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 system and method for identifying significant bivariate checkpoints. The system includes a controller configured to receive measurements for a plurality of checkpoints and calculate the covariance and correlation for each checkpoint pair. The controller identifies significant bivariate checkpoints based on the covariance between the checkpoint pairs. Further, the controller may also calculate the correlation for each checkpoint pair and identify the significant bivariate checkpoints based on a combination of the covariance and the correlation between the checkpoints. Further, the controller may rank the significant bivariate checkpoints and provide the significant bivariate checkpoints to a principal component algorithm.
