    • In a method of determining a position and orientation of a device, the position and orientation is determined based on multiple degrees of freedom and the device is associated with a capturing device for capturing at least one image, the method comprising the steps of: capturing at least one image of at least one real object or part of a real object with the capturing device, and providing a coordinate system in relation to the object, providing an estimation of intrinsic parameters of the capturing device, providing pose data allowing to compute at least one first degree of freedom in the coordinate system having a first confidence degree, and at least one second degree of freedom in the coordinate system having a second confidence degree different from the first confidence degree, calculating an initial pose of the device with respect to the object based on the first and second degrees of freedom having the first and second confidence degree, performing a pose estimation process for determining an estimated position and orientation of the device with respect to the object, and calculating in the pose estimation process an estimation of the degrees of freedom having the second confidence degree based on the initial pose and the at least one image and the estimation of intrinsic parameters of the capturing device, determining a position and orientation of the device with respect to the object based on the estimation of the degrees of freedom calculated in the pose estimation process and the degrees of freedom having the first confidence degree.
    • 在确定设备的位置和方向的方法中,基于多个自由度确定位置和取向,并且该设备与用于捕获至少一个图像的捕获设备相关联,该方法包括以下步骤: 至少一个真实对象或具有捕获设备的真实对象的一部分的至少一个图像,以及提供与对象相关的坐标系,提供对捕捉设备的固有参数的估计,提供允许至少计算的姿态数据 在具有第一置信度的坐标系中的第一自由度和具有与第一置信度不同的第二置信度的坐标系中的至少一个第二自由度,计算装置相对于第一置信度的初始姿态 基于具有第一和第二置信度的第一和第二自由度的对象,执行姿态估计处理 确定所述装置相对于所述物体的估计位置和方向,以及在所述姿态估计处理中基于所述初始姿态和所述至少一个图像以及所述至少一个图像的估计来计算具有所述第二置信度的所述自由度的估计 基于在姿态估计处理中计算的自由度的估计和具有第一置信度的自由度来确定装置相对于对象的位置和方位的参数。
