INFORMATION PROCESSING DEVICE AND INFORMATION PROCESSING METHOD

摘要

An information processor acquires a stereo image from an imaging device. In a position information generation section 46, a detection plane definition portion 60 defines a detection plane in a three-dimensional space of a camera coordinate system of a first camera and calculates vertex coordinates of a detection area by projecting the detection plane onto a plane of a left image shot by the first camera. A feature quantity calculation portion 62 generates feature point image of left and right images. A parallax correction area derivation portion 64 derives an area as a parallax correction area. The parallax correction area is obtained by moving, to a left, an area of a right image identical to the detection area of the left image by as much as the parallax appropriate to a position of the detection plane in a depth direction. A matching portion 68 performs block matching for the feature point images of each area, thus deriving a highly rated feature point. A position information output portion 70 generates information to be used by an output information generation section 50 based on the matching result and output that information.
