摘要： This invention provides accurate, high quality images for the identification of the surface characteristics of an object, that may be used as an input to suitable industrial process. It involves acquiring a first raw scan of a portion of a target object across a scan line in a scan zone with a first camera and simultaneously acquiring a second raw scan of the same portion of the target object across the scan line in the scan zone with a second camera. The raw scans are converted to digital and then processed with flattening coefficients derived from measurements of variations in illumination. The first and second cameras sets of flattened image data are then gridized to compensate for parallax, make them orthographic sets of image data that can be compared on a pixel-by-pixel basis with a known or measured geometric profile of the target. A selection of enhanced pixel value for a surface coordinate can then be made, based on both sets of data. The obscuring of surface features by specular reflection can thus be effectively eliminated.

摘要： A three-dimensional machine vision scanner head for obtaining raw scan data from a target object and an integrated scan information extraction module that performs data reduction and passes to a controller selected summary target object scan information that is significant for automated control decisions in an industrial process. The scanner head contains a laser light emitter, reflected laser light detector and a communication interface for transmitting the target object scan information from the information extraction module to the controller.
