3D scanning test for small items

[Fly]

Utilize a modified industrial projector paired with a telephoto lens to achieve high-detail scanning of small items.https://www.bilibili.com/video/BV1GBu3z ... e10d05a27b

Why place the projector so far from the object? The projection module is very similar to the Lightcrafter 4700, similar to the one used in the LG PF1500/HF60 household projector, and it focuses normally from a distance of 24-26 cm. At the same time, a higher density of projection pixels per unit area of the object's surface is achieved. It is quite possible to scan objects from 10-15 mm. In the example - a fairly shiny coin with a diameter of 15.5 mm with the LG PF1500 projector and Daheng MER2-630 cameras
