Title
(EN) Method for setting viewing direction in representation of virtual environment
(ZH) 用于调节虚拟环境的呈现中的视向的方法
Abstract
(EN) Provided is a method for setting a viewing direction in a representation of a virtual environment. The method includes recording a known object in a real environment with a recording device. The method further includes a determination of a rotational offset of the viewing direction in the representation of the virtual environment about a yaw axis of the representation of the virtual environment, based upon the recording of the object, a known position of the recording device in the real environment and a current viewing direction in the representation of the virtual environment. The method further includes a turning of the viewing direction in the representation of the virtual environment by the amount of the rotational offset.
(ZH) 提出了一种用于调节在虚拟环境的呈现中的视向的方法。该方法包括利用摄录装置摄录在真实环境中的已知的物体。该方法还包括基于物体影像、摄录装置在真实环境中的已知位置以及在虚拟环境的呈现中的当前视向来确定在虚拟环境的呈现中的视向绕该虚拟环境的呈现的偏航轴的转动偏差。该方法还包括使在虚拟环境的呈现中的视向转动该转动偏差。
