科研级精迅V1~V4！从零搭建一套面结构光扫描仪！提供源码+高阶班课程+答疑

TL;DR - Suzhou Sandisiwei (via the 3D视觉工坊 channel) is marketing its "精迅" V1–V4 research-grade structured-light 3D scanners, sold with full source code and bundled training courses on structured-light reconstruction and PCL point-cloud processing. It matters as an example of the commercial tooling layer feeding 3D perception for robot grasping, metrology, and defect inspection.

• Product tiers differ mainly by projector and camera: V1/V2 use a DLP3010 light engine (mono/stereo calibration, one-click reconstruction, point-cloud filtering), V3 moves to DLP4710 for higher resolution, stripe writing, and up to 1000 lm for outdoor/dark-object scenes (but >4 kg), and V4 uses a metrology-grade DLP4710 with interchangeable C-mount lenses, passive copper-tube cooling, and a 14 MP Hikvision global-shutter camera.
• V4 claims CUDA acceleration across reconstruction and point-cloud processing; the post shows capture-time comparisons for a CPU version (V2) vs GPU version (V4) at 30 FPS projection, with hardware supporting up to 60 FPS.
• Software is a Qt demo with source-level access: HDR multi-exposure fusion for shiny/black surfaces (aluminum, dark backgrounds), manual/feature-based point-cloud registration, SSD surface reconstruction to meshes, single-point and region measurement (flatness, sphericity), plus secondary development against OpenCV/Halcon/VisionMaster.
• Purchase bundles two video courses (advanced structured-light reconstruction; PCL/Qt/VTK point-cloud processing); no independently verified accuracy or throughput figures are given in the text — performance tables and sample reconstructions (calipers, coins, blades, plaster bust) are referenced as images only.
