Emerging Topics in Computer Vision

2.1. Introduction

Much work in camera calibration has been done in the photogrammetry community (see [3, 6] to cite a few) and more recently in computer vision ([12, 11, 33, 10, 37, 35, 22, 9] to cite a few). According to the dimension of the calibration objects, we can classify those techniques roughly into four categories.

3D reference object-based calibration. Camera calibration is performed by observing a calibration object whose geometry in 3D space is known with very good precision. Calibration can be done very efficiently [8]. The calibration object usually consists of two or three planes orthogonal to each other. Sometimes, a plane undergoing a precisely known translation is also used [33], which equivalently provides 3D reference points. ...
