  • Publication number: 20250095369
    Abstract: A controller includes: a first detector that detects a target Wt from an image P including objects W, by using a detection model trained by machine learning; a setter that sets, as a search area A, an area that includes the target Wt detected by the first detector from the image P and is larger than the target Wt; and a second detector that detects the target Wt by performing a matching process based on the search area A of the image P.

  • Publication number: 20250065505
    Abstract: A controller includes: a label assigner that assigns a label indicating predetermined information to an image object in response to input operation of a user; a generator that generates a group of an image and a label assigned to the image as training data; and a storage that stores a second image on which detection by a detection model was performed and failed for an object, in association with a detection result by a detection model. In the second image, the label assigner assigns the label indicating the predetermined information to a detection failed object in response to input operation of the user and substitutes the label indicating the predetermined information of a detection successful object by the detection result. The generator generates a group of the second image, and the label assigned to the detection failed object and the detection result of the detection successful object as training data.

  • Publication number: 20220292702
    Abstract: An image processor includes memory configured to store the shape of an object, extracting circuitry configured to extract a second image of a target range from a first image of the object, distance detecting circuitry configured to process the second image to detect distances from at least three parts projected within the target range to the camera, plane estimating circuitry configured to estimate a plane projected within the target range using the distances based on the at least three parts, angle detecting circuitry configured to detect an angle of the plane with respect to an optical axis of the camera, contour estimating circuitry configured to estimate, based on the shape of the object and the angle of the plane, a contour of the object projected on the first image, and identifying circuitry configured to identify the object on the first image based on the contour.

  • Publication number: 20210198090
    Abstract: A traveling robot includes: a traveling body including a truck and a drive unit, the truck including front and rear wheels and a floor frame, the drive unit being configured to rotate the wheels; a support mechanism configured to raise or lower a holding tool configured to support a mounting plate; and a picking robot configured to load a cargo onto the mounting plate or unload the cargo from the mounting plate. The drive unit is mounted on the floor frame, and the floor frame includes a projecting portion projecting forward from a portion on which the drive unit is mounted. The support mechanism is attached to a front end portion of the projecting portion. The picking robot is provided at the projecting portion, is arranged between the support mechanism and the drive unit in a front-rear direction, and is arranged on or behind an imaginary vertical line passing through a front axle.

  • Patent number: 10751871
    Abstract: The robot includes a first arm having a first hand part provided to a tip end thereof, and at least one joint shaft provided between a pedestal and the first hand part, a first acting part configured to contact a given table-like body on which a plurality of workpieces are able to be placed, while the first acting part is provided to the first hand part, a controller, an imaging unit configured to two-dimensionally image a placement surface of the workpieces in the table-like body in a perpendicular direction to the placement surface, and a recognition part configured to recognize a position of the workpiece by performing a two-dimensional pattern matching based on an image two-dimensionally captured by the imaging unit. The controller vibrates the table-like body by controlling the first arm so that the first acting part acts on the table-like body.
