defining a room, and objects enclosed by that room. The room is scanned with a master and slave sensors to determine the three-dimensional profiles of surfaces that are visible to th... | 09/06/1983 |
| 4396945 | Method of sensing the position and orientation of elements in space The invention discloses a method of determining the position and orientation of an element (such as a platform) in space by determining the intersection of a line with a plane (or with another line). Three different implementations are disclosed.... | 08/02/1983 |
| 4285754 | Method and apparatus for producing planar elements in the construction of surfaces and bodies An arrangement for fabricating planar elements which may be stacked for producing predetermined surfaces and bodies. The planar elements have cross-sections corresponding to respective cross-sections of the surface to be constructed. The planar elements a... | 08/25/1981 |
| 4269513 | Arrangement for sensing the surface of an object independent of the reflectance characteristics of the surface A plurality of projectors are positioned in spaced relationship about an object with a surface to be geometrically analyzed. The projectors have cooperating masks which project onto the object illuminated patterns that subdivide the object into predetermi... | 05/26/1981 |
| 4249827 | Arrangement for color coding of surfaces An arrangement in which different surfaces of an object have applied to them transparent layers of different colors. Each layer will transmit one or more colors, while inhibiting the transmission of one or more other colors. By applying different color la... | 02/10/1981 |
| 4238147 | Recording images of a three-dimensional surface by focusing on a plane of light irradiating the surface An arrangement in which a three-dimensional surface is copied by recording images of planar sections of the surface. The surface is subdivided into the sections, and the sections are illuminated in sequence by a projector which directs a plane of light ag... | 12/09/1980 |
| 4225228 | Surface coating for optical inspection An arrangement for coating a surface preparatory to optical inspection. The surface to be inspected for geometrical, physical or chemical characteristics, is cooled to a temperature below freezing. The surface is then sprayed with water and a layer of fro... | 09/30/1980 |
| 4202612 | Arrangement for sensing the geometric characteristics of an object A plurality of projectors are positioned in spaced relationship about an object with a surface to be geometrically analyzed.
