摘要： A non-contact sensing system is provided for acquiring three-dimensional contour information of an object. The system is comprised of: a light source subsystem operable to scan a point of light in an area of illumination; a first imaging device having a field of view arranged to intersect with the illumination area and operable to capture image data; and a second imaging device having a field of view arranged to intersect with the illumination area and operable to capture image data. A first control module is in data communication with the first imaging device to determine contour information for an object in the field of view of the first imaging device and report the contour information for the object in a common coordinate system. A second control module is in data communication with the second imaging device to determine contour information for the object in the field of view of the second imaging device and report the contour information for the object in the common coordinate system. Moreover, the light source subsystem is calibrated to report position of the point of light in the common coordinate system.

摘要： A sensor system for analyzing a feature in a sensing volume. The sensor system includes a laser source and a sensor. The first laser source projects a laser line into the sensing volume and onto the feature forming a laser stripe on the feature. The sensor images the laser stripe where the laser line intersects with the feature. The relationship between the sensor and the first laser source is precalibrated. The sensor uses the laser stripe to determine the position and/or orientation of the feature.

摘要： A structured light sensor system for measuring contour of a surface includes a control module that coordinates control of both a projection system and an imaging system to operate the structured light sensor system in three different modes. The imaging system is configured to selectively capture an image of light reflected off of the surface. In point mode, the imaging system is on for a first period during which the projection system projects a point of light onto the surface. In line mode, the imaging system is on for a second period during which the projection system projects onto the surface a first plurality of points of light forming a line of light. In area mode, the imaging system is on for a third period during which the projection system projects onto the surface a second plurality of points of light forming a plurality of lines of light.
