Color Checker
In the Feature Finding Drawer
The Color Checker tool compares a known, trained color with the average color within an ROI of an input
image. Impact software uses a 24-bit color system.
Enable Output Blob
List
When true, the filtered blobs are presented in the Blob List output
Enable Output Area
List
When true, the filtered blobs areas are presented in the Area list output
Enable Output Cen-
troid List
When true, the filtered blobs centroids are presented in the Centroid list
output
Output Origin Type Also see “Output Origin” on page 3-70
Centroid X, Y Only: The X and Y coordinates of the blob centroid (the
angle is ignored)
Centroid X, Y and Major Axis Angle: The X and Y coordinates of the
blob centroid and Major Axis angle in a +/- 90 degree range (useful if
blob has an oblong shape).
No Origin: No origin is presented (tool runs faster)
Centroid X, Y, and Major Axis Angle 360 Range: The X and Y coordi-
nates of the blob centroid and Major Axis angle in a 360 degree range
Filter Single Blob This filter is applied after all the other filters
Off: Blobs are filtered and output according to all filter settings
Centermost Blob: Only the blob closest to the center of each ROI is out-
put
Largest Blob: Only the largest blob in each ROI is output
Note: If Centermost or Largest blob is selected, only passed blobs will be
displayed in the image window.
Output Name What it is
Number of Blobs
Found
The number of blobs found
Output Blob List List of found blobs
Output Area List List of the areas of the filtered blobs
Output Centroid List List of the X and Y coordinates of the centroid points of the filtered blobs
Passed If true, the number of blobs in the Output Blob List falls within the range
of the Required Number of Blobs
Output Origin Rela-
tive to Tool
The X and Y coordinates and angle of the found origin point relative to
the Tool Origin.
Output Origin Rela-
tive To RWC
The found origin point (and angle if selected) relative to the entire image
space.
