  8. Stereo vision Left viewpoint Right viewpoint

  9. The Correlation Problem

  10. Correlation algorithms • Sum of Absolute Differences • One of the simplest methods of block searching in images • Assuming normalized images:

  11. Disparity Roof Right viewpoint Left viewpoint Tree branch

  12. Calculating Distance to Objects • Distance to an object is inversely proportional to the disparity of that object Roof (farther away) Right viewpoint Left viewpoint Tree branch (closer)

  13. Applications Mars Curiosity Rover Spirit & Opportunity
