The number of servings is displayed.

Optionally, the method further includes:

The acquired motion track is played animated.

Optionally, the method further includes:

Draw a diagram of the number of servings.

In a second aspect, a statistical system for the number of tees in a tennis match is provided, the system comprising:

An acquisition unit for acquiring a movement track of the tennis ball;

a calculating unit, configured to calculate the number of servings of the tennis ball according to the motion trajectory and the running time;

A display unit for displaying the number of tees.

Optionally, the system further includes:

A playing unit for playing the acquired motion track by animation.

Optionally, the system further includes:

A drawing unit for plotting the number of servings.

Beneficial effect

The technical solution provided by the specific embodiment of the present invention acquires the motion trajectory of the tennis ball, calculates the number of serve balls of the tennis ball according to the motion trajectory and the running time, and displays the number of the serve balls, so that it has the advantage of effectively calculating the ball speed.
