Primary, Secondary, Perpendicular Edge Pattern
The tool ROIs detect patterns of transition from dark to light (rising) or light to dark (falling), depending on
this property. For instance, the setting "Rising Only" finds only transitions in the image that change from
dark to light. The found pattern is also affected by the "...Object Color to Find" property. The origin is
located on the first transition of the selected type.
Alternating Falling/Rising: Detects both dark to light and light to dark transitions
Rising Only: Detects only dark to light transitions
Falling Only: Detects only light to dark transitions
Subpixel Method The type of subpixel averaging
The grey levels of one or more adjacent pixels (3, 5, 7, or 9) around an
edge point are used to interpolate the edge to a fraction of a pixel
Subpixel Position The subpixel position for edges that are not well defined. See “Subpixel
Position” on page 3-144.
Subpixel Search
Distance in Pixels
The maximum distance, in pixels, that the subpixel algorithm searches
from the threshold edge for the subpixel edge. See “Subpixel Search
Distance” on page 3-125.
Use Reference Ori-
gin
If True, the Reference Origin is used to determine the Output origin.
Reference Origin This is the desired position for the Origin on the displayed image. Move
the Reference Origin to the desired position on the image, then press the
Train button. The tool calculates the offset between the current found
Origin and the Reference Origin, and use that offset for all subsequent
found origins.
Output Name What it is
Success If True, an origin was found
Output Origin Rela-
tive to Tool
The found origin, relative to the Tool Origin, if any.
Output Origin Rela-
tive To RWC
The found origin, relative to the entire image space.
Primary Points
Found
The point used on the Primary ROI to determine the origin.
Secondary Points
Found
The point used on the Secondary ROI to determine the origin
Perpendicular
Points Found
The point used on the Perpendicular ROI to determine the origin
Points Found A list of points found on all ROIs
Relative ROI Origin The origin based on Relative ROI positioning. (See Relative ROI Posi-
tioning Method property)
