Abstract:
1. Method for connecting corresponding points measured by a computer vision system in a set of points, said method comprising the steps of: calibrating cameras and illuminator used in a system; determining a location and orientational position of an object; illuminating points on the surface of the object; imaging the illuminated points by the camera system; connecting corresponding points imaged by different cameras; calculating actual three-dimensional coordinates of the object on the basis of the corresponding points; and storing the coordinates in memory; wherein the method further comprises the steps of: performing a calculation whereby two-dimensional projection points corresponding to the desired measuring points are determined in the images from a three-dimensional model of the object; searching an area near the calculated point in the images produced by the cameras to locate the actual point imaged; connecting the actual point perceived by different cameras as a corresponding point; and repeating the procedure for all the illuminated points.
