To train the tool’s scale factor:
1. Place the Wide Line ROI across the distance to be measured. If the ROI goes partly off the image dur-
ing runtime, it will be clipped at the image’s edge.
2. Press the Train button. Check the endpoints found to make sure the desired distance is being measured.
3. Type the known measurement distance into the Scale Factor Train Distance field.
4. Click the Train button.
The tool will calculate the scale factor required to scale the measured distance in pixels to the Scale Factor
Train Distance value.This factor is applied after any camera calibration factor.
A Setup is available for this tool, which will simplify basic configuration. Click the Setup tab to use it.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space
Wide Line ROI Points on this ROI are used for measuring. If the ROI goes partly off the
image during runtime, it will be clipped at the image’s edge.
Wide Line ROI List A list of wide line ROIs used for measuring
Distance Type Euclidean: direct distance between the points
AbsoluteX: the distance between Point One and a line through Point
Two's X coordinate and perpendicular to the X axis
AbsoluteY: the distance between Point One and a line through Point
Two's Y coordinate and perpendicular to the Y axis
Distance Tolerance If the distance between the beginning and ending measurement points
exceeds this value, the tool will fail. The parameters are minus, nominal,
and plus.
Primary Endpoint
Position
The starting point for measuring, beginning from the tail end of the ROI
Secondary End-
point Position
The ending point for measuring, beginning from the tail end of the ROI
Primary Use Center If True, the measurement starting point is half way between the Primary
and Secondary Endpoints
Secondary Use
Center
If True, the measurement starting point is half way between the Second-
ary Endpoint and the next point beyond it
Blob Color To Find Bright, Dark, or both color objects
Blob Threshold
Method
See “Grey Level Threshold Types” on page 3-68 for more details.
Fixed Blob Thresh-
old Percentage
The grey level threshold value for fixed single threshold types (in per-
centage)
Adaptive Blob
Threshold Offset
If Adaptive Threshold Method is selected, this offset is added to the
adaptive threshold. This allows you to weight the adaptive threshold up
or down.
