[0032] Please refer to Figures 1-4 , the embodiments of the present invention provide the following technical solutions:

[0033] Embodiment 1.

[0034] A digital Guozhuang dance motion capture and analysis system, comprising a Guozhuang dance capture and analysis platform 1 composed of a motion capture module 2 and a frame image processing module 3. Among them, the motion capture module 2 includes a video recording and generating unit 201, an artificial screening unit 202, a frame image extraction unit 203, and an information storage unit 204. The video recording and generating unit 201 is used to obtain the dancing process of Guozhuang dance dancers through an infrared high-speed camera and generate a Guozhuang dance video. It should be noted that before the Guozhuang dance dancers start dancing, luminous marking points are added to the joints of the dancers;

[0035] The video recording and generating unit 201 is connected to the artificial screening unit 202. The artificial screening unit 202 is used for professional review of the Guozhuang dance video by Guozhuang dance experts, screening out non-standard Guozhuang dance videos, and obtaining standard Guozhuang dance videos;

[0036] The artificial screening unit 202 is connected to the frame image extraction unit 203. The frame image extraction unit 203 is used to extract the frame images of the Guozhuang dance video;

[0037] The frame image extraction unit 203 is connected to the information storage unit 204. The information storage unit 204 is used to store the frame images of the Guozhuang dance video and arrange and store them in chronological order.

[0038] As a preferred solution, the motion capture module 2 is connected to the frame image processing module 3. The frame image processing module 3 includes a joint coordinate acquisition unit 301, a coordinate change capture unit 302, and an orientation marking unit 303. The joint coordinate acquisition unit 301 is used to obtain the coordinates of the luminous marking points in the frame image as joint coordinates;

[0039] The joint coordinate acquisition unit 301 is connected to the coordinate change capture unit 302. The coordinate change capture unit 302 is used to simulate the motion curve of the joint coordinates according to the chronological change as the joint position change curve and store it in the information storage unit 204;

[0040] The coordinate change capture unit 302 is connected to the orientation marking unit 303. The orientation marking unit 303 is used to identify the change orientation according to the joint coordinate change direction in adjacent frame images and store it in the information storage unit 204.

[0041] In this embodiment, the digital recording of the Guozhuang dance standard is realized, providing a reliable guarantee for the recording of the Guozhuang dance.

[0042] Embodiment 2,

[0043] As an improvement over the previous embodiment, a digital Guozhuang dance motion capture and analysis system further includes a node analysis module 4. The frame image processing module 3 is connected to the node analysis module 4. The node analysis module 4 includes a custom frame extraction unit 401, a video recombination unit 402, and a hierarchical storage unit 403. The custom frame extraction unit 401 is used to extract frame images at a set interval from the frame images stored in sequence, as reference Guozhuang dance nodes, and obtain the change azimuth identifiers of adjacent reference Guozhuang dance nodes, and add the change azimuth identifiers to the frame images corresponding to the previous reference Guozhuang dance nodes.

[0044] The custom frame extraction unit 401 is connected to the video recombination unit 402. The video recombination unit 402 is used to recombine the video of several reference Guozhuang dance nodes in sequence to obtain a frame-extracted image video.

[0045] The video recombination unit 402 is connected to the hierarchical storage unit 403. The hierarchical storage unit 403 is used to determine the difficulty level of the Guozhuang dance according to the number of frame images at the set interval. Among them, the larger the number of frame images at the set interval, the lower the difficulty level of the Guozhuang dance; conversely, the smaller the number of frame images at the set interval, the higher the difficulty level of the Guozhuang dance.

[0046] The advantages of the second embodiment over the first embodiment are as follows: While ensuring the continuity of the video by means of frame extraction, it can also reduce the dance details of the Guozhuang dance, provide a standard for the systematic difficulty classification of the Guozhuang dance, enable learners to complete the learning of the Guozhuang dance quickly and efficiently, and provide effective support for the spread of the Guozhuang dance.

[0047] The digital recording method of the Guozhuang dance using the above system includes:

[0048] S1. Add luminous marking points at the joints of the dancer. The video recording generation unit 201 obtains the dancing process of the Guozhuang dance dancer through an infrared high-speed camera to generate a Guozhuang dance video. The Guozhuang dance expert conducts a professional review of the Guozhuang dance video through the manual screening unit 202, screens out the non-standard Guozhuang dance videos, obtains the standard Guozhuang dance video, extracts the frame images of the standard Guozhuang dance video through the frame image extraction unit 203, arranges and stores them in sequence, and stores them in the information storage unit 204.

[0049] S2. The joint coordinate acquisition unit 301 acquires the coordinates of the luminous marking points in the frame image as joint coordinates. The coordinate change capture unit 302 simulates the motion curve of the joint coordinates according to the sequential change as the joint position change curve. The azimuth marking unit 303 marks the change azimuth identifier according to the joint coordinate change direction in adjacent frame images and stores it in the information storage unit 204, where the change azimuth identifier is marked in the previous frame image and at the corresponding joint coordinates.

[0050] When using the above system for Guozhuang dance teaching, the difficulty of Guozhuang dance is divided, and the specific methods include:

[0051] Set a set number of frame images at intervals through the custom frame extraction unit 401, and then extract the set number of frame images from the frame images arranged and stored in time sequence as the reference Guozhuang dance nodes, and obtain the change orientation identifiers of adjacent reference Guozhuang dance nodes, and add the change orientation identifiers to the frame images corresponding to the previous reference Guozhuang dance nodes. The video recombination unit 402 performs video recombination on a number of reference Guozhuang dance nodes in time sequence to obtain the frame extraction image video. The grading storage unit 403 determines the difficulty of the Guozhuang dance according to the number of the set number of frame images at intervals. Among them, the larger the number of the set number of frame images at intervals, the lower the difficulty of the Guozhuang dance; on the contrary, the smaller the number of the set number of frame images at intervals, the higher the difficulty of the Guozhuang dance;

[0052] During the process of learners learning the Guozhuang dance from the high-difficulty level to the low-difficulty level, they can first master the overall dance framework of the Guozhuang dance, provide effective support for the spread of the Guozhuang dance, and then perform video recombination by re-filling the extracted frame images to achieve the detail supplement of the Guozhuang dance, ensuring the integrity and learning quality of the Guozhuang dance.
