Embodiment 1

[0063] Such as figure 1 and figure 2 As shown, the intelligent prosthetic hand adopts the three-freedom prosthetic hand as the intelligent prosthetic hand body, which includes finger parts, palm parts, residual arm parts, power supply and memory modules for power supply, wherein each finger in the finger parts is at each joint And the wrist place that connects palm part and residual arm part is all provided with motor, is used for driving each joint of each finger and the rotation of wrist place.

[0064] On the above-mentioned three-freedom prosthetic hand body, there are also a voice interaction module 1, a depth camera module 2, an LED touch screen 5, a wireless communication module 6, a wireless charging module 7, a core processing module 8, a power supply 9, and a myoelectric signal sensor 10 and memory module 11, wherein,

[0065] The voice interaction module 1 is used to realize the voice interaction function. By collecting voice information and performing preliminar...

Embodiment 2

[0086] Such as Figure 4 As shown, the Internet of Things intelligent prosthetic hand system based on voice control and visual recognition is composed of a cloud server, a secondary operation terminal, and an intelligent prosthetic hand that are connected wirelessly.

[0087] The intelligent prosthetic hand adopts the intelligent prosthetic hand in Embodiment 1.

[0088] The secondary operation terminal includes a client installed on a smartphone or computer for controlling an intelligent prosthetic hand, and / or a motion capture glove, wherein,

[0089] The client can establish a wireless connection with the cloud server and the intelligent prosthetic hand; the client has a built-in 3D model of the prosthetic hand, and the user can input data to accurately adjust and determine the gesture, which is converted into a machine control code by the client; the client can be connected to a motion capture glove to obtain Motion model, analyze the motion information of the motion mode...

Embodiment 3

[0103] This embodiment provides a method for realizing gesture actions based on the Internet of Things intelligent prosthetic hand system of Embodiment 2, including the following steps:

[0104] Step 1: Take pictures of two-dimensional scenes and objects through the depth camera component of the intelligent prosthetic hand, and upload them to the cloud server;

[0105] Step 2: Call the image recognition interface of Baidu AI Open Platform through the cloud server to perform recognition, and send the recognized corresponding objects and scenes to the core processing module of the intelligent prosthetic hand;

[0106] Step 3: The core processing module combines the identification information of the cloud server and compares the usage of each gesture in the past to infer the gesture that is most likely to be used;

[0107] Step 4: Send the inferred gesture action to the LED touch screen for the user to choose;

[0108] Step 5: Feedback the data selected by the user to the core p...

Abstract

The invention discloses an intelligent prosthetic hand based on voice control and visual recognition, a system and a method thereof, belonging to the technical field of prosthetic hands. The intelligent prosthetic hand adopts a three-degree-of-freedom prosthetic hand body, and further comprises a depth camera module, a voice interaction module, an LED touch screen, a core processing module and a wireless charging module, wherein, the depth camera module is used for acquiring image data; the voice interaction module is used for voice interaction with the user; the LED touch screen is used for user to input operation instruction and display data; and the core processing module implements the overall task scheduling and data processing. The invention also discloses an intelligent prosthetic hand system and a gesture movement realizing method on the Internet of Things. The intelligent prosthetic hand based on voice control and visual recognition solves the technical problems that the existing mainstream prosthetic hand only relies on myoelectric control and traction control, so that control efficiency is low, and myoelectric signal interference is large, and operation and training arecomplex, and solves the technical problems that the voice control function is single and complex gesture operation cannot be completed, and intelligence is low.

Description

technical field [0001] The invention belongs to the technical field of prosthetic hands, and more particularly relates to an intelligent prosthetic hand based on voice control and visual recognition, a system and a method thereof. Background technique [0002] The smart prosthetic hand can complete the compensatory function of the prosthesis by driving the opening and closing of the prosthetic hand and the movement of the wrist and elbow joints through a DC micro-motor, which can provide convenience for the daily life of disabled patients with missing upper limbs and improve the quality of life. It is of great value in research in the field of rehabilitation engineering. Existing prosthetic hand products are divided into forearm myoelectric prosthesis with single degree of freedom and two degrees of freedom and upper arm myoelectric prosthesis with two degrees of freedom and three degrees of freedom. The first two degrees of freedom are low, and many scenarios are not appli...
