Abstract

A method is disclosed for instructing a user interface (UI) in communication with a first of vision processor (VP) to establish communication with a second (VP). The invention is useful in a machine vision system having a plurality of VPs and at least one UI. The method includes the steps of providing each VP with a link function for establishing communication between a VP and a UI; and activating the link function so as to issue instructions to the UI to establish communication with another VP. The link function enables local dynamic display of a remote VP on the UI, and a dynamic connection that provides a continually updated display representing a current state of the VP connected to the UI. An operator may observe results and alter parameters on any of the VPs in the system without having to first understand the architecture of the machine vision system.

Claims

1. A machine vision system comprising:

a first vision processor (VP) on a first VP computing platform and a second vision processor (VP) on a second VP computing platform, the first VP computing platform and the second VP computing platform being connected to a network; and

at least one machine vision user interface (UI) in communication via the network with the first VP, the at least one machine vision UI including a graphical representation of a link function that enables configuration of the second VP using the at least one machine vision UI in communication with the first VP;

wherein the first VP instructs the second VP to perform at least part of a machine vision task, the machine vision task being configured by the at least one UI through the first VP to perform at least part of the machine vision task upon execution of the link function from the first VP to establish communication between the second VP and the machine vision UI.

2. The machine vision system of claim 1 wherein execution of the link function is initiated by a user selecting the graphical representation of the link function on the machine vision UI.

3. The machine vision system of claim 1 wherein execution of the link function is initiated automatically by the first VP when an appropriate condition is met.

4. The machine vision system of claim 1 wherein the network is supported by any application layer protocol running on the network.

5. The machine vision system of claim 1 wherein the network comprises one of a TCP/IP 10/100-base-T Ethernet network, an ATM network, a wireless network and a gigabit Ethernet network.

6. The machine vision system of claim 1 wherein execution of the link function establishes communication between the second VP and the machine vision UI until a condition is met and thereafter establishes communication between the first VP and the machine vision UI.

7. The machine vision system of claim 1 wherein the graphical representation of the link function is an underlined text string displayed by the machine vision UI.

8. The machine vision system of claim 1 wherein executing the link function is initiated by at least one of a programmatic decision, a change in a state of a sensor and a user input.

9. A method for instructing a machine vision user interface (UI) to establish communication with vision processors (VPs), the method comprising the steps of:

providing a first VP with an executable control function for establishing communication with a second VP to enable configuration of the second VP using a machine vision UI connected to the network and in communication with the first VP;

executing the executable control function, when a condition is met, to issue instructions via the network from the first VP to the machine vision UI to establish communication via the network with the second VP; and

performing a machine vision task configured by the machine vision UI in accordance with instructions issued by the first VP.

10. The method of claim 9 wherein the step of executing the executable control function is initiated by user action of selecting a graphical representation of the executable control function.

11. The method of claim 9 wherein the step of executing the executable control function is initiated when a particular string of barcode is read by a barcode reading function.

12. The method of claim 9 further comprising the steps of:

terminating communication between the machine vision UI and the second VP; and

establishing communication between the machine vision UI and the first VP.

13. The method of claim 9 wherein the step of executing the executable control function is initiated by an external causal agent based on at least one of:

a change in the state of a sensor, a programmatic decision based on the mechanical, electrical or software state of a computer, and a human-machine interaction input.

14. The method of claim 9 wherein the network is supported by any application layer protocol running on a communications medium.

15. The method of claim 9 wherein the network comprises one of a TCP/IP 10/100-base-T Ethernet network, an ATM network, a wireless network and a gigabit Ethernet network.

16. The method of claim 9 wherein the link function enables local dynamic display of images provided by the second VP on the machine vision UI.

17. A user interface (UI) display for a machine vision system having a plurality of distinct and separate vision processors (VPs) each respectively on distinct and separate VP computing platforms, the user interface comprising:

a graphical representation on the UI display, the graphical representation executable in response to a condition being met so as to cause a first VP on a first respective VP computing platform to instruct the UI display to establish communication via a network with a second VP on a second respective VP computing platform, the communication established with the second VP enabling display of a continually updated image on the UI display representing a current state of the second VP such that the second VP is configurable using the UI display; and

wherein at least one of the first VP and the second VP performs at least part of a machine vision task in accordance with instructions issued by the first VP, the machine vision task being configured by the UI display.

18. The UI display of claim 17, wherein the condition being met is one of a user action and an external event.

19. The UI display of claim 17 further comprising a spread sheet that incorporates the graphical representation.

20. The UI display of claim 17 wherein the graphical representation is one of an underlined text string and an iconic representation.
