  • Patent number: 10401844
    Abstract: A structure allows more efficient simulation using preliminary obtained image data for a target such as a workpiece. A simulator includes a creating unit that virtually creates a simulation target system in a three-dimensional virtual space, a measurement unit that performs image measurement of preliminary obtained image data using a visual sensor and outputs a measurement result, a reception unit that receives a setting of an imaging area defined for the visual sensor in a manner associated with the created system, a calculation unit that calculates a transform parameter based on a relative positional relationship between the created system and the set imaging area, and an execution unit that receives an input of a result obtained by transforming the measurement result generated by the measurement unit using the transform parameter, and executes a control operation in accordance with a control program associated with the system.

  • Patent number: 9896038
    Abstract: A work vehicle which can provide more accommodation space for articles on a vehicular body frame is provided. A rear cab mount on which a cab of a hydraulic excavator is mounted is mounted on a revolving frame and forms a hollow rear under-mount space. An opening portion is formed at a position corresponding to a side of the rear under-mount space in an exterior cover which laterally covers the revolving frame. A rear door body can open and close the opening portion. The rear door body opens the rear under-mount space to an external space with the opening portion being opened.

  • Patent number: 9741108
    Abstract: An image processing apparatus, connected to an imaging part to capture an image of workpieces conveyed on a conveyer, includes an interface that receives a signal indicating a travel distance of the conveyer, an interface that communicates with a control device for controlling a moving machine disposed downstream of an imaging area of a imaging part, a positional information acquisition unit that processes the image captured by the imaging part and thereby acquiring positional information of a pre-registered workpiece in the image, a travel distance obtaining unit that obtains the travel distance of the conveyer synchronized with the control device, an initiating unit that initiates the capturing by the imaging part in response to an imaging command, and a transmission unit that transmits, to the control device, the positional information and the travel distance upon the capturing of the image used to acquire the positional information.

  • Patent number: 9424646
    Abstract: A control system executes a first control operation, and then executes a second control operation. In the first control operation, the image processing section obtains the image data and specifies a position of a characteristic part. The control section determines a control instruction for accelerating an object to a predetermined first speed based on the specified position of the characteristic part and then decelerating the object to a predetermined second speed lower than the first speed, to move the object to an intermediate target position away from the final target position by a predetermined margin distance. In the second control operation, the image processing section obtains the image data during movement of the moving mechanism and specifies the position of the characteristic part, and the control section determines a control instruction for positioning the object to the final target position based on the specified position of the characteristic part.
