Calibrate Image Controls

Main Tab

The following controls are available on the Main tab.

Control Name	Description
Step Name	Name to give the step.
Calibration Type	Type of calibration you selected in the calibration wizard, either Simple Calibration, Calibration Using User-Defined Points, Grid Calibration, or Calibration from Image.
Calibrated Image File Path	Path to the calibrated image whose calibration information you use to set the calibration information of the current image.
New Calibration	Launches the calibration wizard so you can create a new calibration setup.
Edit Calibration	Loads the calibration wizard so you can change your calibration setup.
Relearn Calibration at Each Iteration	When enabled, the step relearns the calibration information at each iteration of the inspection.
Save Calibrated Image to File	When enabled, the step saves the calibrated image to the path specified in the New Calibrated Image File Path control.
New Calibrated Image File Path	File path to which you want to save the image calibrated by this step.

The following information is available on the Calibration tab.

Note The contents of the Calibration tab vary depending on the Calibration Type selected in the Calibration Wizard.

Control Name	Description
Pixel Type	Indicates whether the image has square or nonsquare pixels.
Correspondence Image - Real World	Gives the real-world size of a pixel in both the horizontal (x) and vertical (y) directions.

Control Name	Description
Calibration Points	Lists the points selected for calibration in the calibration wizard.
Image Coordinates	Coordinates of the currently selected calibration point, given as the number of pixels from the origin.
Real-World Coordinates	Coordinates of the currently selected calibration point, given as the number of Units from the origin.
Unit	Unit of measure selected in the calibration wizard.
Distortion	Type of distortion selected in the calibration wizard, either Perspective or Nonlinear.

Control Name	Description
Pixel Type	Indicates whether your image has square or nonsquare pixels.
Correspondence Image - Real World	Coordinates of the currently selected calibration point, given as the number of Units from the origin.
Unit	Unit of measure you selected in the calibration wizard.
Distortion	Type of distortion you selected in the calibration wizard, either Perspective or Nonlinear.

Control Name	Description
Pixel Type	Indicates whether your image has square or nonsquare pixels.
Correspondence Image - Real World	Gives the real-world size of a pixel in both the horizontal (x) and vertical (y) directions.

The following controls are available on the Axis tab.

Control Name	Description
Axis Origin	X- and y-coordinates of the origin you selected in the calibration wizard.
Axis Reference	Direction of the y-axis, either Direct or Indirect.
Angle Relative to Horizontal	Angle of the x-axis of the calibration axis you selected relative to horizontal.
Correct Image	When enabled, the step corrects the calibrated image by applying a calibration to create a spatially correct image.
Interpolation Type	Specifies the interpolation method to use to obtain the corrected image. The following options are valid: Zero Order (default)—Rounds to the nearest integral pixel location. Bi-Linear—Uses linear interpolation in both the x- and y-directions to compute the pixel location.
Replace Value	Specifies the value that the step uses to fill pixels in the corrected image that the step could not correct in the original image. The default is 0.
