Abstract


With the development of simulation and virtual reality technology , virtual human technology has gradually become a hot topic of current research . Virtual human research to reflect the characteristics of the human geometry and behavior as the main objective , the research can be divided into the geometric model of the virtual human virtual motion control , virtual human behavior expression , and the four main aspects of virtual human cognitive expression . The first two studied from the point of view of the geometry and behavior characteristics of the virtual human verisimilitude latter two aspects are studied mainly from the point of view of the virtual human society and intelligent . This article the former two aspects that geometric modeling and motion control of virtual human technology in-depth study , the main job of the work of the following aspects : First, the establishment of a virtual geometric model . Analysis of the human body structure , simplified motion capture human skeleton in the document type definition combined , create a virtual human model has 45 joint geometric model of the virtual human representation of the human skeletal system , with points layer modeling method to establish realistic virtual geometric model . Secondly , in terms of motion control technology , research a variety of motion control method , analyzing the queue of operating characteristics , and to establish a model of human motion . Detailed study of motion capture and the kinematics control methods , virtual human action control . In order to deal with motion capture data , connected motion mixing the digital signal processing method and a motion redirection technology has been studied , and gives detailed algorithm description of the motion in the motion editing techniques . Finally , according to the research of this article on the human body geometric modeling and motion control method in the environment of VC 6.0 and Vega design and development queue training simulation system . The simulation and experimental results show that the established geometric model of the human body is realistic and credible , the combination of motion capture and kinematics motion control method is effective , realistic virtual human control . Based the the virtual queue training system can be used as adjunct of traditional the queues training methods , help improve the trainees ' enthusiasm , improve training efficiency and level of training . At the same time , the study also later studies lay the theoretical and technical basis .
