Detection of Outer Diameter of Smooth Iron Cylinders
Detection Content: Detection of Outer Diameter of Smooth Iron Cylinders
Light Source Used: Surface Light Source
Analysis: Using a conventional surface light source for backlighting results in a diffuse effect, causing a gray band along the edge of the cylinder with reduced sharpness.
Light Source Used: Parallel Surface Light Source
Analysis: Utilizing a parallel surface light source for backlighting provides sharp edges along the cylinder under parallel illumination, facilitating dimensional inspection.
