Abstract
In accordance with some embodiments, systems, methods and media for determining object motion in three dimensions using speckle images are provided. In some embodiments, a system for three dimensional motion estimation is provided, comprising: a light source; an image sensor; and a hardware processor programmed to: cause the light source to emit light toward the scene; cause the image sensor to capture a first defocused speckle image of the scene at a first time and capture a second defocused speckle image of the scene at a second time; generate a first scaled version of the first defocused image; generate a second scaled version of the first defocused image; compare each of the first defocused image, the first scaled version, and the second scaled version to the second defocused image; and determine axial and lateral motion of the object based on the comparisons.
