Description

A 5G-based data teaching system for multimedia dance studios

technical field

The invention relates to the technical field of dance teaching, in particular to a data teaching system for a 5G-based multimedia dance studio.

Background technique

Dance teaching is the behavior and process of enabling the educated to master dance knowledge, learn dance skills, and improve dance ability through various methods. There are three mainstream forms of dance teaching, namely: traditional on-site teaching, distance teaching and dance teaching video teaching. In the information age, compared with on-site teaching, distance teaching provides great convenience for everyone. However, for dance-related courses (except for dance theory courses), distance teaching seems to be difficult to meet the needs-all students get the same image and sound, regardless of their foundation, strengths and weaknesses. The interaction between students is also a big problem. The learning of dance movements cannot be effectively assisted and corrected in distance teaching. In the process of dance teaching, teachers need to guide students' dance movements, control music and video playback, and may need to record in-class teaching videos after class. Students often need to watch teacher's demonstration videos as a comparison when practicing. Therefore, in reality, distance teaching is often widely used as a supplement to on-site teaching. With the popularization of dance culture, the requirements for supporting facilities in dance teaching and practice are gradually increasing. Higher-quality distance teaching requires corresponding dance studios to achieve high-quality distance teaching, and better integration of multimedia and its control technology into dance classrooms is a technical problem that needs to be explored and solved in this area.

At the same time, relying on relevant resources and conducting a large number of related experiments, after a large number of searches, we found existing technologies such as KR101003676B1, CN102444298B, US20160260347A1 and KR101811806B1 , the teaching system disclosed in the prior art generally includes a screen dance room system involving an image storage unit, an audio unit, a controller, a large mirror, a projector, a screen image unit, and a left and right inversion unit for inverting the left and right sides of an image . In addition, a screen image unit is provided at the rear of the practitioner, and a large mirror is provided at the front, and an image storage unit, a loudspeaker, a large screen image unit, and a projector for providing audio and images are also provided, wherein the The large mirror is arranged in the front part of the exerciser, and the screen image unit is located behind the exerciser, or inside the mirror, so that the exerciser can see through the mirror at the same time His/her practice screen and dance practice image in the same state sideways. The dance studio teaching system in the prior art has a low level of intelligence, and most of them are aimed at one-person teaching, so the practicability is low.

In order to solve the uneven quality of data teaching systems on the market that are common in this field, it is impossible to realize dance teaching and scoring monitoring for multiple people in the dance room at the same time, and it cannot automatically sense the number of people in the laboratory to guide the movement, and the shooting device has dead angles. Can not photograph the specific dance movement of the student that road is blocked by other people, intelligent degree is relatively low etc. problem, have made the present invention.
