Structured Light

Categories: Vision


Author(s): R.M. Cameron-Jones

The use of the geometry of the illumination actively emitted into the scene to simplify the task of inferring environmental structure. It is often used for Range Finding. The best known example of structured light is illuminating the scene with a (scanning) light-stripe enabling the direct interpretation of breaks in the sensed line as depth discontinuities in the scene. With knowledge of the geometric position of the light source and the relative position of the sensor system, the scene position of the observed stripe can often be calculated.
