As the checkerboard sequences for calibration of the Grasshopper2 cameras are shown at http://robotcar-dataset.robots.ox.ac.uk/downloads/ Does anybody knows the length of the checkerboard for calibration?

Hi, The boards are 115mm by 116.5mm (slightly different length/width), from which it should be easy to divide by the number of squares to get an estimate of the accurate size

The checkerboard is 9x7. What does "The boards are 115mm by 116.5mm" mean? It seems not consistent with the calibration image.
