📐 Laser-Stripe Triangulation Scanner on a Turntable: Baseline, Noise and Point Cloud (2D plan view)

2D top view of a structured-light scanner: a laser stripe sweeps a specimen on a turntable while a camera triangulates each point. Change the camera-laser baseline, pixel noise, laser jitter, dropout and turntable speed and watch the point cloud and reconstruction error build up. Same scanner model as the 3D page, with four in-page numerical checks.
