Skeleton attitude calculation method, character virtual model driving method and storage medium

Abstract

A bone pose calculation method, a figure virtual model driving method and a storage medium. The bone pose calculation method is the key step of the figure virtual model driving method, and comprises: based on a bone pose iterative calculation process of inverse kinematics, reversely calculating the joint angle change of an intermediate joint of a human bone chain according to the pose information change of a limb end, so that after each iteration, various joint angles are close to the best value, thereby effectively guaranteeing a smooth graduated effect when a body movement is simulated, and meeting the application requirement of realistically simulating body movement. In addition, multiple judgment mechanisms are used during an iterative calculation process, so that various joint angle changes and the pose information change of a limb end can be updated for the next iterative calculation in time, thereby simplifying the judgment process, guaranteeing the effectiveness of an iterative loop, improving the calculation speed of a system while ensuring that the calculation result is accurate, and enhancing the time relevancy of a body movement capturing process.

Description

technical field [0001] The invention relates to a motion capture technology, in particular to a calculation method for a skeleton posture, a driving method for a virtual character model and a storage medium. Background technique [0002] Motion capture technology (Mocap, referred to as Mocap) refers to setting a tracker on the key part of a moving object, and the motion capture system captures the position of the tracker, and then obtains the data of three-dimensional space coordinates after computer processing. When the three-dimensional space coordinate data is recognized by the computer, it can be applied in animation production, gait analysis, biomechanics, ergonomics and other fields. Especially in the field of movie special effects, the real-life images captured by multiple cameras are replaced with digital models to capture and record the actions of the actors during performances, and then synchronize these actions to the virtual characters in the computer, so that th...
