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.

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.

Inspection program editing environment providing user defined collision avoidance volumes

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.

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 including a workpiece inspection program simulation portion, an editing user interface portion, and a simulation status and control portion. The simulation status and control portion is configured to respond to selection of workpiece features or inspection operation representations (e.g., as selected in the workpiece inspection program simulation portion or editing user interface portion). The simulation status and control portion response to the selection includes altering a simulation status portion (e.g., altering a numerical time representation or a position of a current time indicator) to characterize a state of progress through a current workpiece feature inspection plan corresponding to the portion of the current workpiece feature inspection plan directed to the selected workpiece feature or inspection operation representation.

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.

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.

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. The sampling pattern representation may include various types of operative and inoperative sampling pattern locations, which may be displayed in a manner that distinguishes them from one another, such as by being represented with different colors, shapes or patterns.

A method is provided for controlling a Tracking AutoFocus (TAF) portion of a machine vision inspection system including an imaging portion, a movable workpiece stage, a control portion, and graphical user interface (GUI). The TAF portion automatically adjusts a focus position of the imaging portion to focus at a Z height corresponding to a current surface height of the workpiece. The method includes providing the TAF portion, and providing TAF enable and disable operations, wherein: the TAF disable operations comprise a first set of TAF automatic interrupt operations that are automatically triggered by user-initiated operations that include changing the Z height, and the TAF disable operations may further comprise automatic interrupt operations that are automatically triggered based on at least one respective TAF Z height surface tracking characteristic exceeding a previously set TAF disable limit for that respective TAF Z height surface tracking characteristic.

A method is provided for defining and utilizing an editing initialization block for a part program. The part program comprises a plurality of steps for taking measurements of a part and is displayed in an editing interface. An option is provided in the editing interface for selecting which steps are in an editing initialization block. After the part program has been saved, at a later time when the part program is recalled for editing, the editing initialization block may be run before additional steps are added to the part program. At least some of the data that would have been obtained by one or more of the initial part program steps that are not in the editing initialization block may be based on estimated data that is related to (e.g., modified based on) data determined from running the editing initialization block.

A machine vision system program editing environment includes near real time context generation. Rather than requiring execution of all preceding instructions of a part program in order to generate a realistic context for subsequent edits, surrogate data operations using previously saved data replace execution of certain sets of instructions. The surrogate data may be saved during the actual execution of operations that are recorded in a part program. An edit mode of execution substitutes that data as a surrogate for executing the operations that would otherwise generate that data. Significant time savings may be achieved for context generation, such that editing occurs within an operating context which may be repeatedly refreshed for accuracy in near real time. This supports convenient program modification by relatively unskilled users, using the native user interface of the machine vision system, rather than difficult to use text-based or graphical object-based editing environments.

A method is provided for programming step and repeat operations of a machine vision inspection system. The machine vision inspection system includes an imaging portion, a stage for holding one or more workpieces in a field of view (FOV) of the imaging portion, a control portion, and a graphical user interface (GUI). According to the method, a user operates the machine vision inspection system to define a set of inspection operations to be performed on a first configuration of workpiece features. The user also operates the GUI to display a step and repeat dialog box, in which he defines a first plurality of parameters defining a set of default step and repeat locations for performing the defined set of inspection operations. The user further operates the GUI to define a set of inspection step and repeat locations, which is a subset of the defined set of default step and repeat locations, where the inspection operations are to be actually performed.

A system and method for tool enhancements are provided which allow users to utilize video tools in a controlled manner. The video tools balance a minimal amount of cursor positioning and 'mouse clicks' against a level of video tool 'customization' control desired by a user when applying the video tools. Tool construction methods using multiple mouse clicks are provided as an alternative to using drag-and-draw and one-click tools. Multi-click-plus tools give more specific information and provide a precise way to rapidly create customized tools.

A system and method are provided for a 'multi-region' autofocus video tool-type or mode within a machine vision inspection system. The user may efficiently define multiple regions of interest that are grouped as a 'multi-region' set. The autofocus operations for the multi-region set are defined with a shared set of autofocus parameters. The same set of autofocus images may be used for the autofocus operations of the multi-region set. The user may conveniently also define individual autofocus regions of interest, defined with individual autofocus parameters, within the same field of view. Various user interface features allow a user to conveniently change between the individual autofocus tool-type or mode and the multi-region autofocus tool-type or mode.

A handheld metrology imaging system and method. In one embodiment, the device may comprise an imaging portion, a display portion, a signal processing and control portion, an image capture activation element and a user interface. The user interface may comprise user adjustable video measurement tools configurable relative to an image on the display portion, and video tool adjusting elements. Measurement functions are provided that operate to provide a dimensional measurement result based on the configurations of the video measurement tools. The handheld device can be used to measure not only the normal parts which have traditionally been measured by conventional handheld tools such as a caliper or micrometer, but also very small or flat parts that are difficult to measure with conventional tools.

A method and apparatus for tracing an edge contour of an object in three dimensional space is provided. The method and apparatus is utilized in a computer vision system that is designed to obtain precise dimensional measurements of a scanned object. In order to save focusing time during an automatic tracing measurement, multiple images may be collected and saved for a number of Z heights for a particular position of the XY stage. These saved images can later be used to calculate a focal position for each edge point trial location in the selected XY area rather than requiring a physical Z stage movement. In addition, a Z height extrapolation based on the Z heights of previous edge points can significantly speed up the searching process, particularly for objects where the Z height change of a contour is gradual and predictable.
