Abstract
A moving object detection method and apparatus is proposed in which a plurality of heads are installed above a detection line traversing a road, their outputs undergo A/D conversion and binary conversion, and the outputs are then linked along the detection line. A vehicle detection preprocessor performs, on the obtained linked 0/1 existence data, vehicle detection preprocesses of filling-up, noise rejection, width maintaining, Y character profile prevention, delaying, maximum width checking, and so forth, in a predetermined sequence. A vehicle detection processor separates and detects entering vehicles, existing vehicles, corrected/deleted vehicles, and so forth, from the linked 0/1 existence data after vehicle detection preprocessing. False detection of moving objects is reduced.
