PRECISE MEASUREMENT

Left: A back-lit image of M5 metallic washer is used as input.

Right: The washer is tested for its circularity and center. The outer diameter has 94.49% circularity while the inner has 91.88%. The center of outer diameter and inner diameter are indicated in green dots. This hole of this washer misaligned its center by 14 pixels and can be calibrated to 0.98 mm. (The images are cropped for illustration)

Introduction

Measurement is a baseline for all engineering and improvement, but, for a detailed product, it tends to be such a delicacy and careful task which might depends on the measurer. This solution will provide you a standard, accurate, user-independent tool to measure your product. With 5 mega-pixel camera, resolution of 0.02 mm can be achieved.
