  • Patent number: 11860602
    Abstract: A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a user interface with a simulation portion (e.g., including a 3D view of a workpiece) and an editing user interface portion (e.g., including an editable plan representation of a current workpiece feature inspection plan). Transparency operations are performed including automatically identifying as a target feature a workpiece feature in the 3D view that corresponds to a workpiece feature or inspection operation representation in the editable plan representation that is indicated by a current feature-directed operation (e.g., a selection operation for selecting a workpiece feature or inspection operation in the editable plan representation). An occluding workpiece feature that would otherwise be occluding at least a portion of the target feature in the 3D view is then automatically rendered as at least partially transparent in the 3D view.

  • Patent number: 10817716
    Abstract: Embodiments provide a process to identify one or more areas containing a hand or hands of one or more subjects in an image. The detection process can start with coarsely locating one or more segments in the image that contain portions of the hand(s) of the subject(s) in the image using a coarse CNN. The detection process can then combine these segments to obtain the one or more areas capturing the hand(s) of the subject(s) in the image. The combined area(s) can then be fed to a grid-based deep neural network finely detect area(s) in the image that contain only the hand(s) of the subject(s) captured.

    Abstract: The present invention relates to an image measurement apparatus images an object to be measured, and measures dimensions and shape of the object to be measured based on an image of the object to be measured displayed on the touch-sensitive panel display. The apparatus comprising: an controller that identifies a command corresponding to a gesture contact-input with respect to the touch-sensitive panel display from a signal output from the touch-sensitive panel display in response to the gesture, and executes the command with respect to a part in the image measurement apparatus, the part being the target of the execution of such command. The gesture is a gesture performed in the state in which the simultaneous touch is made at two or more points.

  • Patent number: 10254113
    Abstract: A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a computer aided design (CAD) file processing portion, an inspection motion path generation portion and a user interface. The user interface includes a workpiece inspection program simulation portion and auxiliary collision avoidance volume creation elements. The workpiece inspection program simulation portion displays a 3D view and the auxiliary collision avoidance volume creation elements are operable to create or define auxiliary collision avoidance volumes that are displayed in the 3D view. In various implementations, rather than requiring a user to model a physical object (e.g., as part of a workpiece or CMM) in a CAD file, the user may instead create and position an auxiliary collision avoidance volume at a location where the physical object is expected to be, so as to prevent collisions that could occur with the physical object.

  • Patent number: 9976852
    Abstract: A system includes an environment for programming workpiece inspection operations for a coordinate measurement machine (CMM). The environment includes a user interface comprising a program simulation portion configured to display a 3D view of the workpiece and/or representations of inspection operations to be performed on the workpiece. The user interface further includes auxiliary collision avoidance volume (CAV) creation elements that create CAV's that are represented in the 3D view. The 3D CAVs and/or their representations have integrated graphical modification properties which are controllable in the user interface. The modification properties are activated by selection of a face of the CAV representation, without the explicit activation of a separate modification control element mode or tool. This results in a simplified and intuitive user interface. Users perform a constrained set graphical modifications in the 3D view using an input device, to modify a CAV.

  • Patent number: 9933256
    Abstract: A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine (CMM). The system includes a computer-aided design (CAD) file processing portion and a user interface which includes an editing user interface portion and an execution time indicator. The CAD file processing portion analyzes an input CAD file to automatically determine workpiece features. The editing user interface portion includes an editable plan representation including an editable set of the workpiece features to be inspected. The execution time indicator is indicative of an estimated inspection program execution time for operating the CMM to execute a corresponding workpiece inspection program. The execution time indicator is automatically updated in response to a utilization of one of a first set of operations to modify the current workpiece feature inspection plan, so as to automatically indicate the estimated effect of the modification on the inspection program execution time.

  • Patent number: 9646425
    Abstract: A system is provided for programming workpiece feature inspection operations for a coordinate measuring machine. The system includes a computer-aided design (CAD) file processing portion and a user interface comprising a 3D view, and editable plan representation. Both the 3D view and the editable plan representation are configure to be automatically responsive to operations in a first set of editing operations, regardless of whether the operations are performed in the 3D view or the editable plan representation of the user interface. The first set of editing operations may comprise deleting (or adding) at least one workpiece feature in the 3D view or the editable plan representation of the user interface, for example. Various other portions of the system (e.g. other user interface windows) may also be automatically responsive to the first set of editing operations, regardless of where the editing operations are performed in the user interface.

  • Patent number: 9639083
    Abstract: A system and method are provided for programming workpiece feature inspection operations for a coordinate measuring machine. An editing environment is operated to display a 3-dimensional workpiece representation comprising a first surface feature of a workpiece. A first feature surface sampling pattern is created having at least one pattern parameter adjusted to correspond to a first surface feature of the workpiece. A corresponding representation of the sampling pattern includes operative sampling pattern locations located proximate to the first surface feature. User operations in the GUI further adjust pattern parameters of the sampling pattern. The further adjustment of the pattern parameters simultaneously affects a plurality of the sampling pattern locations.
