Smart preschool education live streaming: VR-driven optimization strategy.

The construction of smart city has become the frontier trend of city development. Smart education shows the inner beauty of smart city, and smart education is the connotation extension of educational informatization. At present, smart education has become an important symbol of education modernization worldwide, which is an important way to improve the quality and efficiency of education, cultivate innovative talents, and is the inevitable choice to realize the leap-forward development of education. Furthermore, preschool education is a critical period for the rapid development of children's nervous system. Education in this period plays a decisive role in children's development and is also a necessary condition for their development of intelligence and potential. However, traditional teaching cannot guarantee the fun of children's teaching activities. According to the characteristics of multi-sensory, immersive, and interactive virtual reality (VR) technology, VR is introduced into the live demonstration application of preschool education. Since VR video contains information in all directions of a scene, its data volume is much larger than that of traditional video, and different panoramic video projection layout schemes have a great impact on the quality of video. To solve this problem, a continuous layout method based on octahedral projection is proposed, which eliminates the internal discontinuous edges and has good boundary continuity. Experimental results show that the layout method proposed in this paper has good performance in both video quality and computing cost, which provides power for VR technology in the live demonstration of preschool education, and increases the immersion and comfort of children when watching VR videos.
