Abstract
A distance detecting apparatus in which an operator is able to readily and accurately see to which one of a plurality of objects the distance is detected. The apparatus is able to concurrently detect the distances to a plurality of objects which exist within the field of view of the subject vehicle. To this end, the apparatus includes: a pair of first and second image sensors including a pair of optical systems for optically sensing a plurality of objects; a first memory for storing the pictures of the objects sensed by the first image sensor as first image signals; a second memory for storing the pictures of the objects sensed by the second image sensor as second image signals; a window defining device for defining a plurality of windows at specific areas of the first or second image signals; and a calculator for making image signals within the respective windows defined by the window defining device as reference signals. The calculator is operable to make a comparison between those of the first and second image signals which correspond to the reference signals, to individually calculate the distance to each object in each window. Preferably, the first and second image sensors are disposed in a vertically spaced apart relation.
