Real-Time Automated Simulation Generation Based on CAD Modeling and Motion Capture

This paper describes the design, implementation and evaluation of lowcost motion capture systems with the support of hardwaresoftware interfaces for realtime automated simulation generation using CAD models. To capture the motions of 3D objects in a physical environment, stereo vision systems are developed using two kinds of inexpensive, offtheshelf cameras: 1) Wii Remote (Wiimote) and 2) Firefly MV. In this paper, we present the system’s architectural design, the software developed to implement and integrate several existing algorithms, and effective approaches to addressing practical issues such as camera calibration, object identification, and registration between the realworld and virtualworld coordinate frames. Application examples have been developed to demonstrate realtime automated generation of simulations of assembly operations using Siemens NX software for CAD modeling.
