Applications
Photometric Stereo (PMS)
Photometric stereo allows the user to separate the shape of an object from its 2D texture. It works by firing segmented light arrays from multiple angles and then processing the resulting shadows in a process called “shape from shading.” It is useful for the detection of small surface defects and 3D surface reconstruction. PMS is a height driven process which can enhance surface details like scratches, dents, pin holes, raised printing, or engraved characters. Because the final image is a computed surface based on the shading information surface coloring or features without height are removed.
This can make visually noisy or highly reflective surfaces easier to inspect. This capability is rapidly becoming popular in the MV market. Numerous machine vision suppliers are offering photometric stereo tools. A basic PMS system uses a ring light with four 90 degree quadrants to cast a directional shadow around raised features on an object. The feature map can be applied through different algorithms to show surface details that are hard to find or can’t be detected in pure visual images.
Tire inspection with PMS
The images in this example were captured with a ring light with four 90 degree quadrants. The quadrants were fired in sequence to create the West, North, South, and East images as shown on the right. Images of the Tire Texture and Tire Shape are then created by combining these images in software as shown. The PMS routine removes the visual noise and leaves only the features of interest.
Controllers for Sequence Control
With the sequence control function, you can program steps of ON input to turn lights on in desired pattern. For example, when using segmented ring lights, the emission patterns for each channel can be stored and switched ON / OFF by trigger input.PD4 Series
