Embodiment 1
[0092] The present invention provides a billiards motion process detection, storage and replay display method, such as Figure 1 shown, including:
[0093] Step 1, to obtain the induction ball pressure of the table, and based on the induction ball pressure to obtain the motion trajectory of the billiard ball, at the same time, based on the motion trajectory to obtain the motion trajectory data;
[0094] Step 2, the motion trajectory data is parsed, and the parsing result is converted into a dynamic image, and at the same time, the dynamic image is stored;
[0095] Step 3: The stored dynamic image is called to simulate, and the movement process of the billiard ball is displayed repeatedly.
[0096] In this embodiment, the induction ball pressure may be a pressure sensing chip under the table based on billiards, during the movement of billiards, squeezing with the table, thereby measuring the induction ball pressure.
[0097] In this embodiment, the motion trajectory data is analyzed t...
Embodiment 2
[0101] On the basis of Example 1, the present invention provides a billiard ball motion process detection, storage and replay display method, to obtain a specific working process of the billiard ball motion trajectory, comprising:
[0102] Take the middle bottom pocket mouth of the table as the position reference point and obtain the reference position information of the position reference point, and at the same time, obtain the starting point information of billiards;
[0103] Based on the induction ball pressure of the table, the azimuth value and acceleration value of the billiard ball are obtained;
[0104] The reference position information and the starting point information of the billiard ball are combined with the azimuth value and acceleration value of the billiard ball movement to obtain the trajectory of the billiard ball.
[0105] In this embodiment, the middle bottom pocket mouth of the table as the position reference point, in order to obtain the starting point of th...
Embodiment 3
[0108] On the basis of Example 1, the present invention provides a billiard ball motion process detection, storage and re-disk display method, before the movement trajectory data is parsed, further comprising:
[0109] Acquire the sampling frequency and acquisition signal in the acquired motion trajectory data, and convert the time domain data of the motion trajectory data to the frequency domain data;
[0110] According to the information of the frequency domain data, the relationship between the filter window length and the main frequency of the acquired signal is established;
[0111] At the same time, according to the relationship between the filter window length and the main frequency of the acquired signal, the optimal filter window length is extracted;
[0112] The optimal filter window length is segmented, the sub-filter window length is obtained, and the wavelet coefficient matrix corresponding to the sub-filter window length is obtained;
[0113] The wavelet coefficient m...
