Detects circular dots in a binary image and returns the pixel and real world points for calibration.
Refines the location of circular dots using a supplied grayscale image.
ROI to be corrected.
Coordinates of the bounding rectangle.
Individual shapes that define an ROI.
Object specifying if contour is the external or internal edge of an ROI.
Shape type of the contour.
Relative position of the contour.
Image containing circular dots.
Corresponding grayscale image containing dark circular dots, for refining the location of the cirular dots in the target image.
Spacing between dots in the grid in real-world units.
Width of a pixel in real-world units.
Height of a pixel in real-world units.
Unit for X Step and Y Step.
The following options are valid:
Name | Description |

Number of dots to use in the x and y direction. Specifying 0 for Max X and 0 for Max Y uses all dots in the grid.
Number of dots in the grid in the x direction.
Number of dots in the grid in the y direction.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Reference to target image.
Locations of the grid dots used as reference points to learn a calibration.
Coordinates of the pixels found in the image.
X-coordinate of the point.
Y-coordinate of the point.
Relative locations of the dots in the real world.
X-coordinate of the point.
Y-coordinate of the point.
Unit of the Real World Coordinates.
Size of the calibration template image.
Horizontal size of the image.
Vertical size of the image.
