Arc Edge Locator Related Topics Arc Caliper Tool Configuring Arc Caliper Properties Configuring Arc Caliper Properties - Advanced . Arc Edge Locator The Arc Edge Locator tool identifies and measures the position of one or more edges on a cir- cular object. Edges can occur in a radial or an annular position. The Arc Edge Locator uses pixel grey-level values within the region of interest to build pro- jections needed for edge detection. ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 371 Object Definition Pair Radius Mean of Edge 1 Radius and Edge 2 Radius. Pair X The X coordinate of the center point of the caliper measure, at the midpoint of the edge pair.
Pair Y The Y coordinate of the center point of the caliper measure, at the midpoint of the edge pair. Frame/Group The frame or group to which the result belongs. Edge 1/Edge 2 Score The score of the individual edge, calculated accord- ing to the defined constraints. Edge 1/Edge 2 X The X coordinate of the edge, at the midpoint of the edge segment. Edge 1/Edge 2 Y The Y coordinate of the edge, at the midpoint of the edge segment. Edge 1/Edge 2 Rotation The angle of rotation for the edge. Edge 1/Edge 2 Radius Radius of detected arc. Edge 1/Edge 2 Position Score Position score for the edge, calculated according to the Position constraint function.
Edge 1/Edge 2 Magnitude The calculated Magnitude value for the edge. Edge 1/Edge 2 Magnitude Score Magnitude score for the edge, calculated according to the Magnitude constraint function.
