Document Type and Number:
WIPO Patent Application WO/2022/166243
Kind Code:
A1
Abstract:
A method for detecting and identifying a pinching gesture. The method is applied to an electronic apparatus, and comprises: acquiring, in real time, each frame of image data in a video to be tested (S110); performing hand positioning detection on the image data on the basis of a pre-trained hand detection model, and determining a hand position in the image data (S120); performing bone point identification on the determined hand position on the basis of a pre-trained bone point identification model, and determining a preset number of bone points at the hand position (S130); and determining, according to preset distance information between bone points of fingers, whether a hand corresponding to the image data shows a pinching gesture (S140). By means of the method, a gesture of a user can be quickly and accurately detected and identified, thereby improving the user experience for an artificial reality system.
