Embodiment Construction

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0051] At present, the interaction gestures between the virtual hand and the parts are mostly research on the grasping rules of the virtual hand, such as the grasping rules based on the normal vector of the point contact plane, the grasping rules based on the effective threshold angle, and the deformation of these rules. However, at present, the virtual hand is not dexterous enough i...

Abstract

The present invention provides a virtual hand control method and device, the method comprising: receiving the image data sent after the hand movement collected by the gesture capture device, and extracting the hand gesture data and the graspable target object from the image data ; Update the preset hand bounding box according to the hand posture data, and construct the object bounding box according to the target object recognition data; if the collision between the hand and the target object is determined based on the hand bounding box and the object bounding box to meet the preset collision detection conditions, judge Whether the hand posture determined based on the hand posture data satisfies the preset hand posture condition; if the hand posture meets the preset hand posture condition, the center of the virtual hand created based on the hand posture data in the virtual reality scene and based on the The center of the virtual target object created by the target object establishes a fixed connection so that the virtual hand can grasp the virtual target object. It achieves the technical effect of improving the dexterity of the virtual hand in the virtual reality scene and making the grasping operation more realistic.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a virtual hand control method and device. Background technique [0002] With the development of virtual assembly human-computer interaction technology, a variety of interactive devices such as data gloves and Kinect 3D cameras have emerged, which can track and collect human body data and improve the fidelity of interaction. Among them, the hand is the most flexible organ of the human body. Introducing virtual hands into virtual assembly can complete complex assembly actions. Accurately obtaining human hand information and improving the interaction performance between hands and parts are the current research difficulties. The existing virtual hand grasping operation generally uses data gloves to input the state information of the user's hand into the computer, and uses a virtual hand to simulate the movement of the user's hand in the virtual environment, and grasp, move ...
