  • Publication number: 20150338203
    Abstract: A measurement system includes an irradiator, an image capturer, and an arithmetic processor. The irradiator irradiates a first irradiation line with a laser beam at a first irradiation angle, and irradiates second irradiation lines with the laser beam respectively at second irradiation angles. The second irradiation lines intersect the first irradiation line. The image capturer acquires a two-dimensional image of an area including the first irradiation line and the second irradiation lines. The arithmetic processor calculates the second irradiation angles based on the first irradiation angle, based on a first position, in the two-dimensional image, of a first point on the first irradiation line, and based on second positions, in the two-dimensional image, of second points of the second irradiation lines, and calculates three-dimensional coordinates of the second points based on the second irradiation angles and the second positions.

  • Patent number: 8929642
    Abstract: A three-dimensional scanner according to one aspect of the embodiments includes an irradiation unit, an imaging unit, a position detecting unit, and a scanning-region determining unit. The irradiation unit emits a slit-shaped light beam while changing an irradiation position with respect to a measuring object. The imaging unit sequentially captures images of the measuring object irradiated with the light beam. The position detecting unit detects a position of the light beam in an image captured by the imaging unit by scanning the image. The scanning-region determining unit determines a scanning region in an image as a scanning target by the position detecting unit based on a position of the light beam in an image captured by the imaging unit before the image as a scanning target.

  • Publication number: 20140288710
    Abstract: A robot system includes: a robot arm; a camera; a calibration jig with a marker that allows image recognition; and a calibration apparatus configured to derive a correlation between camera coordinates being coordinates in a photographed image and robot coordinates using the robot arm as a reference. The robot arm is configured to have a posture corresponding to a relative position of the camera with respect to the marker. The calibration apparatus sets a plurality of photographing positions by changing the relative position, acquires the camera coordinates of the marker in the plurality of photographing positions and information of the posture of the robot arm, and derives the correlation.

  • Publication number: 20140277694
    Abstract: A robot system includes a robot. The robot includes a holder to hold a first workpiece from among workpieces stored in a stocker. A sensor performs shape recognition of the workpieces stored in the stocker and detects a holding state of the first workpiece held by the robot. A controller controls the sensor to perform the shape recognition of the workpieces stored in the stocker, controls the robot to hold the first workpiece based on the shape recognition and transfer the first workpiece to a particular position in a sensor area of the sensor, controls the sensor to detect the holding state of the first workpiece held by the robot, and controls the robot to place the first workpiece at a predetermined position or in a predetermined posture based on the detected holding state.

  • Publication number: 20140104621
    Abstract: A three-dimensional shape measuring apparatus according to the embodiment includes an irradiating unit, an imaging unit, a position detector, a changing unit. The irradiating unit applies a slit light beam while changing an irradiation position in an area under measurement. The imaging unit images reflected light of the light beam. The position detector scans an image taken by the imaging unit to detect a position of the light beam on the image. The changing unit changes a position of an imaging area of the imaging unit in accordance with the irradiation position of the light beam.
