Abstract
The utility model discloses a musical instrument simulation training and evaluation system based on action recognition. The system comprises a host machine, a display connected to the host machine, a camera which is connected to the host machine and is aimed at a human body, a simulated piano and wrist bands worn at the hands of the human body. The simulated piano is internally provided with a central processing module and a wireless module which is connected to the central processing module. Each key of the simulated piano is internally provided with a pressure sensor which is connected to the central processing module. The central processing module in the simulated piano is communicated with the host machine through the connected wireless module. Each of the wrist bands is internally provided with a central processing unit and is internally provided with an inertial measurement unit and a wireless module which are connected to the central processing unit. The central processing unit in each of the wrist bands is communicated with the host machine through the connected wireless module. The system can effectively assist a player to simulate and train music playing, and the performance of the player can be evaluated in real time.
Description
Technical field
The utility model relates to the field of human-computer interaction based on video, is specially a kind of musical instrument simulated training and evaluating system based on action recognition.
Background technology
based on the motion identification device of the video handle by the built-in sensitive device, main frame, display, the formations such as action recognition module, can be by the moving image of the camera collection human body in motion identification device, and by integrated image algorithm chip, moving image is resolved, form the Three-Dimensional Dynamic coordinate of human motion, synthetic and the emulation through the image of main frame, show at last corresponding action in display, therefore can be used as the utility appliance of musical instrument simulated training based on the motion identification device of video, but still there is no musical instrument simulated training and evaluating system based on action recognition in prior art.
