  • Patent number: 11010901
    Abstract: A captured image acquisition section 50 acquires, from an imaging apparatus 12, data of a polarized image obtained by capturing a target object and stores the data into an image data storage section 52. A normal line distribution acquisition section 362 of a region segmentation section 310 acquires a distribution of normal line vectors of a subject surface using the polarized image. A region decision section 312 evaluates the distribution of normal line vectors with a predetermined criterion indicating stability such as a dispersion and determines a region in which the stability is high as a region of a figure of a subject to segment the image. An output data generation section 56 carries out various processes using a result of the segmentation to generate output data.

    Abstract: Data of a captured image including a polarized image is acquired (S10), and space information relating to a position and a posture of a subject in a real space and the position and the posture on an imaging plane is acquired using the captured image data (S12). Next, a polarization degree distribution is acquired from a polarized image of a plurality of orientations (S14), and a position of a light source is acquired by specifying an image of a true light source by threshold value determination of the polarization degree (S16). A reflection characteristic is acquired by applying a rendering equation under assumption that luminance of the captured image is already known (S18), and a material suitable therewith is specified as a material of the subject (S20). Processing according to the material is performed to generate output data and output the data (S22).

  • Patent number: 10469829
    Abstract: An information processor acquires a stereo image from an imaging device. A detection plane definition portion defines a detection plane in a three-dimensional space of a camera coordinate system of a first camera. A feature quantity calculation portion generates feature point image of left and right images. A parallax correction area derivation portion derives an area as a parallax correction area, which is obtained by moving, to a left, an area of the right image identical to the detection area of the left image. A matching portion performs matching for the feature point images of each area, thus deriving a highly rated feature point. A position information output portion generates information to be used by an output information generation section based on the matching result.
