DEPTH MAPPING USING TIME-CODED ILLUMINATION
First Claim
Patent Images
1. A method for depth mapping, comprising:
- illuminating an object with a time-coded pattern;
capturing images of the time-coded pattern on the object using a matrix of detector elements;
decoding the time-coded pattern in the captured images using processing circuitry embedded in each of the detector elements so as to generate respective digital shift values; and
converting the shift values into depth coordinates.

Abstract
A method for depth mapping includes illuminating an object with a time-coded pattern and capturing images of the time-coded pattern on the object using a matrix of detector elements. The time-coded pattern in the captured images is decoded using processing circuitry embedded in each of the detector elements so as to generate respective digital shift values, which are converted into depth coordinates.
