Human Modelling and Design of Spatio-Temporal Queries on 3D Video Database
Takashi Tomii, Kiril Salev, Sayaka Imai, Hiroshi Arisawa · 1998
This paper presents a concept of a 3D Video Database, called Real World Database (RWDB), in which not only image and audio data but also object structure, behavior, temporal event and all spatial occasions are stored uniformly. In this presentation, we will concentrate ourselves into the factory workers’ modelling and simulation for the virtual manufacturing systems. Using RWDB, we designed the human body structures, motions in a work and events over them. As a result, it can evaluate various motions of workers and pursue the optimum design of works. Also a functional data manipulation language MMQL for spatio-temporal inquiry is offered. This enables us to evaluate the posture and safety of workers based on the calculation of positions of spatial objects.
