Abstract
A distance between a running vehicle and an object is determined over an imaged picture with high reliability. Three-dimensional objects or a road shape along with accurate position or dimension are also detected. An object within a set region outside a vehicle is imaged by a stereoscopic optical system to input the imaged picture of the object into a stereoscopic picture processing apparatus. The stereoscopic picture processing apparatus processes the picture imaged by the stereoscopic optical system to calculate a distance distribution over the entire picture. A road/three-dimensional object detecting apparatus calculates three-dimensional positions of respective portions of objects corresponding to information of the distance distribution to detect the shape of the road and a plurality of three-dimensional objects by using information of these three-dimensional positions securely and with high reliability.
