Title
(EN) METHOD FOR PREDICTING A MOTION OF AN OBJECT, METHOD FOR CALIBRATING A MOTION MODEL, METHOD FOR DERIVING A PREDEFINED QUANTITY AND METHOD FOR GENERATING A VIRTUAL REALITY VIEW
(ZH) 预测对象运动的方法、校准运动模型的方法、获得预定义量的方法和生成虚拟现实视图的方法
Abstract
(EN) A method for predicting a motion of an object is provided. The method includes determining a position of the object based on first time-series data of a position sensor mounted to the object and determining an orientation of the object based on second time-series data of at least one inertial sensor mounted to the object. Further, the method includes extrapolating a motion trajectory of the objectbased on a motion model using the position of the object and the orientation of the object, wherein the motion model uses a first weighting factor for the position of the object and a second weighting factor for the orientation of the object. Still further aspects of the present disclosure relate to determining ground truth moments in sensor streams and optimizing virtual reality views for a user.
(ZH) 提供了一种用于预测对象的运动的方法。所述方法包括以下步骤:基于被安装到所述对象的位置传感器的第一时间序列数据来确定所述对象的位置,以及基于被安装到所述对象的至少一个惯性传感器的第二时间序列数据来确定所述对象的取向。此外,所述方法包括以下步骤:使用所述对象的所述位置以及所述对象的所述取向来基于运动模型外推所述对象的运动轨迹,其中,所述运动模型将第一加权因子用于所述对象的所述位置,并且将第二加权因子用于所述对象的所述取向。本公开的又一些另外的方面涉及在传感器流中确定地面实况瞬间并为用户优化虚拟现实视图。
