Abstract

In this paper, a non-image gesture recognition control system based on convolutional neural network is designed and implemented. This system uses MPU6050 gyroscope to collect time series acceleration sensor data and identify the user gesture action through one-dimensional convolutional neural network (1D CNNs). The system aims to solve the problem of inaccurate recognition of traditional image gesture recognition methods in low illumination and complex background environment.

The design uses STM32F103CBT6 as the master chip to realize the acquisition, processing and recognition of gesture data, and the control of external devices based on the recognition results. The system integrates the RF remote control and Bluetooth communication module, which can recognize the gesture library containing 10 gestures, such as specific letters and numbers, and the correct recognition rate is controlled at more than 90%. In addition, the system is highly scalable, allowing users to add new gestures or function modules as needed. This study not only improves the accuracy and adaptability of gesture recognition, but also provides new ideas and methods for the application of non-image gesture recognition technology.
