Digital camera self-calibration
TLDR
This paper reviews the application of analytical self-calibration to digital cameras and an overview is given of each of the four main sources of departures from collinearity in CCD cameras.Abstract:
Over the 25 years since the introduction of analytical camera self-calibration there has been a revolution in close-range photogrammetric image acquisition systems. High-resolution, large-area ‘digital’ CCD sensors have all but replaced film cameras. Throughout the period of this transition, self-calibration models have remained essentially unchanged. This paper reviews the application of analytical self-calibration to digital cameras. Computer vision perspectives are touched upon, the quality of self-calibration is discussed, and an overview is given of each of the four main sources of departures from collinearity in CCD cameras. Practical issues are also addressed and experimental results are used to highlight important characteristics of digital camera self-calibration.read more

Random sample consensus: a paradigm for model fitting with applications to image analysis and automated cartography
TL;DR: New results are derived on the minimum number of landmarks needed to obtain a solution, and algorithms are presented for computing these minimum-landmark solutions in closed form that provide the basis for an automatic system that can solve the Location Determination Problem under difficult viewing.

What can be seen in three dimensions with an uncalibrated stereo rig
TL;DR: This paper addresses the problem of determining the kind of three- dimensional reconstructions that can be obtained from a binocular stereo rig for which no three-dimensional metric calibration data is available, and shows that even in this case some very rich non-metric reconstructions of the environment can nonetheless be obtained.

A theory of self-calibration of a moving camera
TL;DR: The feasibility of camera calibration based on the epipolar transformation is demonstrated and two curves of degree six can be obtained in the dual plane such that one of the real intersections of the two yields the correct camera calibration.

Techniques for calibration of the scale factor and image center for high accuracy 3-D machine vision metrology
R.K. Lenz,Roger Y. Tsai +1 more
TL;DR: Three groups of techniques for center calibration are presented: Group I requires using a laser and a four-degree-of-freedom adjustment of its orientation, but is simplest in concept and is accurate and reproducible; Group II is simple to perform,but is less accurate than the other two; and the most general, Group II, is accurate, but requires a good calibration plate and accurate image feature extraction of calibration points.
