Abstract

The curl mechanism of a curling stone is not fully understood. We obtained sequential images of the stone movement on a curling ice sheet with two CCD cameras and estimated the curl ratio and ice friction coefficient using the image processing technology. This paper reports details of the measurement methods and results of some analyses.
