Abstract

The invention provides a method for estimating the proportion of virtual hand bones in a pow transformation simulation VR system which analyzes the skeletal structure of the hand by kinematics, and simplifies the human hand skeleton model. Based on real-time attitude angle data of inertial sensors, combined with the statistical value of hand skeletal length in anatomy as the skeletal length of virtual hand, two special postures are calibrated respectively, and the skeleton ratio of human hand is calculated. According to the different structure of user's hand, the skeleton ratio of virtual handis adaptively changed to realize the fine reappearance of virtual hand to user's hand movement, and the virtual hand is driven to realize the training of substation simulation, and the virtual hand in the substation simulation virtual environment is driven to complete the corresponding action. The method realizes the initial deviation correction of the sensor data and reduces the error in the process of hand fine motion tracking caused by the influence of the individual hand proportion difference of the user.

Description

technical field [0001] The invention relates to the technical field of power transformation simulation, in particular to a method for estimating the proportion of a virtual hand skeleton in a power transformation simulation VR system. Background technique [0002] The substation is an important part of the power system. With the improvement of its automation, higher requirements are put forward for the operation and maintenance personnel. As a means of information transmission and communication, virtual reality technology can intuitively and realistically provide users with visual information such as equipment structure, operating procedures, and abnormal performance. basic conditions and strong guarantees. Using virtual reality technology and computer simulation technology to construct a suitable visual virtual environment to replace physical prototypes for training can effectively overcome the limitations of time, venue and safety brought about by using actual equipment f...
