Abstract
Virtual reality technology is an emerging technology developed on the basis of information technology. It is widely used in military, medical, mining, entertainment, and other fields. Therefore, many countries have been vigorously conducting research in recent years. As one of the important components of the virtual reality system, the three-dimensional human motion tracking system is of great significance to the research of practical virtual reality systems. It introduces the measurement principle of the spatial three-dimensional coordinate dynamic measurement device and discusses in detail the ultrasonic transmission, reception, amplification, filtering, comparison, shaping circuit, and single-chip interface circuit. This paper introduces the working principle and characteristics of the virtual experiment system and gives the structure diagram, hardware schematic diagram, and software flow diagram of the system. We mainly study the method of tracking human motion by measuring the three-dimensional coordinates of the space point, which lays a good foundation for the research of the actual three-dimensional motion tracking system. At the same time, the three-dimensional human body modeling is discussed, and the interactive movement policy of the human arm is briefly introduced. It has a certain effect on the actual virtual reality human-computer interaction system.
Highlights
Virtual reality (VinuaI Reality abbreviated as VR) is a comprehensive view with computer technology as the core
Hearing and touch are integrated, imitating the reproduction technology of the real three-dimensional space [1]. e goal of VR technology is to use a computer to generate a simulated environment that can highly realistically simulate the various characteristics of the user in the natural environment
With the continuous development of VR technology, computer graphics, and network technology, three-dimensional space has been introduced into the Internet, transforming the web from a page-centric model to interaction with three-dimensional, dynamic, and realistic world. en, we form the second generation of web technology [3]
