    Abstract: A sensing data correction system corrects sensing data acquired from a glove-type wearable sensor in which a film-like pressure sensor is incorporated into a fingertip, and includes a data correction unit for correcting the sensing data. Three coordinate axis directions in a three-dimensional orthogonal coordinate system are assumed to be a vertical direction, a longitudinal direction of the pressure sensor, and a width direction of the pressure sensor, and the pressure sensor is obtained by laminating one flexible printed circuit, one sheet-like pressure sensitive element, and one protective film in the vertical direction. An upper surface of the flexible printed circuit and a lower surface of the pressure sensitive element are bonded and fixed to each other, and an upper surface of the pressure sensitive element and a lower surface of the protective film are bonded and fixed to each other. The data correction unit executes sensing data correction processing.

  • Patent number: 11562567
    Abstract: To accurately recognize observed objects. An observed-object recognition system includes an observation region estimation portion, an existence region estimation portion, and an object recognition portion. The observation region estimation portion estimates an observation region that is relatively highly likely to be an observation point in at least one first-person image in a first-person video (a video based on the first-person perspective). Based on the observation region, the existence region estimation portion estimates an existence region that belongs to the first-person image and causes an observed object to exist. The object recognition portion recognizes an object in the estimated existence region of the first-person image.
