[Termes IGN] translationRésumé : (Auteur) Three-dimensional (3D) feature-matching techniques, which are essential for progress towards an automated feature-based procedure, have attracted considerable research attention in both the photogrammetry and computer vision communities. This study introduces a novel matching approach, called RSTG, that comprises four major phases: rotation alignment; scale estimation; translation alignment; and geometry checks. These steps efficiently determine a feature-based correspondence and frame transformation between datasets. RSTG analyses the similarity and relative geometry of features by employing feature observations and their uncertainty; this allows different types of features to be matched exclusively or simultaneously. This study validates the proposed method with both simulated and real datasets, demonstrating its effectiveness with satisfactory matching rates in a diverse range of feature-based point cloud registration tasks.

[Termes IGN] télémétrie laser mobileRésumé : (Auteur) Road roughness is the deviation of a road surface from a designed surface grade that influences safety conditions for road users. Mobile laser scanning (MLS) systems provide a rapid, continuous and cost-effective way of collecting highly accurate and dense 3D point-cloud data along a route corridor. In this paper an algorithm for the automated estimation of road roughness from MLS data is presented, where a surface grid is fitted to the lidar points associated with the road surface. The elevation difference between the lidar points and their surface grid equivalents provides residual values in height which can be used to estimate roughness along the road surface. Tests validated the new road-roughness algorithm by successfully estimating surface conditions on multiple road sections. These findings contribute to a more comprehensive approach to surveying road networks.

[Termes IGN] positionnement automatiqueRésumé : (Auteur) The objective of the proposed approach is to locate and measure ground control points in aerial images when large image search spaces are defined due to the use of inaccurate initial exterior orientation parameters, such as those provided by consumer-grade navigation systems. Vertical terrestrial image patches covering control point areas are generated and compared with aerial patches using feature- and area-based matching algorithms to automatically determine their corresponding positions in aerial images with sub-pixel precision. The approach is based on techniques for both image search space reduction and adaptive least squares matching. Experiments with real data were performed with bundle block triangulation and the results were analysed using control and check points in both object and image spaces. The proposed technique enabled a significant reduction in the search space within which it was feasible to successfully locate control points. Compared with manual measurements, the results obtained by the automatic technique were more accurate, achieving one-fifth of the ground sample distance in planimetric check point discrepancies.

[Termes IGN] traitement d'imageRésumé : (Auteur) Camera–projector systems are increasingly being used in many different applications, including object reconstruction. In recent years, a number of approaches have been proposed to calibrate such devices; in this paper a calibration method is presented which can be used with monochromatic systems. The method is based on open-source code, makes use of planar calibration patterns, is fully automatic, easy to use and fast. Additionally, no initial information regarding the camera interior orientation is needed, and both sensors (camera and projector) are fully calibrated during the process. The method is validated by a series of tests, where root mean square errors (RMSEs) in image space are kept below 1 pixel. Finally, the applicability of the method is demonstrated by implementing two different strategies to automatically reconstruct objects.

[Termes IGN] fonction de transfert de modulationRésumé : (Auteur) The modulation transfer function (MTF) is the indicator most frequently used for image resolution assessment. Traditionally in photogrammetry, the MTF is directly estimated using specifically designed targets such as the USAF 1952 three-bar resolution test target, but it can also be indirectly derived from the system degradation function known as the point-spread function (PSF). Theoretically, MTF and PSF are related through a spatial–frequency domain transformation (a Fourier transformation), meaning the same attributes are expressed in different domains. When using real images, however, it is not clear whether these two functions produce the same result. In this study, both spatial and frequency domain approaches were experimentally compared through simulations. Results show that the MTF derived from the PSF has better accuracy than an MTF estimated directly from the resolution target.
