More Information
Summary:An example apparatus for calibrating depth cameras includes an image receiver to receive an image from a depth camera. The apparatus also includes an object detector to detect a natural object with an expected shape in the image. The apparatus further includes a parameter adjuster to adjust a parameter of the depth camera to reduce a detected difference between the expected shape and a measured characteristic of the natural object.
