Returns the internal and external parameters of the learned camera model.
Reference to the image containing calibration information.
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 the output image.
Learned coefficients of the polynomial model.
Type of distortion model learned.
Name | Value | Description |
---|---|---|
none | -1 |
No distortion model was learned. |
polynomial | 0 |
A polynomial distortion model was learned. |
division | 1 |
A division distortion model was learned. |
Learned coefficients of the polynomial model.
Learned radial coefficients of the polynomial model.
Learned tangential coefficients of the polynomial model.
Learned kappa coefficient of the division model.
Focal length learned and optical center of the camera model.
Boolean value that specifies insufficient information.
Possible conditions for insufficient information are the number of different projection planes is fewer than 5, the angle difference of the projection planes is less than 20 degrees, or the lens in use is a telecentric lens.
TRUE | One or more insufficient data conditions present |
FALSE | Sufficient data |
Focal length in pixel units.
Use the following equation to obtain the focal length in real-world units: focal length in millimeters = focal length in pixels x pixel size in millimeters. Refer to your camera documentation to obtain the pixel size.
Focal length in x direction.
Focal length in y direction.
Optical center in image.
X resolution of the optical center.
Y resolution of the optical center.
Output that indicates the projection matrix, also known as the homography matrix, of the working plane.
Error information.
