Data prediction method and apparatus

Abstract

The invention provides a data prediction method and apparatus. The method comprises the following steps: after motion data collected at each collection moment within a preset historical time period are obtained, obtaining a motion mode of a target object according to the motion data collected at each collection moment, selecting a prediction model matched with the motion mode of the target object and a delay parameter related to the prediction model, predicting a next frame of image data called by a virtual reality device through the prediction model according to the motion data collected at each collection moment and the delay parameter. Therefore, the next frame of image data called by the virtual reality device is predicted based on the motion data collected at each collection moment within the preset historical time period so as to reduce the image jitter and display delay, for each virtual reality device, the next frame of image data can be predicted by the technical scheme mentioned above, therefore the universality of the method is higher, and the cost of the virtual reality device is reduced.

Description

technical field [0001] The invention belongs to the technical field of forecasting, and more specifically, relates to a data forecasting method and device. Background technique [0002] Virtual reality is a kind of use of computer graphics, simulation technology, multimedia technology, artificial intelligence technology, computer network technology, parallel processing technology and multi-sensor technology to simulate the visual, auditory, tactile and other sensory organ functions of the target object (such as the user), It is a new technology that enables the target object to immerse in the computer-generated virtual realm and interact with the virtual objects in the virtual realm in real-time through language, gestures, head movements and other natural ways. [0003] With the continuous development and progress of virtual reality technology, various virtual reality applications and virtual reality equipment have emerged on the market, especially mobile phone-based virtual...

Problems solved by technology

[0003] With the continuous development and progress of virtual reality technology, various virtual reality applications and virtual reality equipment have emerged on the market, especially mobile phone-based virtual reality equipment has the advantages of low cost and portability, which is an important direction of market development at present. However, mobile phone-based virtual reality devices also have some defects. For example, the accuracy of the sensor in the mobile phone-based virtual reality device is low, resulting in a decrease in the accuracy of the data collected by the sensor, and the processor processing capacity of the mobile phone-based virtual reality device is limited. The collected data also needs to process the data required by other applications in the mobile phone, resulting in an increase in the display delay of the virtual reality device based on the mobile phone, and the decrease in the accuracy of the collected data and the increase in the display delay will further lead to image jitter and display lag

[0004] In order to solve the above-mentioned technical problems, the solution adopted at present is: improve the sensor accuracy and the mobile phone processing capacity, but this solution is only applicable to high-end mobile phones, and the versatility is poor, and this solution will improve the mobile phone-based The cost of virtual reality equipment
