Microwave radar technology-based gesture recognition device and gesture recognition method

Abstract

The present invention belongs to the information technological field and relates to a microwave radar technology-based gesture recognition device and gesture recognition method. The gesture recognition device comprises a signal transmitting-receiving module, a data processing module and a gesture recognition module; the signal transmitting-receiving module is used for periodically transmitting microwave radar signals to a preset range, and receiving radar echo signals reflected by hands; the data processing module is connected with the signal transmitting-receiving module and is used for acquiring the feature information of gestures according to the radar echo signals; and the gesture recognition module is connected with the data processing module and is used for identifying the gestures according to the feature information acquired by the data processing module. With the above gesture recognition device and gesture recognition method adopted, the defects of existing gesture recognition can be eliminated, and a more natural and intelligent interaction mode can be realized.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a gesture recognition device and a gesture recognition method based on microwave radar technology. Background technique [0002] In recent years, with the rapid development of smart homes and wearable devices, computing devices are ubiquitous and integrated into people's living environment. In order to facilitate the interaction between people and computing devices, it is necessary to propose a more natural interaction method that allows users to get rid of the dependence on input devices as much as possible, such as air gestures, compared with the traditional contact-based human-computer interaction method. Air gesture is a kind of non-contact air gesture that enables users to operate with bare hands. Its essence is a natural human-computer interaction method that does not bring any inconvenience to user gesture interaction. [0003] Air gestures allow users to express the...

Problems solved by technology

However, due to its weak robustness and high signal-to-noise ratio requirements, further research and solutions are needed; radar electromagnetic waves are not affected by light, noise, and the environment, and can penetrate most materials. To build a fast response, high precision object movement monitoring and tracking system

However, how to overcome the inherent attenuation, multipath, collision and other problems of the electromagnetic signal itself, and how to design a more effective machine learning model, are still challenges in practical applications
