Determination method and device for human hand skeleton parameters, electronic equipment and storage medium

Abstract

The invention relates to a determination method and device for human hand skeleton parameters, electronic equipment and a storage medium. The method comprises the steps of collecting a target hand type; determining a coordinate C # ij of a jth generation child node on each finger in the target hand shape in a world coordinate system; and calculating a rotation matrix R'ij of the local coordinate system CS'ij relative to the local coordinate system CS'i (j-1) in the human hand skeleton according to the incidence relation between the coordinate C'ij and the coordinate C # ij of the jth generation child node in the rotated target hand shape in the local coordinate system CS'ij. A target hand shape of a rotation matrix is determined so that the target hand shape does not need to be manually drawn; instead, the embodiment can be directly adopted to construct the association relationship between the coordinate Cij and the coordinate C'ij, and the rotation matrix of each node in the target hand type relative to the father node is automatically determined according to the association relationship, so that the reduction of manual participation in the process of determining the rotation matrix is facilitated, and the cost and time consumption are reduced.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to a method, an apparatus, an electronic device and a storage medium for determining human hand skeleton parameters. Background technique [0002] At present, when 3D rendering generates human hand composite data, human hand skeleton parameters are required, wherein the human hand skeleton parameters refer to the rotation matrix of each node (also called key point) relative to the parent node of the node, and the rotation matrix can represent the node. The direction of the line connecting to its parent, the rotation angle relative to the direction of the line between the parent and the parent's parent. Among them, the parent node of a node refers to: a finger along the direction from the fingertip to the wrist, a node point in front of a node. [0003] For example, a node on a human hand skeleton can be as figure 1 As shown, taking node 10 as an example, its...
