“…The pinhole model has been enhanced by adding various terms for radial, tangential, and other distortions. The most widely established models are described for example in [63,64,149,152,451]. The usual model for combining radial and decentering distortion (one type of tangential distortion) is:…”

Different technologies and different computational models thereof exist and algorithms and theoretical studies for geometric computer vision ("structure-from-motion") are often re-developed without highlighting common underlying principles. One of the goals of this survey is to give an overview of image acquisition methods used in computer vision and especially, of the vast number of camera models that have been proposed and investigated over the years, where we try to point out similarities between different models. Results on epipolar and multi-view geometry for different camera models are reviewed as well as various calibration and self-calibration approaches, with an emphasis on non-perspective cameras. We finally describe what we consider are fundamental building blocks for geometric computer vision or structure-from-motion: epipolar geometry, pose and motion estimation, 3D scene modeling, and bundle adjustment. The main goal here is to highlight the main principles of these, which are independent of specific camera models

ABSTRACT:Photogrammetry has been widely used in the recent years in a number of applications, e.g. cultural heritage, surveying buildings and infrastructures. Despite nowadays its use is quite common, most of the used photogrammetric softwares are commercial. This paper aims at comparing the use of a free Matlab tool that is being developed at the University of Padova mostly for educational purposes with that of a commercial (and widely used) software (Agisoft PhotoScan). Despite the above mentioned free Matlab tool is designed to work for airborne photogrammetric, in this work it is used in a slightly different case: the 3D reconstruction of a low relief of the walls of Padova, which is on the façade

“…Several calibration models have been theorized for photogrammetric purposes, but sensor calibration and orientation are usually done via a perspective geometrical model by means of the bundle adjustment (Brown, 1971). The mathematical model is provided by the non-linear collinearity equations, usually extended by additional parameters (Fraser, 1997), and needs approximate values of unknowns and an iterative strategy to obtain the coordinates of the points and their precision parameter estimation (Gruen & Huang, 2003). The growing employment of low cost sensors for the generation of 3D models through a SfM approach and the possibility to perform a self-calibration of the cameras underlined the need to investigate a more robust method for the self-calibration of these sensors (Calantropio, et al, 2017).…”

“…With the interest of verifying how the choice of a different calibration model affects the relative orientation and the object reconstruction, two calibration models have been chosen; the Brown (Brown, 1971) and the Fraser (Fraser, 1997). The first test that has been performed is the analysis of the tiepoints residual; the generation of a coloured 3D model, with a colour related to the residuals of each tie-points allow to evaluate the part of the model with a good geometry.…”

ABSTRACT:Due to the increasing number of low-cost sensors, widely accessible on the market, and because of the supposed granted correctness of the semi-automatic workflow for 3D reconstruction, highly implemented in the recent commercial software, more and more users operate nowadays without following the rigorousness of classical photogrammetric methods. This behaviour often naively leads to 3D products that lacks metric quality assessment. This paper proposes and analyses an approach that gives the users the possibility to preserve the trustworthiness of the metric information inherent in the 3D model, without sacrificing the automation offered by modern photogrammetry software. At the beginning, the importance of Data Quality Assessment is outlined, together with some recall of photogrammetry best practices. With the purpose of guiding the user through a correct pipeline for a certified 3D model reconstruction, an operative workflow is proposed, focusing on the first part of the object reconstruction steps (tie-points extraction, camera calibration, and relative orientation). A new GUI (Graphical User Interface) developed for the open source MicMac suite is then presented, and a sample dataset is used for the evaluation of the photogrammetric block orientation using statistically obtained quality descriptors. The results and the future directions are then presented and discussed.
