Abstract
This object detection device for the area around a vehicle is provided with an imaging device and an image processing device. The image processing device is configured from a detection area setting unit, three area processing units, and an integration processing unit. The detection area setting unit sets a trio of small, medium, and large detection areas within a one-frame image captured by the imaging device. Detection processing for the presence of objects within the trio of small, medium, and large detection areas is carried out for each detection area simultaneously and in parallel by the three area processing units using pattern matching. The integration processing unit integrates the plurality of detection results resulting from detection processing by the plurality of area processing units and outputs the result. As a result, the present invention makes it possible to reduce the amount of time required for detection processing.
