Undistort Image
In the Image Geometry Drawer
The Undistort Image tool applies the input image's calibrated distortion mapping to the image to produce an
output image that is not distorted. The tool’s primary purpose is to "flatten" an image with perspective dis-
tortion, so that images look similar at all rotations and translations. It also removes radial lens distortion. Use
this tool with the OCR and Greyscale Template tools since they do not work with severe image distortions.
This tool is not normally needed with the Blob, Gauge, and Contrast tools since the calibration process maps
edge points to uniform real-world coordinates.
X-Y Projection
In the Image Geometry Drawer
The X-Y Projection tool finds the average intensity of each column (X projection) or row (Y projection) of
an area within an ROI and then repeats that average intensity across the column or row to create a new
image. This image can then be used by other tools.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space.
Shape List The desired region of the image to search. If no shape is defined, the
entire image is processed.
Output Name What it is
Output Image The undistorted image (may be viewed on the Output Image tab).
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space.
Shape List The desired region of the image to search. For a single rectangle, the x
or y axis is projected. For circles, polygons, doughnuts, etc. the tool ori-
gin axes are projected and the row/column average intensity includes
the enabled pixels.
Projection Direction Project on X Axis: Each column is repeated
Project on Y Axis: Each row is repeated
Output Image
Thickness
The width of the output image in units in the repeated direction. Default
is zero which is ten units.
Fixed Threshold
Range
The grey level threshold range for the In Range and Out of Range
options (in percentage). The parameters are start and end.
Use In Range Value If True, pixels with a grey level within the Fixed Threshold Range are
changed to the In Range Value before the average intensity is calcu-
lated. See “Fixed Threshold Range” on page 3-66.
