Abstract

The safety production is critical to stable development of Chinese electric power industry. With the development of electric power enterprises, the requirements of its employees are also becoming higher and higher. In this paper, an optical motion capture system based on the virtual reality technology is proposed to meet the requirements of the power enterprise for the qualified business ability. Electric power equipment, power equipment model entitative operating environment and the human model are established by electric power simulation unit, ZigBee technology and OpenGL graphics library. The problem of missing feature points is solved by applying the human model driven algorithm and the Kalman filtering algorithm. The experimental results show that it is more accurate to use Kalman filtering algorithm to extract the feature point in tracking process of actual motion capture and real-time animation display. The average absolute error of 3D coordinates is 1.61 mm and the average relative error is 2.23%. The system can improve trainees’ sense of experience and immersion.

Summary

Introduction

The safety production of electric power enterprise is an important guarantee for the development of the power industry. (2016) Application of Optical Motion Capture Technology in Power Safety Entitative Simulation Training System. These ways are usually high cost and ineffective. Onsite training has a good effect, a lot of equipment is electrically operated. With the development of Virtual Reality (VR) technology [1], simulation systems using VR technology configure virtual environments, and improve the realism of the training scenes. Simulation training software cannot simulate the real power system environments; it is a poor sense of the experience and immersion. With the optical motion capture system and electrical equipment entitative simulation training system, the trainees can feel immersive and the ability of simulation training system can be enhanced. 2.
