Contour Matching and Planar Alignment using Optimal Transformation Parameters
In industrial automation systems, it is of immense importance to ensure precise and accurate positioning of a part
to meet sustained quality requirements. The proposed algorithm minimizes planar translation and rotation errors during
positioning of an object in a typical production process Disoriented object contour information was extracted using the
existing image pre-processing methods. The proposed algorithm, determines the unknown planar translation and rotation
parameters of the transformation matrix, that maps the template object contour points to the corresponding disoriented object
points. Another algorithm for contour matching is coupled with parameter identification method to correct the arbitrary start
location for the disoriented object contour points.
