Vision Inspection Functionality

Cognex Corporation (Natick, MA) has introduced a TestRun feature for its In-Sight® vision systems. The TestRun functionality allows users to confirm program changes by quickly checking against a “baseline” configuration. TestRun also makes it easy for system integrators and OEMs to demonstrate that the vision system meets acceptance criteria when the system is installed at the end user’s facility.

altTestRun provides application validation against an image database. When TestRun executes, each image in the library is evaluated by the current vision program. TestRun confirms that the results from the current vision program match the “expected” results.

Hardware tests measure the integrity of the image acquired by the vision system by checking factors such as the focus, position, and the illumination of the current system. Users can set up a test routine configuration. The VisionView™ operator interface is used to execute TestRun on the shop floor. With the TestRun Plug-in, an operator can perform the test routines on all systems attached to the VisionView.
