Patent Images
1. An apparatus, comprising:
- a camera for taking a first picture of an object from a first location at a first time and for taking a second picture of the object from a second location at a second time;
a motion measurement device coupled to the camera, the motion measurement device to determine changes in angular direction of the camera for the first and second pictures and changes in linear position of the camera between the first and second locations; and
a processing device to determine three dimensional information about the object with relation to the camera, based on the changes in the angular direction and the changes in the linear position.

Abstract
In various embodiments, a camera takes pictures of at least one object from two different camera locations. Measurement devices coupled to the camera measure the change in location and the change in direction of the camera from one location to the other, and derive 3-dimensional information on the object from that information and, in some embodiments, from the images in the pictures.
