However, it cannot be denied that there is a serious imbalance in the allocation of education resources in our country, and education resources in economically lagging areas are significantly deficient, and even in a city, the level of education is generally higher in economically developed counties and worse in economically undeveloped counties. With the development of 5G and computer technology, the current situation of unbalanced resource allocation can be properly relieved by performing classroom education through VR. In designing a VR smart educational system, designers need to be alerted to new resource allocation unfair problems that new technical means may cause, for example, if rendering work for VR classrooms is performed locally, each classroom needs to be configured with high-computing-capacity computers, which is very costly in the current state of the art. If the VR teaching system is implemented in this way, the new system and teaching philosophy exacerbates the problem of unfair education instead. In order to avoid the problem, a mode of rendering a VR scene by a cloud end is needed, and aiming at the requirements of the prior art, the application provides a virtual reality education scene data transmission method and system based on cloud end rendering.
