[Termes IGN] Triangulated Irregular NetworkRésumé : (Auteur) As a result of new sensors and methodologies that allow for faster and more accurate data acquisition, the production of highly detailed 3D models is becoming part of the standard workflow in many disciplines – architecture, cultural heritage, urban planning, and others. At the same time, new related problems have emerged concerning the management of the resulting large datasets and the integration of data coming from different sources. Data integration among heterogeneous datasets can lead to a variety of errors, and the reasons for these errors are multiple including geometric, topological or semantic incompatibilities, different resolutions and accuracies, and data acquired at different times. To overcome such errors, the integration of heterogeneous datasets requires appropriate homogenisation techniques. This article presents a new deterministic approach for the integration of a high resolution surface model and a lower resolution surface model, both given as triangular meshes embedded in 3D space, by means of a transition surface. The method can be applied after both datasets have been aligned. The derivation of the transition surface exploits extra data that are typically available in the high resolution model. These extra data (e.g. quite common when using a laser scanner) must be 2.5D and located around the high resolution model, they represent a sort of planimetric buffer around the high resolution object that can be thought as a “collar”. The proposed method generates a geometrically and topologically sound and continuous 2.5D surface that integrates the two models using the data contained in the collar. It takes into account the different quality aspects of the low and high resolution models such as point height, point density, and height gradient, and then creates a transition surface that interpolates these aspects between the embedded high resolution model and the surrounding low resolution model. The article also presents some experimental results, obtained from real datasets, and concludes with some remaining issues and possible improvements to the method.

[Termes IGN] série de FourierRésumé : (Auteur) This paper presents a new family of rigorous and flexible mathematical self-calibration additional parameters (APs) for airborne camera calibration. Photogrammetric self-calibration can – to a very large extent – be considered as a function approximation problem in mathematics. It is shown, that algebraic polynomials are less desirable for designing self-calibration APs due to the highly correlated terms. Based on the mathematical approximation theory, we suggest that Fourier series be the optimal mathematical basis functions for self-calibration purpose. A whole family of so-called Fourier self-calibration APs is developed, whose solid theoretical foundations are the Laplace’s Equation and the Fourier Theorem. Fourier APs are orthogonal, rigorous, flexible, generic and efficient for calibrating the image distortion of frame-format airborne cameras. The high performance of Fourier APs is demonstrated in many practical tests on different camera systems, including the DMC, DMCII, UltracamX, UltracamXp and DigiCAM cameras. We illustrate the theoretical and practical advantages of the Fourier APs over the physical APs and the popular polynomial APs. The joint applications with physical models are promoted for specific applications as well. On account of the theoretical justifications and high practical performance, Fourier APs should be preferred for in situ airborne camera calibration.

[Termes IGN] transformation de coordonnéesRésumé : (Auteur) We define as Positional Accuracy Improvement the problem of putting together maps A and B of the same area, with B of higher planimetric accuracy. To do so, all objects in A might have to be slightly moved according to a mathematical transformation. Such transformation might ideally be of a specific type, like analytical or conformal functions. We have developed a theory to find a suitable analytical transformation despite it is not well defined because the only data available is the displacement vectors at a limited number of homologue control points. There exists a similar problem in fluid mechanics devoted on estimating the complete velocity field given just values at a limited number of points. We borrowed some ideas from there and introduced them into the positional accuracy improvement problem. We shall demonstrate that it is possible to numerically estimate an analytic function that resembles the given displacement at control points. As a byproduct, an uncertainty estimation is produced, which might help to detect regions of different lineage. The theory has been applied to rural 1:50.000 cartography of Uruguay while trying to diminish the discrepancies against GNSS readings. After the analytic transformation, the RMSE error diminished from 116m to 48 m. Other problems with similar math requirements are the transformation between geodetic control networks.

[Termes IGN] point de repèreRésumé : (Auteur) In an historically contextualized overview of the earliest extant version of the Tujitu, engraved on stone under the Liu Yu regime but believed to be a copy of a Northern Song map, the paper analyzes factors that complicate its georeferencing. The paper introduces a new algorithm for nonlinear georeferencing, applying it to 45 points and finding that the placement of sites on the north-south axis must have been based on latitudinal observation. Despite the Yujitu's startlingly modern appearance, the paper finds that there are areas in which it reflects a loyalty to classical texts.

[Termes IGN] peintureRésumé : (auteur) Matteo Giovannetti's frescoes (1355–1356) which decorate the Innocent VI chapel of La Chartreuse du Val des Bénédictins (Villeneuve-lez-Avignon, France) are very sensitive to the alteration. They need a new restoration campaign. Because of the geometrical complexity of the place, the environment and the involved degradation mechanisms, a good conservation management of these murals is essential. Therefore, an interactive 3- dimensional spatial database, including dated data was developped. Architectural measurements, digital scientific documentation were gathered. A historical documentation including restoration acts, used restoration products has been collected. Last, the paintings degradations, up-to-date deterioration patterns description and conservation state diagnosis of these wall paintings including a deterioration mapping are monitored. Results of the physical and chemical analyses of painting, restoration techniques and deterioration products are also integrated. The entire collected and interactive database will be available for conservation managers and researchers within the next three years.
