Hi,

Although the Camera Calibrator App supports only the checkerboard image, you can calibrate your camera and find the cameraParams using the estimateCameraParameters function. In order to do so, you are required to supply your own code to detect the pattern points in the image.

More details on using the above-mentioned function can be found here: https://www.mathworks.com/help/vision/ref/estimatecameraparameters.html
