PURPOSE: A method for measuring a ball movement path is provided to obtain data which is close to the actual moving state of an object by measuring the vector component and the torque of each shaft. CONSTITUTION: A three-axis accelerometer(C) is set within a measured object(O). A three-axis accelerometer changes an electrical capacitance value by varying an inner fine structure, converts the inner fine structure, and transmits a signal to the outside while revolving and moving by itself. The memory that data about the weight and size of a measured object is built in is arranged in an operation unit. A measurement unit transfers data, which is measured at the three-axis accelerometer, to the operation unit. The three-axis accelerometer is set within the measured object and defines the space coordinates of XYZ 3 shafts. The start position data of 3 shafts is acquired in a first measurement position and is transferred to the operation unit. Comparison position data, in which 3 shafts are placed, is acquired in one or more second measurement positions and transferred to the operation unit. |
