Dot Grid vs. Checkerboard: Which Calibration Target Is Right for Your Machine Vision System?
If you’re setting up a machine vision system — whether it’s for factory inspection, robotics, or 3D measurement — you’ve probably run into one question pretty quickly: Should I use a dot grid or a checkerboard calibration target? It sounds like a simple choice. But the wrong target can cost you hours of rework, inconsistent […]

Chapter 3: Calibration Patterns｜Understanding Calibration Patterns: The Foundation of Accurate Camera Calibration
What is Calibration Pattern? Calibration patterns serve as the bridge between the physical world and digital camera measurements. These precisely manufactured targets provide known reference points that enable calibration algorithms to calculate camera parameters with high accuracy. Selecting the right pattern directly impacts calibration quality, affecting everything from distortion correction to 3D reconstruction precision. Types […]
