Problems solved by technology

Therefore, in the early stage of piano performance learning, more professional piano teachers are needed to provide guidance. However, due to many reasons, these guidance often fail to achieve the expected results. For example, the level of piano tutors is uneven, and the quality of learning is difficult to guarantee; Teaching resources are tight, and most piano learners lack supervision when practicing alone. If the hand posture is wrong and cannot be corrected in time, not only the practice effect will not be achieved, but the healthy development of their own piano skills will also be affected

Embodiment 1

[0036] Such as figure 2 As shown, in one embodiment of the present invention, a kind of piano supervisory method is provided, is applied to above-mentioned computer equipment 20, and this method comprises:

[0037] Step S201, acquiring a depth image of the playing area through an image acquisition device;

[0038] In one embodiment of the present invention, a depth image is also called a distance image, which refers to an image that uses the distance (depth) from the image acquisition device to each point in the scene as a pixel value, and it directly reflects the geometry of the visible surface of the scene. Shape; the depth image can be calculated as a point data set (referred to as point set) after coordinate conversion, that is, point cloud data (point cloud is a mass point set with target surface characteristics), point cloud data with rules and necessary information can also be Inversely computed as depth image data.

[0039] Generally, the point cloud obtained accord...

Embodiment 2

[0135] like Figure 7 As shown, in one embodiment of the present invention, a kind of piano supervision device is provided, and described piano supervision device is used for:

[0136] An image acquisition unit 210, configured to acquire a depth image of the playing area through an image acquisition device;

[0137] A hand gesture acquiring unit 220, configured to acquire player's hand gesture information according to the playing area depth image;

[0138] The recognition unit 230 is configured to use a trained neural network classifier to recognize the hand posture information, and determine whether the posture corresponding to the hand posture information is correct;

[0139] The output unit 240 is configured to output the judgment result to the player.

[0140] This embodiment is a virtual device corresponding to the piano supervision method, and the content involved is the same as that of Embodiment 1. For details, please refer to the description of Embodiment 1, which w...

Embodiment 3

[0142] Figure 8 An internal block diagram of a computer device in one embodiment is shown. Specifically, the computer device may be figure 1 The computer equipment 20 in. like Figure 8As shown, the computer device includes a processor, a memory, a network interface, an input device, and a display screen connected through a system bus. Wherein, the memory includes a non-volatile storage medium and an internal memory. The non-volatile storage medium of the computer device stores an operating system and also stores a computer program, and when the computer program is executed by the processor, the processor can realize the piano supervision method. A computer program may also be stored in the internal memory, and when the computer program is executed by the processor, the processor may execute the piano supervision method. The display screen of the computer equipment may be a liquid crystal display screen or an electronic ink display screen, and the input device of the com...

Abstract

The invention is applicable to the field of piano playing, and provides a piano monitoring method and device, a computer device and a storage medium. The method comprises the following steps of acquiring a depth image of a playing area by an image acquisition device; acquiring hand posture information of a player according to the depth image of the playing area; using the trained neural network classifier to recognize the hand posture information and judging whether the posture corresponding to the hand posture information is correct or not; and outputting the judgment result to the player. Based on the application of the depth image and the artificial neural network, the invention realizes the judgment of the hand movement of the piano player, thereby realizing the uninstructed supervision of the hand movement / posture of the piano player / learner, saving a large amount of resources and improving the piano teaching efficiency.

Description

technical field [0001] The invention belongs to the field of piano teaching, and in particular relates to a piano supervision method, device, computer equipment and storage medium. Background technique [0002] With the continuous improvement of living standards, the piano has entered thousands of households. However, it is not easy to become an excellent pianist. Piano learners need a lot of training to improve their level to a satisfactory level. Degree. [0003] The professional requirements of piano performance are very high. Among them, whether the fingering, hand posture and other hand postures are correct is particularly critical. Once the foundation is distorted in the early stage, it is quite difficult to correct it in the later stage, and some people even waste all their previous efforts. Therefore, in the early stage of piano performance learning, more professional piano teachers are needed to provide guidance. However, due to many reasons, these guidance often f...
