3D Machine Vision Imaging Methods: A Complete Comparison Guide (2026)

There are four mainstream methods for 3D imaging in machine vision — stereo vision, structured light, time-of-flight (ToF), and laser triangulation. Each has distinct strengths in accuracy, speed, range, and cost. This guide breaks down how they work, when to use them, and why calibration quality is the foundation of every 3D vision system.
Which Calibration Chart Material Is Best? PE vs Film vs Paper

White PE calibration charts offer 30μm precision and industrial durability with front lighting. White Film provides 0.3mm resolution with backlight compatibility. Photo Paper delivers color accuracy for controlled environments. Each material has specific advantages for different imaging applications.
