Camera Calibration with dot chart

Hi!
Camera calibration sometimes is also performed using a dot chart/pattern or circles grid, instead of a checkerboard (cmp http://docs.opencv.org/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html#findcirclesgrid). Are there predefined functions in MATLAB that do camera calibration using dot charts? I can't find any. Maybe there also is a toolbox in fileexchange?
Thanks!

Currently there is no function in MATLAB analogous to findCirclesGrid() for detecting a pattern of circles. However, if you can detect the points yourself, you can use the estimateCameraParameters function in the Computer Vision System Toolbox to calibrate. estimateCameraParameters takes world points and the corresponding image points, regardless of the type of calibration pattern you use.
Also, you can try the OpenCV interface support package, that helps you call OpenCV functions from MATLAB.
