Abstract
Light detection apparatus for determining the location of a body within a predetermined area comprises at least two light detecting devices ( ″), supported on the body and capable of receiving light at points which are spaced about a central axis ( ). The apparatus further includes means for supplying information representative of the level of light detected by each light detecting device ( ″). Information received from the light detection apparatus is compared with information previously received from the light detection apparatus and stored in a memory so as to identify when the light detected by the light detection apparatus is the same or substantially the same as light previously detected by the light detection apparatus. When used on an autonomous vehicle, this can allow the vehicle to determine when it has returned to a similar position in an area. The received light signals can be filtered or processed to derive information representative of different types of light (natural, incandescent) or colours of light.
