Title:
WEIGHT-REDUCED HAND JOINT PREDICTION METHOD AND DEVICE FOR IMPLEMENTATION OF REAL-TIME HAND MOTION INTERFACE OF AUGMENTED REALITY GLASS DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/255642
Kind Code:
A1
Abstract:
According to a weight-reduced hand joint prediction method and device for implementation of real-time hand motion interface of an augmented reality glass device proposed in the present invention, candidate key points of hand joints are detected from a whole input image without a hand detection process, and then at least one hand joint included in the input image is predicted on the basis of a correlation between the candidate key points by using a joint evaluation model. Therefore, the present invention allows prediction of a plurality of hand joints by one-time candidate key point detection without a separate hand area detection and a joint prediction process in each of detected hand areas and thus can simplify and reduce a hand joint prediction process, and can prevent a joint prediction time and an operation quantity from increasing in proportion to the number of hands in the input image and thus enables rapid hand joint prediction in real time in an embedded environment.
