Captured the texture of artificial leather with TR-100, observing the color patterns and "shape" separately in a single shot.
We have published an observation record of red artificial leather with a grain pattern (embossed surface) captured using "TR-100" (technology: FORESIGHT STEREO). This is a commercially available standard product and not a defective sample.
■ Four images from a single capture
From eight images taken with lighting directions changed in eight ways, we output Live / 2D Texture / 3D Surface / Surface Normal.
■ Color patterns and textures have "different shapes"
When enlarged, patterns that appear as wide bands and islands in color show up as fine grooves in the 3D Surface.
■ Consideration materials for shape-related items
This may be useful for examining scratches, grain flattening, foreign objects, wrinkles, and more. Evaluation with defective samples is yet to come.
We accept inquiries for sample photography.
