About this document
Four-Step Camera Calibration Method by dgrnwd is a document available to read on EtoBox.
This document describes a four-step camera calibration procedure that improves upon existing two-step methods. The four steps are: 1) estimating initial camera parameters using a direct linear transformation, 2) refining the parameters using nonlinear minimization, 3) compensating for distortions caused by circular control points, and 4) correcting distorted image coordinates using an empirical inverse distortion model. The procedure provides accurate camera calibration by addressing errors from control poi
