Embodiment 1
[0053] see Figure 1 to Figure 3 , a real-time gesture recognition method mainly includes the following steps:
[0054] 1) Establish a gesture classification model and store it on the server side.
[0055] The main steps of building a gesture classification model are as follows:
[0056] 1.1) Obtain training sample data, the main steps are as follows:
[0057] 1.1.1) Use the motion sensor of the smart terminal to collect the motion sensor data of n testers, which is recorded as data set B=[B 1 , B 2 ,...,B h ,...,B m ]. B h Represents a set of motion sensor data.
[0058] The motion sensor mainly includes a three-axis acceleration sensor and a three-axis gyro sensor. The motion sensing data mainly includes three-axis acceleration data, three-axis gyroscope data and motion time.
[0059] 1.1.2) The smart terminal sends the collected motion sensor data to the server via Bluetooth. The server side is a mobile phone or a computer with data storage and processing functio...
Embodiment 2
[0103] The system based on real-time gesture recognition method mainly includes smart terminal, camera and server.
[0104] The smart terminal has a motion sensor.
[0105] The smart terminal mainly includes smart bracelets, smart watches and smart gloves.
[0106] The motion sensor collects the motion sensor data of the user in real time and uploads it to the server.
[0107] When the camera collects gesture sensing data, it records the video information collected by the gesture and uploads it to the server.
[0108] Gesture classification models are stored on the server side.
[0109] The server tags the gesture data against the video information and the motion sensor data.
[0110] The server side preprocesses the motion sensor data to obtain the resultant acceleration data a.
[0111] The resultant acceleration a is as follows:
[0112]
[0113] In the formula, x, y and z are the data of the three axes of the three-axis acceleration sensor, respectively.
