With the gradual improvement of the immersion and experience of virtual reality products and the increasing abundance of virtual reality video content and game content, the virtual reality rapidly permeates in industrial applications such as manufacturing, education, culture, tourism and the like, and a 'platform + application' closed-loop ecological circle which is win-win by three parties of hardware merchants, consumers and developers is formed. The virtual reality industry presents the good development situations that virtual reality terminal products are all flowers together, technology and service upgrading innovation, key technology is continuously broken through, and product and industry standards are mature. At present, VR technology is applied to medical treatment, military, science and technology, commerce, building, entertainment, life and the like. However, the factors that the actual movement and the brain movement cannot be normally matched due to the fact that the existing hardware can not highly restore the visual contrast in the VR product and the VR interface of a real scene, the picture sense of the VR content is not in accordance with the actual situation, and the inter-frame delay of the VR equipment cannot follow the movement of people, so that a user feels dizzy and cannot experience the user for a long time, and therefore, the VR dizzy problem is solved, and the main technical problem in the industry at present is solved.
