The main purpose of this research is to eliminate dependence on ground calibration sites using relative constraints between images. Based on a systematic analysis of these relative constraints, we found that it was difficult, if not impossible, to completely eliminate ground constraints, although the number of ground control points (GCPs) required can be greatly reduced. To achieve practical GC with high accuracy and low cost, we proposed a new method to compensate for systematic errors in linear optical satellite data acquisition using only the relative constraints between two overlapped images, namely, the corresponding elevation constraints and sparse GCPs. We first demonstrated the feasibility of GC with relative constraints and established an optimized GC model suitable for these relative constraints. We then presented a global iterative method to eliminate inaccuracies in internal calibration caused by the different distributions of GCPs within two images. The nadir (NAD) linear camera on board the Zi-Yuan 3 (ZY-3) satellite was used to evaluate the feasibility of the presented GC method; the results indicated that the present method effectively compensated for systematic errors. Thus, this article demonstrated the feasibility of GC without calibration sites.

Three-point-based solution for automated motion parameter estimation of a multi-camera indoor mapping system with planar motion constraint / Fangning He in ISPRS Journal of photogrammetry and remote sensing, vol 142 (August 2018)  

Public [article]  inISPRS Journal of photogrammetry and remote sensing > vol 142 (August 2018) . - pp 278 - 291 Titre : Three-point-based solution for automated motion parameter estimation of a multi-camera indoor mapping system with planar motion constraint Type de document : Article/Communication Auteurs : Fangning He, Auteur ; Ayman Habib, Auteur Année de publication : 2018 Article en page(s) : pp 278 - 291 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Traitement d'image [Termes IGN] appariement d'images [Termes IGN] carte d'intérieur [Termes IGN] compensation par faisceaux [Termes IGN] coplanarité [Termes IGN] élément d'orientation interne [Termes IGN] modélisation 3D [Termes IGN] orientation relative [Termes IGN] Ransac (algorithme) [Termes IGN] reconstruction 3D [Termes IGN] structure-from-motion [Termes IGN] valeur aberrante Résumé : (auteur) Accurate indoor 3D models have become a key prerequisite for various applications. Through state-of-the-art image processing techniques, 3D models can be generated from high quality images captured by off-the-shelf digital cameras. To acquire redundant data and produce real scale models, a multi-camera system can be used. However, dedicated approaches for image-based 3D reconstruction using mapping platforms equipped with multiple cameras have not been fully addressed. Assuming the availability of prior information regarding the platform trajectory, this paper presents a new approach for reliable estimation of system motion parameters between different data acquisition epochs of a multi-camera system. This approach, which assumes planar motion of the utilized platform, provides a three-point closed-form solution. The derived solutions are then incorporated within a modified RANSAC framework for outlier detection/removal. It is worth noting that, different from the existing General Camera Model (GCM)-based solutions, the proposed approach is based on a modified co-planarity model, which is essentially a direct extension of the classic stereo-based relative orientation. Moreover, since the proposed approach only provides a maximum number of four possible solutions for system motion parameters over different epochs, it has better computational efficiency when compared to other existing algorithms. Experimental results from real datasets acquired with different configurations have demonstrated the reliability of the proposed approach in motion parameter estimation for indoor multi-camera mapping systems.

Geometric model and assessment of a dual‐fisheye imaging system / Mariana Batista Campos in Photogrammetric record, vol 33 n° 162 (June 2018)  

Public [article]  inPhotogrammetric record > vol 33 n° 162 (June 2018) . - pp 243 - 263 Titre : Geometric model and assessment of a dual‐fisheye imaging system Type de document : Article/Communication Auteurs : Mariana Batista Campos, Auteur ; Antonio Maria Garcia Tommaselli, Auteur ; José Marcato, Auteur ; Eija Honkavaara, Auteur Année de publication : 2018 Article en page(s) : pp 243 - 263 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Acquisition d'image(s) et de donnée(s) [Termes IGN] chambre panoramique [Termes IGN] compensation par faisceaux [Termes IGN] élément d'orientation interne [Termes IGN] étalonnage de chambre métrique [Termes IGN] lentille [Termes IGN] panorama sphérique Résumé : (Auteur) This paper presents a technique for the calibration of a 360° dual imaging system (Ricoh Theta S) composed of two cameras with fisheye lenses specially mounted in a common structure. The experiments are based on calibration with a bundle adjustment using the equidistant fisheye lens model and relative orientation stability constraints, such as distance, base elements and rotation matrix between individual cameras’ coordinate systems. As a result, an equidistant mathematical model using the Conrady–Brown lens distortion model was shown to be suitable for estimating the interior and relative orientation parameters of the Ricoh Theta S. The main contribution presented in this work is a simultaneous bundle adjustment approach with stability constraints on base elements and rotation matrix angles, which achieved accuracies comparable with conventional photogrammetric calibration with perspective cameras.

This approach is particularly suitable for reduction of data from non-metric photography, but has also distinct advantages in its application to metric photography. Preliminary fictitious data tests indicate that the approach is promising. Experiments with real data are underway. NB : The original article was published in 1971 as part of committee work within ASP (the original name for ASPRS), but it has not appeared in PE&RS or other journals, as far as we know.

A flexible mathematical method for calibration in digital aerial photogrammetry / Rongfu Tang in Photogrammetric Engineering & Remote Sensing, PERS, vol 78 n° 10 (October 2012)

This paper presents a new family of self-calibration additional parameters (aps) for digital airborne camera calibration. Photogrammetric self-calibration can (to a very large extent) be considered as a function approximation problem in mathematics. Based on the rigorous approximation theory, a new family of so-called Legendre self-calibration APs is developed from the orthogonal Legendre Polynomials. An approach is suggested to assess the full potential of in-situ camera calibration. The performance of Legendre aps is investigated in many field tests on the DMC, UltracamX, UltracamXp and DigiCAM camera systems. The external accuracy in the tests can reach 0.2 GSD and 0.4 GSD in horizontal and vertical dimensions, respectively. The posterior standard deviation estimation of image measurements is approx. 0.12 pixel or even less. The advantages of Legendre aps are illustrated over the conventional counterparts. From both the theoretical and practical views, Legendre aps are orthogonal, rigorous, flexible, and effective for calibrating frame-format airborne cameras.
