  • Patent number: 10244238
    Abstract: A tile image sequence obtained by dividing a frame into a predetermined size is further divided into another predetermined size on an image plane to generate a voxel (for example, a voxel. If a redundancy in a space direction or a time direction exists, then data is reduced in the direction, and sequences in the time direction are deployed on a two-dimensional plane. Voxel images are placed on an image plane of a predetermined size to generate one integrated image. In a grouping pattern which exhibits a minimum quantization error, pixels are collectively placed in the region of each voxel image for each group (integrated image). The integrated image after the re-placement is compressed in accordance with a predetermined compression method to generate a compressed image and reference information for determining the position of a needed pixel.

  • Patent number: 10210629
    Abstract: A detection area is set in a three-dimensional space in which a subject exists. When an actual hand enters the detection area, coordinate points (white and black dots) represented by pixels making up a silhouette of the hand in a depth image enter the detection area. In the detection area, a reference vector is set that shows the direction which the hand should face relative to the shoulder as a reference point. Then, an inner product between two vectors, a vector from the reference point to each of coordinate points and the reference vector, is calculated, followed by comparison between the inner products. Positions of coordinate points whose inner products are ranked high are acquired as the position of tips of the hand.

  • Publication number: 20180272231
    Abstract: A first estimating unit estimates at least one of a position and an attitude of a predetermined object on the basis of an image of a periphery of the object, the image being obtained from an imaging device, and generates an estimation result not including an accumulated error. A second estimating unit estimates at least one of the position and the attitude of the object on the basis of the image, and generates an estimation result including an accumulated error. A correcting unit compares the estimation result of the first estimating unit and the estimation result of the second estimating unit with each other, and corrects, on the basis of a result of the comparison, a subsequent estimation result of the second estimating unit, the subsequent estimation result being subsequent to the estimation result of the second estimating unit which estimation result is used for the comparison.

  • Publication number: 20180189975
    Abstract: An image acquisition block of an information processing apparatus acquires stereo images taken by a first camera and a second camera that make up an imaging apparatus. An input information acquisition block accepts a user manipulation. A first positional information acquisition block of a positional information generation block identifies an approximate position of an object to be imaged through predetermined means. A second positional information acquisition block determines an estimated distance range of a target on the basis of the identified approximate position of the object to be imaged, detects corresponding points by executing block matching on stereo images thorough only a search range corresponding to the determined estimated distance range, and obtains a position of the target with high resolution and accuracy. An output information generation block generates output data on the basis of the position of that target and outputs the generated output data.

  • Patent number: 9693072
    Abstract: A frame sequence of moving picture data is divided into a tile image sequence, and the color space of the tile image sequence is converted to generate a YCbCr image sequence. Each frame is reduced to ½ time in the vertical and horizontal directions, and a compression process is carried out to generate compression data of a reference image. The compression data of the reference image is decoded and decompressed similarly as upon image display to restore a YCbCr image as the reference image, and a difference image sequence is generated from the reference image and the original YCbCr image. Then, compression data of a difference image is generated, and compression data obtained by connecting the compression data of the reference image and the compression data of the difference image is generated for every four frames of a tile image.
