Abstract

A method, a system and a computer-readable storage medium having stored therein a program for interactively developing a graphical control-flow structure and associated application software for use in a machine vision system is provided. The structure is a tree view structure including a control sequence having at least one node. The method includes providing a first set of control programs representing possible machine vision tasks. The first set of control programs defines a first set of standard controls. Hardware operating parameters are provided which correspond to possible hardware. The hardware operating parameters defining a second set of standard controls. Graphical representations of possible hardware and possible machine vision tasks are displayed. Commands are received from a user to select desired hardware operating parameters corresponding to desired hardware and a machine vision graphical representation and its associated first control program corresponding to a desired machine vision task. The tree structure is displayed wherein the selected machine vision graphical representation is a node of the structure and the first control program is linked into the structure. A plurality of separate application processing engines interlinked together are provided for seamlessly communicating results obtained by execution of the selected first control program. The selected first control program is linked with the desired hardware operating parameters to form the application software in response to the commands without the user writing any of the application software.
