  • Patent number: 11967101
    Abstract: The present invention provides a motion capture with a high accuracy which can replace an optical motion capture technology, without attaching optical markers and sensors to a subject. A subject with an articulated structure has a plurality of feature points in the body of the subject including a plurality of joints wherein a distance between adjacent feature points is obtained as a constant. A spatial distribution of a likelihood of a position of each feature point is obtained based on a single input image or a plurality of input images taken at the same time. One or a plurality of position candidates corresponding to each feature point are obtained based on the spatial distribution of the likelihood of the position of each feature point. Each join angle is obtained by performing an optimization calculation based on inverse kinematics using the candidates and the articulated structure.

    Abstract: An antenna includes a conductive patch. The patch includes, in a plan view, a first power feed-side edge and a first non-power feed-side edge positioned on opposite sides in a first direction in one-to-one relation, and a second power feed-side edge and a second non-power feed-side edge positioned on opposite sides in a second direction intersecting the first direction in one-to-one relation. The patch includes, in the plan view, a first power feed point positioned on a side nearer to the first power feed-side edge and a second power feed point positioned on a side nearer to the second power feed-side edge. In the plan view, at least a portion of the first power feed-side edge expands outward and forms a protrusion. A width of the protrusion in the second direction gradually decreases toward a top of the protrusion. The first power feed point is positioned nearer to the top of the protrusion than a middle of a hill slope of the protrusion in the first direction.
