Abstract
An image processing accuracy estimation unit estimates an image processing accuracy by calculating a size of an object by which the accuracy of measurement of the distance of the object photographed by an on-vehicle camera becomes a permissible value or less. An image post-processing area determination unit determines, in accordance with the estimated image processing accuracy, a partial area inside a detection area of the object as an image post-processing area for which an image post-processing is carried out and lattices the determined image post-processing area to cells. An image processing unit processes the image photographed by the on-vehicle camera to detect a candidate for object and calculates a three-dimensional position of the detected object candidate. An image post-processing unit calculates, in each the individual cell inside the determined area the probability as to whether the detected object is present and determines the presence/absence of the object.
