Real-time motion generation method for continuous and linear human leg walking with controllable step lengths

Abstract

The invention discloses a real-time motion generation method for continuous and linear human leg walking with controllable step lengths. The method comprises the steps of (1) three-dimensional human motion modeling, wherein the geometric structure of a virtual human leg joint chain is set, and a leg motion model of virtual human linear walking is built according to a Boulic walking model; (2) single-step step length sequence setting; (3) determination of single-step motion posture sequences with different single-step step lengths; (4) real-time generation of the walking motion posture sequences, wherein walking motion posture sequences in the virtual human linear walking process are generated according to the single-step step length sequences set in the step (2) and the single-step motion posture sequences with the different single-step step lengths, and the single-step motion posture sequences are determined in the step (3). The real-time motion generation method is simple in steps, reasonable in design, convenient to implement, good in using effect, capable of controlling the step lengths by controlling the single-step step lengths, and capable of achieving smooth transition between the adjacent changed step lengths of the walking motion.

Description

technical field [0001] The invention belongs to the technical field of human body animation production, and in particular relates to a motion generation method for continuous linear walking of human legs with a real-time controllable step length. Background technique [0002] In the production of human body animation, an important task is to produce continuous walking motions of virtual humans that are suitable for the virtual environment. The animation production of human walking movement requires walking movement data, which is a kind of high-dimensional time-varying data with coordination characteristics, and it is very difficult to generate such data manually. A continuous walking motion can be expressed as: M(t)={P(t), T(t)}, where M(t) represents walking motion, t represents time, P(t) represents the posture of the human body at time t, T(t) represents the position of the human body at time t, and T(t) is determined by the foot support constraint and P(t), where the f...

AI Technical Summary

Problems solved by technology

Since the Boulic walking model is a free walking model without foot support constraints, it describes the continuity and coordination of the P(t%) element change in M(t%), but lacks the human body position element T(t%) precise control, there are many limitations in actual use
