The invention discloses a gesture recognition system based on a virtual interaction device. The system is used for solving the problem of how to utilize mutual contact of finger tips and recognize respective gestures, the influence of illumination and angles and low recognition rate is low are avoided, and the aim is to research how to eliminate unused gestures in the gesture database and how to use gestures to realize unlocking verification. The system comprises a data acquisition module, a preprocessing module, a gesture recognition module, a processor, a display module, an execution module,a virtual interaction device, a software recognition module, a gesture switching module, a gesture storage module and a gesture editing module. Through judgment of mutual contact of the finger tips,a gesture instruction is formed and is not influenced by illumination and angles, and the recognition accuracy is high; instructions which can be identified and executed correspondingly by the exchange device are identified through the gesture identification module; a deletion value Ei is obtained by using a formula shown in the specification, wherein Tik is greater than Tgd; and unused gesturesin the software gesture database are removed by comparing the deletion value Ei of the software type Di.
Description
technical field [0001] The invention relates to the technical field of gesture recognition of a virtual interaction device, in particular to a gesture recognition system based on a virtual interaction device. Background technique [0002] Gesture recognition is a topic in computer science and language technology that aims to recognize human gestures through mathematical algorithms. Gestures can originate from any body movement or state, but typically originate from the face or hands. Current focus in this field includes emotion recognition from facial and gesture recognition. Users can use simple gestures to control or interact with devices without touching them. The recognition of poses, gaits and human actions is also the subject of gesture recognition technology. Gesture recognition can be seen as a way for computers to understand human body language, thereby building a richer bridge between machines and humans than raw text user interfaces or even GUIs (graphical user...
