An imaging apparatus comprising: an imaging unit being a stereo camera configured to generate one of distance information and luminance information based on image information captured by the imaging unit; and an information processing apparatus comprising: an object region detecting unit configured to detect an object region based of the distance information and the luminance information; a local region detecting unit configured to, when a divided area obtained by dividing the detected object region meets a predetermined condition for when one of the thickness of an object in the divided area is smaller than a first thickness feature amount, wherein the thickness is defined as the difference between the top and the bottom of the object, and the height of the object from a road surface is greater than a first height feature amount, detect the divided area as a local region, wherein the height of the object from the road surface is defined as a height of the bottom of the object from the road surface; and an object specifying unit configured to specify, as a bar-shaped specification target object, the object region in which the local region is detected to continue in an elongated manner in a lateral direction, characterized by an excluding unit configured to, when objects detected by the object region detecting unit have a front-back positional relationship and are located within a certain distance indicating that a single object is detected in a partially divided manner, exclude at least a first object of the objects located on the front side among the objects having the front-back positional relationship from the specification target object if the first object has a predetermined overlapping rate calculated as (min(right edge of the first object, right edge of another second one of the objects) - max(left edge of the first objects, left edge of the second object) × 100 / width of the first object). an imaging unit being a stereo camera configured to generate one of distance information and luminance information based on image information captured by the imaging unit;
