Abstract:
The invention provides an apparatus and a method for measuring a dimension of a circular object. First to third sensors arranged in a straight line are disposed above a track to respectively measure time instants when the circular object moves past the first to third sensors. The dimension of the circular object is calculated according to distances between the first and second sensors and between the second and third sensors.
