Vehicle surroundings monitoring apparatus
First Claim
1. A vehicle surroundings monitoring apparatus having a stereoscopic image detecting unit for detecting a stereoscopic image around a self vehicle, an image processor for processing said image into a distance image and a recognition computer for recognizing objects based on said distance image, comprising:
- classifying means for classifying positional data representing a side wall of a particular one of said objects arranged along a boundary of a road on which said self vehicle is running and positional data of other ones of said objects; and
wall surface detecting means for detecting an outline of said side wall by performing a pattern matching of a side wall surface pattern to said positional data of said side wall, said side wall surface pattern being suitable for said particular object.

Abstract
Distance image outputted from an image processor is read by a recognition/judgment computer, in which the distance image is divided into strips having a specified interval and a histogram is prepared for each strip. Based on the histogram, the position of solid objects and the distance thereto are obtained and these positional data of the solid objects are classified into groups of solid object and groups of side wall. Further, the position of a wall surface forming a boundary of a road is detected from the data of the groups of side wall. On the other hand, assuming a wall surface model composed of a series of nodes, respective nodes are determined and corrected by the data of side wall. Thus obtained nodes form a successive wall surface along a curved road.
