A recognition apparatus is provided which includes an input section that receives image information from a front camera and a rear camera, and a calculation section that performs a forward recognition process that is a recognition process targeting the image information from the front camera received by the input section and a rearward recognition process that is a recognition process targeting the image information from the rear camera received by the input section. The calculation section includes an acquisition section that acquires first information representing whether an own vehicle is in a state of moving forward or a state of moving rearward and second information representing a traveling condition of the own vehicle, and a process selection section that selects processes to be performed as the forward recognition process and the rearward recognition process, based on the first and second information acquired by the acquisition section.

Recognition apparatus

A vehicle detection apparatus detects an object based on an image captured from a vehicle. In the vehicle detection apparatus, a camera is mounted in the vehicle. A search region determining unit determines a region including a road surface in the image to be a search region. A cost minimizing unit divides the search region into two, an upper region and a lower region, by a boundary line, determines corresponding points in a plurality of images captured by the camera at different time points by applying an optical flow model having a fixed magnification factor to the upper region and an optical flow model having a planar constraint condition to the lower region, and determines a boundary line that minimizes cost related to a difference between pixel values of the corresponding points. A vehicle presence determining unit determines presence of a forward vehicle based on the boundary line.
