Inputs (4)
| Name | Type | Default | Description |
|---|---|---|---|
| cameraMatrix | NPARRAY | - - - A data array (points / matrix), NOT an image - only an NPARRAY link is accepted here. | |
| imageSize | CV_TUPLE | 0,0 | One value with 2 components (w, h) - it travels as a whole, so it cannot arrive half-connected. Wire it from 'CV Tuple' or type the components in place. |
| apertureWidth | FLOAT | 0.0000-1e+38–1e+38 | - - - |
| apertureHeight | FLOAT | 0.0000-1e+38–1e+38 | - - - |

| Name | Type | Description |
|---|---|---|
| fovx | FLOAT | — |
| fovy | FLOAT | — |
| focalLength | FLOAT | — |
| principalPoint | CV_TUPLE | - - - Subpixel coordinates (x, y) as ONE composite value - wire it straight into any cv2 point input, or into 'CV Split Tuple' for the separate numbers. |
| aspectRatio | FLOAT | — |
