Research On Technology Of Software Platform To Dynamic Scene Generate

Based on dual-channel screen projection virtual reality system of North University ofChina simulation laboratory, build a set of dynamically generated visual software platform,solved the problem of virtual scene constructed and generation in the similar system. Thisplatform has a very good portability, and functional aspects also easy to expand, in the samekind of multi-channel curved screen projection display system plays an important role. Thispaper research content is as follows:(1)Introduces the general hardware architecture of dual-channel curved screen projectionvirtual reality system at the North University of China simulation laboratory, Aiming at theshortcoming of Master/Slave structural in software deployment, we propose a pre-readingmaster/slave software architecture as the improvement proposal.(2)Study the key technique and problems of multi-channel curved screen projectionvirtual reality system, Including geometric correction, channel segmentation, grating splicing,edge fusion technology and synchronization technology of software and hardware, Aiming atthe problem of geometric calibration for multichannel-curved screen projected displaysystem，a correction algorithm was proposed based on dynamic texture segmentation.(3)Research the scene building technology and the related problem, including the logicaland physical structure of scene storage and import of model file, etc. Finally, we completedthe design and development of the visualized virtual scene constructed and managementsystem.(4)System introduce the transmission data cache from master to slave, moving speed androtating perspective of the observer model, creation object of listener and the buffer inthree-dimensional sound space, polarization stereo vision technology and other relatedtechnologies. Against these issues, we completed the design and development of a dynamicscene generation platform.
