Embodiment 1
[0092] The invention provides a billiards motion process detection, storage and replay display method, such as figure 1 shown, including:
[0093] Step 1. Obtain the induced ball pressure of the billiard table, and obtain the motion track of the billiard ball based on the induced ball pressure, and at the same time, obtain the motion track data based on the motion track;
[0094] Step 2, analyzing the motion track data, converting the analysis result into a dynamic image, and storing the dynamic image;
[0095] Step 3. Calling and simulating the stored dynamic image, and realizing the redisplay of the movement process of the billiard ball.
[0096] In this embodiment, the sensed ball pressure may be based on a pressure sensing chip under the billiard ball table, and the billiard ball is squeezed against the table during the movement of the billiard ball, thereby measuring the sensed ball pressure.
[0097] In this embodiment, the analysis of the motion track data is to obtai...

[0104] Combining the reference position information and the starting point information of the billiard ball with the orientation value and acceleration value of the billiard ball when it is moving, to obtain the movement track of the billiard ball.
[0105] In this embodiment, the middle bottom pocket of the billiard table is used as a posit...
Embodiment 3
[0108] On the basis of Embodiment 1, the present invention provides a billiards movement process detection, storage and redisplay method, before analyzing the movement trajectory data, it also includes:
[0109] Obtain the sampling frequency and the acquisition signal in the collected motion trajectory data, and convert the time domain data of the motion trajectory data into frequency domain data;
[0110] Establishing a relationship between the filter window length and the main frequency of the acquisition signal according to the information of the frequency domain data;
[0111] At the same time, according to the relationship between the filter window length and the main frequency of the acquisition signal, the optimal filter window length is extracted;
[0112] Segmenting the optimal filter window length to obtain a sub-filter window length, and obtain a wavelet coefficient matrix corresponding to the sub-filter window length;
[0113] Calculate the average value of the wa...
