    • Methods, systems, and apparatus, including computer program products, for aligning images are disclosed. In one aspect, a method includes receiving an inaccurate three dimensional (3D) position of a physical camera, where the physical camera captured a photographic image; basing an initial 3D position of a virtual camera in a 3D virtual environment on the inaccurate 3D position of the physical camera; correlating one or more markers in the photographic image with one or more markers in the 3D virtual environment that appear in the virtual camera's field of view; and adjusting the initial 3D position of the virtual camera in the 3D virtual environment based on a disparity between the one or more markers' 3D positions in the photographic image as compared to the one or more markers' 3D positions in the virtual camera's field of view.
    • 公开了用于对准图像的方法,系统和装置,包括计算机程序产品。 在一个方面,一种方法包括接收物理相机的不准确的三维(3D)位置,其中物理照相机拍摄摄影图像; 将3D虚拟环境中的虚拟相机的初始3D位置基于物理相机的不准确的3D位置; 将摄影图像中的一个或多个标记与出现在虚拟相机的视野中的3D虚拟环境中的一个或多个标记相关联; 以及在虚拟相机的视场中与一个或多个标记的3D位置相比,基于摄影图像中的一个或多个标记的3D位置之间的差异来调整3D虚拟环境中的虚拟相机的初始3D位置 。
