Claim 12:
13. A device, comprising:
a camera;
a processor; and
a memory, the processor configured to execute instructions stored in the memory causing the processor to:
receive a two-dimensional (2-D) still image of a scene recorded by the camera;
identify an object depicted in the 2-D still image as having known dimensions;
segment the 2-D still image into a segmented object image portion containing the object having the known dimensions including a known height corresponding to an image height in the 2-D still image;
calculate a depth from the camera of the segmented object image portion containing the object using only the known height of the object, an intrinsic parameter of the camera, and the image height of the object;
prepare a depth map corresponding to the 2-D still image using the depth from the camera of the segmented object image portion containing the object; and
overlay augmented reality content over a display of the 2-D still image of the scene using the depth map to position the augmented reality content over the 2-D still image, wherein using the depth map to position the augmented reality content over the 2-D still image includes using the object present in the scene as a fiducial marker to determine a pose of the camera.
