Embodiment
[0128] In order to analyze the virtual maintenance method of typical faults of complex equipment, study the modeling and simulation technology of complex equipment fault maintenance process, and build a virtual maintenance training simulation system for a certain type of equipment. In this system, the operator realizes the interactive control of virtual human movement in the virtual maintenance environment by using hardware equipment such as mouse, keyboard, 5DT Data Glove 14 Ultra data glove, space position tracking device and three-dimensional projection system. Take the motion control method of the virtual human body at the initial moment of the simulation platform as an example to illustrate the effect:
[0129] At the initial moment t of the simulation running platform running s , the virtual human body presses image 3 The direction shown is facing the 3D model of a maintenance object b, where the spatial position V of the root node mkr_1 of the virtual human body is b...

The invention relates to a real-time interaction virtual human body motion control method in virtual maintenance simulation. Limited input information acquired by a single data glove and a single sensor in a space position tracking device is utilized to conduct real-time interaction control on virtual human body motion; according to main operation motion in virtual maintenance and functions of VR interaction peripherals, the relationship between the origin of a virtual human body coordinate system and initial coordinates of a certain articulation point of a virtual human body is defined, and the virtual human body coordinate system transversely moves and rotates along with motion of the human body correspondingly; local articulation reference coordinate systems are built on all articulation points respectively. Compared with the prior art, the real-time interaction virtual human body motion control method changes the conditions of the cost of machine and equipment performance and complex methods, achieves smooth virtual human body motion control, is small in operand, does not have high requirements for software and hardware environments, can conveniently achieve real-time interaction control under the condition that the single data glove and the space position tracking device only provided with the single sensor are used, reduces development cost and difficulties, and improves development efficiency.
Description
technical field [0001] The invention belongs to the technical field of data processing. It relates to a real-time interactive control method for virtual human motion in virtual maintenance simulation, and in particular, in the case of limited virtual reality interactive equipment, using a single data glove and limited input information obtained by a single sensor in a spatial position tracking device to control the virtual human body. A method for real-time interactive control of motion. Background technique [0002] Virtual human motion control is an important process to realize the action interaction between product parts model, maintenance resource model and virtual maintenance human body in virtual maintenance operation. The fidelity, real-time, interactivity and accuracy of this process directly affect and determine the virtual maintenance. The effect of training operations. At the same time, it is also the reproduction of the operation actions of maintenance personne...
