ABSTRACT:
An image processing system uses the digital expression of the video image of a light stripe derived optically from a seam to create a 1-D signal representative of a one-pixel wide line. The target coordinates for the tool operating on the seam is converted directly into 3-D tool position and orientation from the 1-D signal. Matching with models is effected in real time by comparing symbolic attributes of the graphs built up with the 1-D signal and with standard seams. From such matching is selected the operative corner, or target for the tool.
