ROAD OBSERVATION APPARATUS AND METHOD FOR OBSERVING ROAD

A road observation apparatus and a method for observing a road capable of accurately recognizing imaging targets are provided. A road observation apparatus 5 includes a visible range setting section 531 that sets a visible range, which is a range within which an imaging target is recognizable, on the basis of whether a marker is recognizable and a recognition determination section 532 that, if a distant imaging target, which is the imaging target located at a position beyond the set visible range, is recognized, initiates resetting of the visible range and that, if the reset visible range does not exceed the position of the distant imaging target, determines that the recognition of the distant imaging target is incorrect.
