Currently, the main shooting equipment used for circular-screen movie production is the multichannel reflective camera system. However, this equipment is cumbersome, the playout method is complex, and the cost of production is very high. To overcome these shortcomings, this study proposes a panoramic video method for producing circular-screen movies. Three key problems of using the panoramic video...
Multi-channel visual reality system based on PC cluster can give users strong sense of immersion. This paper discusses the synchronous problem in multi-channel visual reality system. For the viewpoint synchronization, this paper brings forward a message communication mechanism based on change of user operating status. This mechanism can reduce the message amount by a large margin, so the message block...
The virtual reality application usually involves automatic roaming. Camera instability is a problem that occurs frequently to automatic roaming, resulting in abrupt change and jittering of vision field. In this paper, a method based on Cardinal spline interpolation is proposed to solve this problem. Given the path controlling points, we first compute a set of high-density interpolate points through...
With the virtual knee arthroscopy training software system and the hardware device of interaction, this paper discussed a solution of real-time interaction based on PCI-1711(Peripheral Component Interconnect) data acquisition card. The solution achieved real-time multi-sensor signals acquisition by PCI-1711 data acquisition card, then processed the signals on VC platform and transmitted them into...
