ABSTRACT:
The invention relates to connection of corresponding points measured by a computer vision system. The points are indicated by an illuminator (LASER), by means of which several points can be illuminated on the surface of the object at the same time. A camera system (CAM1, CAM2) measures the positions of the points. Using a data system (DTE), projection images are generated from a three-dimensional model of the object, in which images the positions of the points are calculated. To locate the actual point in the image perceived by the cameras, a search is performed in an area in the neighborhood of coordinates calculated from the point in the projection image. The point thus located can be connected to the perceptions of the other cameras by the aid of the projection images. After the corresponding points have been found, the actual three-dimensional coordinates of the measured point are calculated.
