Abstract: A quick release mounting arrangement for a portable gauging sensor utilizes three locating surfaces to establish a positive, repeatable mounting for the releasable sensor at any desired number of locations on a gauging fixture. A landing pad at each mounting location provides a depressed cavity in a first face for receipt of a first locating surface carried by the sensor housing, and the landing pad further provides a grooved surface in a second face for receipt of the second and third locating surfaces carried by the sensor body. At least one of the three locating surfaces is movable under spring tension to provide a quick connect/disconnect feature to the sensor mounting arrangement.

Abstract: A three-dimensional triangulation-type sensor-illumination system adapted for connection to a machine vision computer. The illumination source in the preferred system comprises a unique cross hair light pattern which provides sufficient image data to the computer to enable the computer to make three-dimensional measurements of a wide variety of features, including edges, corners, holes, studs, designated portions of a surface and intersections of surfaces. The illumination source and sensor are both mounted within a single housing in a specific position and orientation relative to one another, thereby permitting the system to be internally calibrated. In addition, the sensor-illuminator unit is preferably mounted in a test fixture so that the light source is substantially normal to the surface of the part to be examined and the sensor is thereby positioned at a perspective angle relative thereto.
