Then, we can run multiple cameras calibration as
```
multiCameraCalibration multiCalib(cameraType, nCamera, inputFilename,patternWidth, patternHeight, showFeatureExtraction, nMiniMatches);
cv::multicalib::MultiCameraCalibration multiCalib(cameraType, nCamera, inputFilename,patternWidth, patternHeight, showFeatureExtraction, nMiniMatches);
multiCalib.run();
multiCalib.writeParameters(outputFilename);
```
Here ```cameraType``` indicates the camera type, ```multiCameraCalibration::PINHOLE``` and ```multiCameraCalibration::OMNIDIRECTIONAL``` are supported. For omnidirectional camera, you can refer to ```cv::omnidir``` module for detail. ```nCamera``` is the number of camers. ```inputFilename``` is the name of a file generated by ```imagelist_creator``` from ```opencv/sample```. It stores names of random pattern and calibration images, the first file name is the name of random pattern. ```patternWidth``` and ```patternHeight``` are physical width and height of pattern. ```showFeatureExtraction``` is a flags to indicate whether show feature extraction process. ```nMiniMatches``` is a minimal points that should be detected in each frame, otherwise this frame will be abandoned. ```outputFilename``` is a xml file name to store parameters.
