Abstract
This invention relates to a ranging apparatus capable of ranging simultaneously to a three dimensional scene. An illumination means () illuminates a scene with a two dimensional array of spots (). A detector () is located near to the illumination means () and arranged to look toward the scene. A processor () responds to the output from the detector () and, from the location of a spot in the image of the scene, determines the range to that spot. A variety of techniques are used to resolve ambiguity in determining which projected spot is being considered.
