  Robustness and accuracy are two critical metrics for industrial inspection.
In this paper, we propose benchmarks that can evaluate the structured light
method's performance. Our evaluation metric was learning from a lot of
inspection tasks from the factories. The metric we proposed consists of four
detailed criteria such as flatness, length, height and sphericity. Then we can
judge whether the structured light method/device can be applied to a specified
inspection task by our evaluation metric quickly. A structured light device
built for TypeC pin needles inspection performance is evaluated via our metrics
in the final experimental section.
