3D shape measurement system based on line structure light stereo vision and fringe reflection
With the increasing commercial application of free-form surfaces, the profile measurement capability of related molds and optical components has become a key bottleneck in the development and application of free-form optics, and the demand for free-form optics inspection tools is also increasing. In this paper, we developed an integrated free-form optics profile measurement system based on the fringe reflection principle, and the system is also combined with a laser stripe stereo vision measurement capability. The developed system is capable of measuring both rough surfaces and smooth optical surfaces. The measurement experiments prove that the current developed system can measure free-form optics with a diagonal size of approximately 300 mm, and the measurement uncertainty within ±1 μm.
