measuring metal surface smoothness
Hello,
How can I measure a metal surface smoothness? It has 0.2 mm tolerance, I will watch it by camera. Can I see the metal size is within tolerance? Is it possible, can I get the information about the metal surface roughness?
what kind of camera is it ? RGBD, stereo, mono, gray/color ?
what kind of kamera should i use?, is casually webcam enough?
