Estimation of Curling Sheet Friction Factor by Pixelization

This study estimates the coefficient of friction on the actual curling sheet with a pebble, without having to mount any devices on it. Existing studies have equipped the ice sheet with external devices to estimate the coefficient of friction. Another paper estimated friction coefficients, assuming that the pebble did not exist, because it was very difficult to estimate the coefficient of friction in the space where the pebble was located. In this study, it is possible to estimate the coefficient of friction of the actual curling sheet without fitting an external device onto the curling sheet. In addition, the friction coefficient estimation method attempted using image processing techniques may be most similar to the actual friction coefficient, reducing the outside influence, compared to the existing papers. It will also be an estimation method using image processing techniques, which form the basis of various friction coefficient screening methods.
