Abstract
In one implementation, a method of performing perspective correction is performed at a head-mounted device including one or more processors, non-transitory memory, an image sensor, and a display. The method includes capturing, using the image sensor, a plurality of images of a scene from a respective plurality of perspectives. The method includes capturing, using the image sensor, a current image of the scene from a current perspective. The method includes obtaining a depth map of the current image of the scene. The method include transforming, using the one or more processors, the current image of the scene based on the depth map, a difference between the current perspective of the image sensor and a current perspective of a user, and at least one of the plurality of images of the scene from the respective plurality of perspectives. The method includes displaying, on the display, the transformed image.
