Vehicle-surroundings monitoring apparatus
First Claim
1. A vehicle-surroundings monitoring apparatus which is mounted on a vehicle for monitoring nearby objects lying therearound, said apparatus comprising:
- sensing means including two optical systems for sensing said objects lying around said vehicle from two different points and forming images of said objects on image sensor means;
display means for displaying images of said objects on a screen;
window setting means for setting a plurality of windows on the screen of said display means;
distance detecting means for detecting the distance to each object in each of said windows based on the principles of trigonometry by detecting a deviation between images of each object sensed by said two optical systems through comparison therebetween; and
detecting range .restricting means for restricting a distance detecting range for each window to a predetermined range to thereby select as a nearby vehicle an object to which the distance is within the predetermined range.

Abstract
A vehicle-surroundings monitoring apparatus is free from mistakenly identifying a lane marker on a road surface or a guard rail as a vehicle traveling in the blind spot of a nearby lane. A distance detecting section detects the distance up to a vehicle which is traveling in the blind-spot of a nearby lane and which is captured by a plurality of windows as set on a display screen. A detecting range restricting section restricts a distance detecting range for each window to a predetermined range to thereby select as a nearby vehicle an object to which the distance is within the predetermined range.
