How do Vision Sensors Work

Vision sensors locate a part and then apply vision tools to inspect features

Vision sensors perform inspections first by locating the part in the image, then by looking for specific features on that part. Once the field of view (FOV) is set, an operator can run vision tools within the entire range of the target to inspect multiple features for their presence, completeness, or orientation—all in a single image. And even though data output is binary, data in aggregate can be used downstream to improve processes and perform diagnostics on a particular work cell.

Vision Sensor Capabilities

A network of vision sensors can be easily linked to plant and enterprise networks, allowing any workstation in the factory to view results, images, and data for process control. Depending on the specific system or application, vision software configures camera parameters, makes the pass/fail decision, communicates with the factory floor, and supports HMI development. Most vision sensors:
  • Require no programming
  • Provide easy guided set-up through user-friendly vision software interfaces
  • Integrate easily into larger systems
  • Provide single- and multiple-point inspections with dedicated processing
  • Offer built-in Ethernet communications
  • Can exchange data with other systems to communicate results and trigger subsequent stages of an inspection

Vision Sensor Process

Vision sensors combine the power of a machine vision system with the simplicity and affordability of an industrial sensor, easily solving simple inspections and communicating results.
