  • Publication number: 20260162277
    Abstract: Skeleton information is visualized in response to diverse needs of individual sites. A gait behavior visualization system stores skeleton data, which is time-series data indicating trajectories of a plurality of sites set for a measurement subject in a three-dimensional space for a gait of the measurement subject, period determination data, which is information used for specifying a time corresponding to each of periods of one gait for the skeleton data, and a perspective defined by designating the period, the site, and a displaying method for the trajectory; specifies a time corresponding to the period for the skeleton data by comparing the skeleton data and the period determination data; and generates, based on the skeleton data for the period designated in the perspective, a screen on which the trajectory of the site designated in the perspective is presented according to the displaying method designated in the perspective.

  • Patent number: 12519896
    Abstract: An image reading device (100) includes a lens array (4), a light receiver (6), and at least one light blocking member. The lens array (4) includes first lens bodies arranged in a line in a main scanning direction with predetermined spacing therebetween to converge light from a reading target. The light receiver (6) receives light converged by each first lens body. The at least one light blocking member is disposed between the light receiver (6) and an end of the lens array (4) proximate to the reading target at at least one position corresponding to the predetermined spacing in the main scanning direction. The at least one light blocking member blocks light from the reading target propagating between the first lens bodies, and each of the at least one light blocking member separates optical paths of light converged by ones of the first lens bodies adjacent to each other.

  • Publication number: 20240355479
    Abstract: A measurement apparatus includes: a measurement data acquisition unit configured to acquire measurement data of a target; and a processing unit configured to process the measurement data. The processing unit estimates a skeleton of a living body that is the target based on the measurement data, estimates a measurement condition related to the measurement data using an estimation result of the skeleton, obtains a similarity between the measurement condition and an assumed condition assumed in advance, and selects measurement data related to evaluation of a state of the target based on the similarity. With the configuration and operations,, it is possible to efficiently collect data related to evaluation of a state of a target while considering a restriction of a location where measurement data is acquired, without collecting a large amount of data.
