Abstract

The invention discloses a virtual hand grasp simulating method based on motion capture. The method includes the following steps of building a correct virtual hand skeleton model according to physiological anatomical properties of a real human hand; building a skeleton kinematic model via the virtual hand skeleton model; importing the skeleton kinematic model into a test platform, carrying out impact test between the virtual hand and an object according to a classification method expressed by a 3D (three-dimensional) model and a level bounding box ; obtaining a torsion spring model and a drawing force spring model of a nonlinear spring model according to a linear spring model, and calculating five grasping forces of each finger; obtaining a resultant force of each finger by combining the five grasping forces respectively for each finger, and providing a rendered result of the resultant force; judging whether the rendered result of the resultant force satisfies an ergonomic test or not, ending the steps on yes; and adjusting a corresponding product on no until the product satisfies the ergonomic test. The virtual hand grasp simulating method based on motion capture is capable of shortening the production cycle and reducing the product cost.

Description

technical field [0001] The invention relates to the field of virtual reality technology, combines virtual hand interaction technology in virtual reality and ergonomics technology in industrial product design, and particularly relates to a virtual hand grasping simulation method based on motion capture. Background technique [0002] Virtual reality technology can allow users to have a real experience in the virtual scene as in the real world, and provide users with real visual and sound effects. In recent years, with the gradual rise of research on haptic and force feedback, this will give virtual reality The user can bring a more excellent real experience, and the comprehensive use of motion capture equipment and force feedback equipment can allow users to grasp virtual objects in the virtual scene, and at the same time, the hand can feel the force received when grasping. [0003] The hand is the most flexible organ in the human body. Human flexibility is perfectly expressed...
