AI Technical Summary
Technical Problem
In existing technologies, the pose prediction time of VR devices is fixed, resulting in low accuracy of prediction time, which affects the image display effect and may cause black borders or delays.
Method used
By acquiring the current pose of the VR device and the display duration of the current frame image, and combining the current angular velocity and movement speed, the predicted duration is dynamically updated to improve the accuracy of the predicted duration.
Benefits of technology
Dynamically determining the prediction duration improves accuracy, reduces black borders and latency in image display, and enhances the user experience.

Abstract
本申请提供一种位姿的预测时长的确定方法及VR设备用提高预测时长的准确率。包括：每隔指定时长，获取VR设备的当前位姿和当前帧图像的显示时长，其中，当前位姿包括当前位置和当前姿态，且显示时长为从获取图像到显示图像所花费的时长，且当前帧图像的显示时长是基于上一帧图像的显示时长得到的；基于当前姿态和VR设备的上一次获取到的姿态，得到VR设备的当前角速度；基于当前位置和VR设备的上一次获取到的位置，得到VR设备的当前移动速度；利用当前移动速度、当前角速度和当前帧图像的显示时长，得到目标增益时长，其中，目标增益时长为需要对预设的初始预测时长增加的时长；利用目标增益时长更新初始预测时长，得到目标预测时长。
