PROOF
Some applications fail because the part is difficult to image, not because the camera is “bad”. The engineering challenge is to control optics, lighting, geometry, algorithms and integration together.
Subtle defects can disappear when illumination and surface response are not engineered around the defect signature.
Specular reflections can overwhelm the feature of interest. Lighting and optical geometry become part of the solution.
Fast moving parts require controlled exposure, triggering and processing so image quality survives cycle-time constraints.
When height, profile or form matters, 2D images may not contain enough information. 3D sensing can become essential.
AI and robust inspection logic can help distinguish acceptable variation from meaningful defects when rules alone are brittle.
A working inspection result must also trigger the right machine action, traceability event or operator workflow.
