For simple barcode labels, Zebra Fixed Industrial Scanners provide a compact all-in-one solution for verifying label presence and contents in manufacturing and logistics environments. Integrated optics and lighting simplify integration, whilst the built-in Aurora Focus code-reading software streamlines the setup and configuration of code-reading applications into a simple 3-step process. Fixed scanners can be configured to trigger on presence for simple overhead scanning applications or paired with external triggers for automated workflows. A simple license upgrade provides access to additional machine vision tools, such as Deep Learning-based OCR for additional label verification checks.
For more sophisticated label inspection requiring presence/absence verification of the label and individual elements within, Zebra smart cameras, such as NS42 Smart Vision Sensor or the Iris GTX, provide a compact yet powerful solution. Move beyond presence checks by setting tolerance windows for X‑Y position and rotation. This flags skewed or misplaced labels before they cause rework. If a product doesn’t pass inspection, the smart camera can send data to automatically divert it via a reject mechanism, while good items advance. Position, result data, and optional images can be saved with warehouse or production systems for full traceability and root cause analysis.
Aurora Design Assistant machine vision software provides a wealth of field-proven templates and tools for label verification applications, including Locate Object, Locate Edge, and Locate Circle tools that confirm label presence and position even when packages shift or lighting changes. Edge detection locks borders; circle finding anchors to fiducials, such as holes, marks, or graphics. Each inspection returns X‑Y coordinates, rotation, confidence score, and pass/fail against set tolerances. This removes manual checks, relieves bottlenecks at print‑and‑apply, and improves label accuracy on high‑throughput lines.
