Image recording apparatus and method using light fields to track position and orientation
First Claim
Patent Images
1. An image recording apparatus comprising:
- an image pickup device that acquires images of the surrounding environment, the images being a sequence of frames;
a frame storage that stores the sequence of frames acquired by the image pickup device; and
a processor that determines a position and an orientation of the image pickup device based on the sequence of frames, wherein the frames comprise a plurality of lines and the processor determines the position of the image pickup device by correlating a radiance along at least one of the plurality of lines in a current frame with the radiance along corresponding ones of the plurality of lines of at least one previous'"'"'frame in the sequence of frames.

Abstract
The invention provides a simple method and apparatus for tracking image recording device motion using a light field. The invention locates the image recording device'"'"'s position and orientation in each frame very precisely by checking the radiance seen along lines captured in previous frames. The invention provides an interactive system that provides the operator with feedback, to capture a sequence of frames that sufficiently cover the light field, to provide sufficient data for reconstruction of three-dimensional structures.

15. A method of determining a position and an orientation of an image recording apparatus, comprising:
-
recording a sequence of image frames;
determining the position and the orientation of the image recording apparatus for each frame of the sequence of frames;
providing registration feedback to an image recording device operator in real time;
recording a new image frame;
determining the position and orientation of the image recording apparatus for the new image frame based on the position and orientation of the image recording apparatus for frames in the sequence of image frames. - View Dependent Claims (16, 17, 18, 19, 20, 21)
