Problems solved by technology

The prediction effect based on user habits is poor, mainly because the user's head movement is strongly related to the content of the movie, that is, the user will move according to different movie plots.
Whether it is a traditional machine learning method or a deep learning method, the method based on video content has a very high computational complexity, especially the method based on deep learning has a higher computational complexity, which is difficult for this computationally intensive prediction method. Meet real-time requirements, and its power consumption is also very large

Embodiment Construction

[0028] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0029] The term "computer equipment" in this context, also referred to as "computer", refers to an intelligent electronic device that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions, which may include a processor and The memory is realized by the processor...

Abstract

The invention aims to provide a method and device for predicting a head posture. The method comprises the steps: decoding an audio, and obtaining decoded audio data; analyzing the decoded audio data,determining the sound source position at the next moment, and predicting the head posture of a user at the next moment according to the sound source position at the next moment. The method has the characteristics of small calculation amount, low power consumption and the like, is suitable for being applied to a real-time system, and is also in line with human behavioral habits on the basis of sound prediction.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a technique for predicting head posture. Background technique [0002] In the existing VR (Virtual Reality, virtual reality) panoramic video, only the video content in the FOV (field of view) will be presented in front of the user's eyes when watching, and the video content of other parts is actually invalid. Therefore, many VR panoramic video solutions now use an asymmetric encoding method, that is, only the part of the video that the user sees is of higher definition, and the part that cannot be seen is of lower definition. In order to reduce the delay, it is often necessary to predict the user's head movement position, and pre-download high-definition content within the FOV range for decoding and display. [0003] Existing solutions for predicting head poses usually include traditional machine learning methods or deep learning methods based on user habits or v...
