US 2019/0294870 A1 · GESTURE TRACING DEVICE, GESTURE RECOGNITION DEVICE AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM

Abstract

A gesture recognition method and related device. The method includes following steps. A current-frame image captured by a camera in a non-visible environment is obtained in response to detecting that an object enters a recognition range. The current-frame image is determined whether it contains a gesture by performing feature image detection on the current-frame image. If yes, feature points of the gesture in the current-frame image are obtained, and the gesture is traced according to the feature points to obtain gesture tracing data. And then the gesture tracing data is transmitted to a head mounted display device. The head mounted display device recognizes the gesture according to the positions of the feature points of the gesture to obtain a gesture recognition result; and perform a corresponding response action according to the gesture recognition result.

Dependent claims

A non-transitory computer-readable storage medium storing at least one computer program which, when executed by a processor, causes the processor to carry out actions:

obtaining a current-frame image captured by a camera in a non-visible environment in response to detecting that an object enters a recognition range;
determining whether the current-frame image contains a gesture by performing feature image detection on the current-frame image;
if yes, obtaining feature points of the gesture in the current-frame image, and tracing the gesture according to the feature points to obtain gesture tracing data;
transmitting the gesture tracing data to a head mounted display device to cause the head mounted display device to recognize the gesture according to the gesture tracing data and perform a corresponding response action.
