Photometirc Application

Photometric Stereo Lighting & Preprocessing Algorithm

We introduce a new product lineup enabled by high-precision optical systems based on photometric stereo technology, delivering precise analysis and reliable results.
By reconstructing surface geometry three-dimensionally under various lighting conditions, the system can reliably detect fine protrusions, dents, scratches, and stains, thereby improving inspection efficiency and reducing quality control costs.
