Definitions

  • the present invention relates to a method for measuring the movement path of an object and more particularly, to a ball movement path measuring method.
  • an immovable measuring reference when wishing to know the movement path of an object such as golf ball or baseball ball that experiences a force during a ball game training or measurement, an immovable measuring reference must be established.
  • the ball may be set in an apparatus that has a fixed measuring axis.
  • US6,551,194 entitled “Captive ball golf practice tee with three-dimension velocity and two-axis spin measurement” teaches measurement of movement and rotation of ball caused by a force by means of a fixed measuring axis.
  • This measuring method can obtain some basic data required.
  • the fixed measuring axis limits the degree of freedom of the ball when the ball experiences a force.
  • the measured data may be deviated from the possible condition of movement when the ball experienced a force.
  • the present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a ball movement path measuring method, which enables the object to move freely when experiences a force, thereby obtaining the data of XYZ acceleration data, XYZ vector components of force and torsion force relative to each of XYZ axes that are close to the actual condition of movement of the object.
  • a ball movement path measuring method comprises the steps of preparing an operating unit and a measurement unit, the operating unit being an electronic apparatus having computing and display functions, the operating unit having stored in a memory therein the weight and size data of the object to be measured, the measurement unit being a triaxial accelerometer connectable to the operating unit and adapted for transmitting the measured data to the operating unit; mounting the triaxial accelerometer in the object to be measured for enabling the triaxial accelerometer to define XYZ triaxial space coordinates; obtaining the data of a initial position of the XYZ axes at a first measuring time and transmitting the data to the operating unit, and then obtaining the data of a reference position of the XYZ axes at at least one second measuring time and then transmitting the data to the operating unit; comparing the reference position to the initial position and calculating the XYZ acceleration data and the XYZ vector components of force and the torsion force relative to each of the XYZ axes after receipt of force subject
  • ball movement path measuring method in accordance with the present invention comprises the steps as follows:
  • the triaxial accelerometer C is set in the object O to be measured, as shown in Fig. 1 .
  • the triaxial accelerometer C is located on the center of gravity of the object O.
  • the triaxial accelerometer C is moved or rotated, its internal microstructure is changed, causing a capacitance variation, which is then converted into a specific output voltage signal for output.
  • the triaxial accelerometer C defines XYZ triaxial space coordinates, as shown in FIG. 1 . Because the triaxial accelerometer C is fixedly mounted in the object O , the generation of the XYZ triaxial space coordinates defines the positions of different parts of the object O in the space.
  • the timeline positions of the first measuring time and the second measuring time and the length of time between the first measuring time and the second measuring time can be determined subject to different settings.
  • the first measuring time can be set at a time point prior to the object experienced an external force
  • the second measuring time can be set at 0.5 second after the object experiences an external force.
  • first measuring time can be set at 0.1 second after the object experienced an external force
  • the second measuring time can be set at 0.5 second after the object experienced an external force.
  • the setting of the predetermined length of time can be the data measured from the start point till the end point of a predetermined length of time started from the time moment the object is stricken by a force. For example, measure the start position before the object experiences a force, and then measure the reference position 0.5 second after the object experienced a force. Alternatively, it can measure the data continuously after the object experienced a force.
  • the first measuring time can be a time point before the object experiences a force and the second measuring time can be any time point 0.1 second after the object experienced a force, or, the first measuring time can be a time point before the object experiences a force and the second measuring time, third measuring time and etc.
  • the measurement at the second measuring time, third measuring time and etc. can be performed five times at a time interval of 0.02 second within the length of time 0.1 second.
  • the triaxial accelerometer C can be connected to a connection line through a connection port B thereof to obtain the necessary working power from an external power source and to output the measured data.
  • the triaxial accelerometer C can be made having a built-in battery and adapted for outputting the measured data by a wireless transmission method.
  • the acceleration, flight path, flight duration, and direction and angle of rotation can be obtained through a computation.
  • the measuring method of the present invention eliminates the problem of a fixed measuring axis i.e., eliminates the factors that limit free movement of the object. Further, it is not necessary to reposition the object and to reset the reference position upon each calculation.
  • the measuring method of the present invention can obtain data close to the actual movement of the object, assuring high accuracy of evaluation of the acceleration, flight path, flight duration and angle and direction of rotation of the object when the object experiences a force.
