Hand action identification method and apparatus, computer device and readable storage medium

Abstract

The invention relates to a hand action identification method and apparatus, a computer device and a readable storage medium. The hand action identification method comprises the following steps of collecting an image of a to-be-identified object through an image collection apparatus, and inputting the image of the to-be-identified object to an initial human body model to obtain pose information ofthe to-be-identified object; selecting position information of wrist joints from the pose information, and according to the position information of the wrist joints, obtaining a hand region image; andinputting the hand region image to a preset hand action model to obtain a first hand action of the to-be-identified object. According to the method, an overall pose of an identified person is identified firstly and then a hand is located; and when multiple to-be-identified objects exist in an identification region and are mutually shielded, the hand positions can be judged according to the posesof the to-be-identified objects, so that the hand action identification accuracy is improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a hand motion recognition method, device, computer equipment and a readable storage medium. Background technique [0002] With the advancement and development of computer technology, human-computer interaction has become a requirement in people's lives. In addition to traditional interaction methods such as mouse and keyboard, gesture interaction has also become a mainstream as technology matures. [0003] Traditional hand tracking algorithms are based on vision algorithms. In color images, hands are identified based on skin color and other features for tracking. Recently, with the popularity and popularity of depth cameras, there are also many works that combine depth image information to perform hand movements. identification and tracking. However, if there are multiple people in the scene, the difficulty of hand recognition and tracking will be greatly increased, and misjudgment and...
