The manner which decides the position and direction of the target the machine visual sense calibration target and inside the image

摘要

(57) Abstract Machine visual method two or analyzes the calibration target of the die which possesses the field above that, for example as for each field differs from the contiguity field such as color, contrast or brightness, it possesses image conversion possible property. Each field at least to have two edges (being called the contiguity edge,), those direction of the datum point to face in the straight line, in the datum point (for example center, or other position of target) cap optionally. Manner of this invention includes the image generation of the target, responds to the contiguity edge and identifies image form, matches the straight line those edges, decides the direction of the target and the both or one side of position from those straight lines.
