Abstract
Disclosed herein are a device and method for sensing a moving ball configured to analyze continuously acquired images of the moving ball and to calculate information about the spin of the moving ball based on the analysis result. It is possible to calculate the spin of the moving ball without providing a specific marker on the ball. In the case in which a logo or a brand mark is present on the ball, or in which dimples or cracks, which are feature portions in an image, are also present on the ball, it is possible to easily, rapidly, and accurately calculate the spin of the moving ball using the same.
