Abstract
The current disclosure describes a stereo imaging system that is configured to use Time-of-Flight (“Tof”) techniques to aid in stereoscopic image processing. One process disclosed uses ToF to aid in identifying the same elements (e.g., pixel clusters) in stereo image pairs by narrowing down search areas for matching. Another process uses ToF to aid in identifying the same elements in stereo image pairs where there a small amount texture making it difficult to find a match.
