Object of color counting
You can use the object of color counting function to count the number of object in a certain color.
Area means the number of pixels in a certain color.
User designates color to inspect from the target, and registers area to be inspected.
Object of color counting inspects the number of object in a certain color in the registered ROI.
It regards object with the certain amount of pixel as an object, and compares the number of
detected object. The number of detected object within the pass range is regarded as Pass, while
the number of detected object out of the pass range is regarded as Fail.
No. Item Description
1 Pass range
It sets the pass/fail range for inspecting the teaching color ( ) in
the ROI area ( ).
Lower limit The measured number of Upper limit
for pass object of color in ROI for pass
2
Color deviation
mode
※
1
It sets mode to measure color deviation.
Color deviation mode is calculating method of pass range for the input
image based on the registered ROI average color value.
Depending on the color deviation mode, specific setting is different.
3
Color deviation
mode
- specific setting
Euclidean distance deviation Manhattan distance deviation
Color deviation threshold:
It sets pass range based on the
ROI average color.
Red/Green/Blue:
It sets pass range by applying
deviation value to each of red,
green, blue color.
4
ROI average
color
It displays average color of ROI in a data value, depends on the set
color system (color area) mode.
