CalibrX Blog
Practical guides for camera calibration teams.
Learn how to capture better calibration data, choose target patterns, read solver quality, undistort images, and export parameters for production computer vision systems.
What Is Camera Calibration? A Scientific Introduction
A scientific walkthrough of the pinhole model, intrinsics, distortion, and the optimisation problem solved by camera calibration — written for engineers who want to know not just what to do, but why.

Pinhole, Wide, or Fisheye? Choosing the Right Camera Model
Compare the standard pinhole, rational pinhole-wide, and Kannala–Brandt fisheye models — their math, their assumptions, and how to decide which one fits your lens.
Read guideThe Complete Camera Calibration Workflow: From Sample Images to Production Parameters
A long-form guide to the full calibration journey: capture strategy, pattern detection, validation, camera model selection, undistortion, quality checks, and structured exports.
Read guideEducational content that maps to real calibration questions.
The blog is organized around the questions engineers already search for: what calibration is, how undistortion works, which pattern to use, and how to interpret reprojection error before shipping a vision system.
