A device may receive, from an imaging device, a two-dimensional image of a patient being operated on by a user, where the two-dimensional image captures a portion of the patient, and where the portion of the patient is provided between a focal point of an imaging source of the imaging device and a detector plane of the imaging device. The device may translate the two-dimensional image along a frustum of the imaging source, and may generate one or more images in a three-dimensional space based on translating the two-dimensional image along the frustum of the imaging source. The device may provide the one or more images in the three-dimensional space to an augmented reality device associated with the user.

A method for aligning a real-world object with a virtual object includes capturing images, video, or both of the real-world object from a first viewpoint and from a second viewpoint. The first and second viewpoints are different. The method also includes simultaneously superimposing the virtual object at least partially over the real-world object from the first viewpoint in a first augmented reality (AR) display and from the second viewpoint in a second AR display based at least in part on the images, video, or both. The method also includes adjusting a position of the real-world object to at least partially align the real-world object with the virtual object from the first viewpoint in the first AR display and from the second viewpoint in the second AR display.
