Abstract
In a road image analyzing apparatus capable of obviously and rapidly distinguishing a road marking from a guardrail and capable of obtaining precise position information, a pre-processing unit defines sub-areas to main image data obtained by an image pickup unit, and an edge extracting unit extracts an edge component in each of the sub-areas. A linear line extracting unit analyzes the extracted edge component to extract a linear component, and a linear component analyzing unit extracts a continuous component from the linear component by using the linear component. A matching process unit performs a matching process between a vertex of the continuous component and auxiliary image data to obtain three-dimensional position information of each continuous component. An identifying unit identifies whether the continuous component is a road marking or a guardrail on the basis of height information of each continuous component included in the three-dimensional position information.
