Description

Field

Increases in increments of 4 pixels (for example, 1, 5, 9, 13, ...) up to the total

FOV size. Some things to note:

ROI Width

• Narrow ROIs execute faster but could miss the edge.
• Wide ROIs are more consistent but don't execute as fast.
• The ROI must be 13 pixels or wider to calculate the rotation of a part.

Runs a rolling average along the ROI length. It filters out sharp changes in the

edge profile.

Smoothing

Note:

A high filter number may miss the edge of a narrow line.

Filters out small spike-of-intensity changes, and narrow dark or bright bands. It

determines the distance (in pixels) before and after an edge that must be free from

additional transitions or the end of the ROI before the edge is recognized.

Min Width

Note:

A high filter number may miss the edge of a narrow line.

Determines the sub-pixel resolution, which increases the resolution of the tool,

and increases the inspection time.

Sample Rate

1. 1-pixel resolution
2. 1/2-pixel resolution
3. 1/3-pixel resolution
4. 1/4-pixel resolution

Object Width

Object Width filters out objects and spaces that are smaller than the minimum and larger than the maximum values

specified.

The minimum and maximum object width affects both objects and spaces between objects. Minimum object width

can filter out objects and spaces.

Object Tool Results

The Results field returns the following:
• The position of the object midpoint. The origin (0,0) is the upper-left corner of the screen.
• A Select Object Number field for selecting an object to analyze.
• Total number of Bright, Dark, or All objects (depending on the Bright/Dark option in effect.
• Distance between the edges of the current object.
