Search a pattern in the image and store it.
[in] | image | An image or a videoframe. |
|
inline |
Calibrate the camera.
[in] | max_used_patterns_count | Maximum number of patterns to use for calculation. If more patterns are accepted, the subset covering the pattern space best will be used. The recommended value is 50. |

Correct the image distortion using the calibrated or loaded camera parameters.
[in] | image | An image or a videoframe. The size can differ from the size of the images used for calibration. I.e. you can calibrate a camera once with one resolution and then calibrate the distortion of images from the same camera with any resolution. |
[in] | alpha | A real value from 0 (the result image contains only valid pixels (no black areas)) to 1 (all pixels from the original image are stored in the result image (no source image pixels are lost)). Intermediate values yield an intermediate result between those two extreme cases. |
