For the command... Apps > Stereo Camera Calibrator > Add Images ..what file type does it expect, for the checkboard pattern?

I printed out the Matlab checkboard pattern. Should I take a still or a video? What file extension is expected?

Stereo Camera Calibrator app takes still images. It will take any image format that imread can handle. It is best, however, to store your calibration images in a format like PNG or TIFF, that does not use lossy compression. JPEG compression introduces artifacts, which will negatively affect the checkerboard corner detection accuracy.
