Abstract: A computer-implemented method is provided for use in location correction of virtual objects in a virtual model of a real-world scene. Location of an object consists of both position and orientation of the virtual object. The method includes generating the virtual model, including a virtual object, and acquiring at least one digital image of a real-world object within the real-world scene, wherein the real-world object corresponds to the virtual object. The method also includes calculating an image-based positional difference between at least one predefined point on the virtual object and at least one corresponding point on the real-world object, adjusting the position and/or the orientation of the virtual object based on this image positional difference, and adjusting the virtual model with respect to the corrected location of the virtual object.

Abstract translation: 提供了一种计算机实现的方法，用于在真实世界场景的虚拟模型中的虚拟对象的位置校正。 对象的位置由虚拟对象的位置和方向组成。 该方法包括生成虚拟模型，包括虚拟对象，以及获取真实世界场景内的真实世界对象的至少一个数字图像，其中真实世界对象对应于虚拟对象。 该方法还包括计算虚拟对象上的至少一个预定义点与真实世界对象上的至少一个对应点之间的基于图像的位置差异，基于该图像来调整虚拟对象的位置和/或取向 位置差异，并且相对于虚拟对象的校正位置来调整虚拟模型。
