Title: Device for measuring distance between vehicles and stereo image pick-up device
Inventor: SUZUKI SACHIHIRO
IPC: G06T7/00
Filed: 1993-05-25
Abstract: PURPOSE:To accurately measure the distance to a preceding vehicle by using a horizontal edge located inside a region within each vehicle image picked up by two video cameras and then performing corresponding retrieval utilizing only the information near a horizontal contour. CONSTITUTION:A set of vehicle forward images are picked up by video cameras 1 and 2. A vehicle region extraction means 3 cuts a region other than asphalt using brightness information. A horizontal edge extraction means 4 extracts edge constituents with a horizontal angle using a sobel filter. A horizontal contour approximation means 5 obtains a horizontal segment from the horizontal edge constituents using hough exchange. A corresponding retrieval means 6 obtains corresponding horizontal segments (a plurality of sets) from the inside of two images and obtains the amount of deviation (visual difference) where the correlation of the brightness distribution on a scanning line where each horizontal segment exists reaches the maximum. A distance calculation means 7 performs the following calculation to obtain the distance to the preceding vehicle: Distance= (installation spacing of cameras 1 and 2*lens focusing distance)/{Visual differenceXdistance conversion constant (constant for converting obtained distance to actual distance)}.
