Abstract

This invention provides a system and method for employing GUI-based non-numeric slide buttons and bar meters to setup and monitor operating parameters of a vision system. Graphical representations of operating parameters are displayed in a parameter box on the GUI with moving bars that are shaded, patterned or colored so as to provide a relative level between two extremes on a scale of the given operating parameter. Input of operating parameter settings with respect to the scale is made by moving a setting slider along the scale between the extremes. The position of the slider establishes the user-input setting relative to the scale. In an illustrative embodiment, scales, level bars and setting sliders can also be displayed on the image view itself, adjacent to a given image view feature, which is the subject of the scale.

Claims

1. A method for displaying and controlling vision system operating parameters comprising the steps of:

displaying, on a graphical user interface (GUI) operated by a processor, a plurality of captured images wherein each captured image varies slightly as a result of relative motion within a field of view of a vision system imager;

defining a selected image that is one of the plurality of captured images from a window on the graphical GUI;

applying an automated locator graphic image to a particular location on the selected image in response to user input of clicking on at least a portion of the selected image;

applying one or more automated operating parameters to a desired orientation of the selected image;

defining the automated locator graphic image by at least one user definable operating parameter of the one or more automated operating parameters located in a separate control box displayed on the GUI, the at least one user definable operating parameter being in a non-numeric graphical format that includes a scale having a predetermined area and a user-movable setting graphic having a distinct appearance with respect to the scale; and

setting the user-movable setting graphic of the locator graphic image in response to the user moving the user-movable setting graphic to a desired level of the operating parameter, the user movable setting graphic located with respect to the predetermined area of the scale.

2. The method as set forth in claim 1 wherein the scale comprises a linear bar having a first end point and an opposing second endpoint and the moving region comprises a bar having a leading edge that moves across the scale to define the level of the operating parameter.

3. The method as set forth in claim 2 wherein the user-movable setting graphic comprises a slider graphic located so as to move to setpoints along the linear bar between the first endpoint and the second endpoint.

4. The method as set forth in claim 3 further comprising a non-numeric setting slider that allows a predetermined operating parameter to be set between a first end and a second end of a predetermined operating parameter range.

5. The method as set forth in claim 3 wherein the leading edge defines a level of threshold in the image view at which a predetermined function of the vision system is operating and a boundary defines a desired threshold level at which the predetermined function of the vision system responds.

6. The method as set forth in claim 4 wherein the leading edge defines a level of threshold in the image view at which a predetermined function of the vision system is operating and a boundary defines a desired threshold level at which the predetermined function of the vision system responds.

7. The method as set forth in claim 6 wherein the non-numeric setting slider defines operating levels at which the predetermined function operates.

8. The method as set forth in claim 7 wherein the predetermined function comprises a brightness tool and operating levels comprise a brightness range between two settable brightness range endpoints.

9. The method as set forth in claim 7 wherein the predetermined function comprises a contrast tool and the operating levels comprises a contrast sensitivity that is set within range between zero contrast and maximum contrast.

10. The method as set forth in claim 7 wherein the linear bar is provided in a parameter box at a location in the GUI that is accessed with respect to the predetermined function.

11. The method as set forth in claim 10 further comprising another linear bar having a first end point and an opposing second endpoint and another bar having a leading edge that moves across the scale to define the level of the operating parameter, the linear bar being located on the image view adjacent to a graphical representation on the image view of the predetermined function.

19. The method of claim 1 wherein the defining step is in response to an input, by a user, that selected the image.

20. The method of claim 1 wherein an edge of the user-movable setting graphic defines a level of the operating parameter.

12. A method for displaying and controlling vision system operating parameters comprising the steps of:

displaying, on a graphical user interface (GUI) operated by a processor, a plurality of captured images;

enabling selection of at least one image of the plurality of captured images to define a selected image;

generating an automated locator graphic image that is applied to a particular location on the selected image;

applying one or more automated operating parameters to a desired orientation of the selected image; and

providing at least one user definable operating parameter that defines the automated locator graphic image, the at least one user-definable operating parameter being located in a separate control box displayed on the GUI and displayed in a non-numeric graphical format that includes a scale having a predetermined area and a user-movable setting graphic having a distinct appearance with respect to the scale, wherein a feature of the user-movable setting graphic defines a level of the operating parameter.

13. The method of claim 12 wherein each captured image of the plurality of captured images varies slightly as a result of relative motion within a field of view of a vision system imager.

14. The method of claim 12 wherein the step of applying one or more automated operating parameters is performed in response to a user input.

15. The method of claim 12 wherein the step of generating an automated locator graphic that is applied to a particular location on the selected image is performed in response to a user clicking on a feature of the selected image.

16. The method of claim 12 wherein the feature of the selected image is an edge feature.

17. The method of claim 12 wherein the step of applying one or more automated parameters to a desired orientation is in response to a user moving a feature of the selected image to a desired orientation.

18. The method of claim 17 wherein the moving step further comprises dragging, by the user, the feature of the selected image to the desired orientation.

21. The method of claim 14 wherein the user input comprises dragging an edge of the selected image to the desired orientation.

22. A method for displaying and controlling vision system operating parameters comprising the steps of:

displaying, on a graphical user interface (GUI) operated by a processor, a plurality of captured images within a field of view of a vision system imager;

receiving a selection of at least one image of the plurality of captured images that defines a selected image;

generating an automated locator graphic image that is applied to a particular location on the selected image based upon user selection of the particular location;

applying one or more automated operating parameters to a desired orientation of the selected image in response to a user dragging a feature of the selected image to the desired orientation;

displaying at least one user definable operating parameter of the one or more automated operating parameters in a separate control box displayed on the GUI, the at least one user definable operating parameter defining the automated locator graphic image and being in a non-numeric graphical format, the at least one user definable operating parameter including a scale and having a predetermined area and a user-movable setting graphic, wherein a feature of the user-movable setting graphic defines a level of the operating parameter; and

wherein a setting of the user-movable setting graphic of the locator graphic image is set in response to the user moving the user-movable setting graphic to a desired level of the operating parameter.

23. The method of claim 22 wherein the plurality of captured images respectively vary slightly as a result of relative motion within the field of view of the vision system imager.

24. The method of claim 22 wherein the feature of the selected image is an edge feature.
