 | 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. |
Calibration Tab
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. |
Simple Calibration
| 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. |
User Points Calibration
| 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. |
Grid Calibration
| 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. |
Calibration from Image
| 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. |
Axis Tab
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. |
