Abstract
An inter-vehicle distance measuring device which can automatically set a tracing window for tracing an image of a fore-running vehicle to be measured for distance. A window setting unit sets plural numbers of windows at given locations on one of the images. An estimate member calculates a distance up to objects caught by those windows, detects the symmetry of the image, and estimates presence of a fore-running vehicle and its position on one of images, and the detected distance data as well. A tracing window is automatically set at the position.
