Abstract
A distance detecting apparatus can not only measure the distance to a target preceding vehicle but also detect obstacles such as an intervening vehicle, other vehicles running around or adjacent the target vehicle without any movement of the apparatus itself. The apparatus includes a window setting device 13 for setting a plurality of distance-measuring windows 21 through 25 on a screen 20 on the basis of one of two image signals generated by a pair of video cameras 5, 6, a switch 14 for setting an image-following window 26 enclosing the preceding vehicle to be followed, and a CPU 12 for measuring the distance to an object in each distance-measuring window as well as the distance to an object in the image-following window.
