Patent Images

1. A method implemented by one or more computing devices, the method comprising:

  • determining a search range for calculating stereo correspondence for images of an image scene based at least in part on;

    a depth map, generated through the use of a depth sensor, of the image scene;

    examining confidence values, generated by the depth sensor, included in the depth map; and

    selecting between a search range calculated based at least in part on uniqueness of pixels in relation to each other and a search range calculated at least in part based on the confidence values generated by the depth sensor; and

    calculating stereo correspondence of image data of stereoscopic images of the image scene, the calculating performed based at least in part using the determined search range.
