What inspection variables should be evaluated?
Dents and creases distort patterns. Test different directions and separate defects from smooth deformation caused by normal curvature.
What lighting geometry fits this inspection task?
Patterned illumination uses changes in a reflected pattern to examine surface shape. Stable viewing angle and part pose help distinguish pattern deformation from printed texture.
Oblique or low-angle lighting can darken a smooth background while allowing scattered light to reach the camera. Scratch visibility depends on direction, depth and illumination angle. Separate images from several directions may be needed.
Hold the part fixed and vary the light direction. Compare normal texture with actual defects rather than judging brightness alone. Check shadows, curved-surface highlights and motion blur. Repeat the test at production speed and across the permitted position variation before choosing a layout.

Before choosing a configuration?
For selection, specify the field of view, smallest target feature, height variation, cycle time and installation space. Use the specific product page and drawing to verify electrical ratings, dimensions and compatibility.
Comparing a pattern with a clean reference?
Set up a reflected stripe pattern on a known good surface before testing dents or folds. Keep the camera, source and part geometry consistent so that a pattern change can be associated with the sample.
Test shallow features in several directions and locations. Check sensitivity to normal curvature and pose variation. Use the pattern image as inspection evidence without assigning a defect depth unless the complete measurement method has been calibrated.
