Arc Caliper Arc Caliper The Arc Caliper tool identifies and measures the gap between one or more edge pairs of arc- shaped objects. Edges can be disposed in a radial or an annular position. The Arc Caliper uses pixel grey-level values within the region of interest to build projections needed for edge detection. After detecting potential edges, the Arc Caliper determines which edge pairs are valid by apply- ing the constraints that are configured for each edge pair. Finally, the Arc Caliper scores and measures each valid edge pair. To create an Arc Caliper tool, right-click in the Tree structure, then select:
