Abstract: In an object detection apparatus and an object detection method, as first and second images, captured images of an area ahead of a vehicle in a vehicle advancing direction are acquired from first and second imaging units provided in the vehicle. Based on the first and second images, whether or not an object is present in a blind spot ahead of the vehicle in the vehicle advancing direction is determined. When the object is determined to be present in the blind spot, the first and second images are held in time series. As first and second image differences, differences in a feature quantity between a previous image and a current image in the first and second images are acquired. Based on the first and second image differences, whether or not the object is approaching the area ahead of the vehicle is determined.

Abstract: A driving area recognition device has an image acquiring section for acquiring image data transmitted from an in-vehicle monocular camera and an extraction section for extracting, from the acquired image data, edge points in boundary parts arranged at both the right side and the left side of a driving area of a vehicle. The device further has a setting section for setting plural provisional areas as candidates of the driving area so that at least a part of each of the plural provisional areas is overlapped together, a calculation section for calculating the number of edge points in each of the plural provisional areas, and a recognition section for recognizing the driving area based on the plural provisional areas and the number of edge points in each of the plural provisional areas.

Abstract: In a travel road shape recognition apparatus, a first travel road shape, which approximates a shape of a road boundary, is calculated based on feature points indicating the travel road boundary in a captured image. A worsening position, which is a position on the calculated first travel road shape at which a degree of coincidence with the feature points worsens, is detected over an area from near to far from an own vehicle. A second travel road shape, which approximates a shape of the road boundary in an area farther from the own vehicle, beyond the worsening position, is calculated. The road boundary in the area nearer to the own vehicle, up to the worsening position, is recognized from the first travel road shape. The road boundary in the area farther from the own vehicle, beyond the worsening position, is recognized from the second travel road shape.
