Flexible Flaw Detection

Inspect for boundary and surface defects

Flexible Flaw Detection edge inspection tool finding printing error on number 5

Without flexible tools, normal process variation can cause false rejects during inspection. Cognex Flexible Flaw Detection (FFD) offers accurate edge and surface inspection when dealing with lens and perspective distortion, scale changes, print registration errors, and stretching from line scan images. FFD is the ideal tool with which to inspect for boundary defects, such as conformity of shape, and surface defects like stains and scratches. FFD can also be used for print inspections, like inspecting screened logos for defects.

Flexible Flaw Detection is ideal for edge- and area-based inspection of shapes. To find edges and boundaries under error-prone conditions, FFD compares edges in a trained model to edges in the run-time image to check for extra or missing edges. FFD works for both color and greyscale applications, giving users the flexibility to balance accuracy versus speed, and even to ignore defects during run-time.
