[Termes IGN] valeur aberranteRésumé : (Auteur) A current aim of ongoing research in the field of deformation measurement is to automatically determine geometric changes between several epochs with data captured by terrestrial laser scanners. A critical component within the process chain of deformation measurement is the transformation of captured point clouds into a reference coordinate system. This contribution proposes a surface-based alignment methodology that does not require artificial targets or extracted geometric primitives. A diagnostic method reveals deformations that occurred in between epochs and rejects them from the computation of transformation parameters that would otherwise cause erroneous registrations. The novel approach has been successfully tested on two practical cases where the highest degree of deformation extended to 65% of the total surface area.

In this paper, an automatic methodology for rough georeferencing of large datasets of multiview oblique and vertical aerial images of urban regions without any metadata is proposed. Using feature-based matching combined with robust model fitting and least-squares techniques, the method requires the measurement of a minimum number of points with known coordinates in only one image. The results of this methodology are discussed through the presentation of a developed software suite which identifies the overlapping images, georeferences them, extracts their footprints, subdivides the images into groups based on these footprints and detects the images that cover a specific region.

[Termes IGN] vibrationRésumé : (Auteur) Photogrammetry has been used in the past to monitor the laboratory testing of civil engineering structures using multiple image-based sensors. This has been successful, but detecting vibrations during dynamic structural tests has proved more challenging because they usually depend on high-speed cameras which often results in lower image resolutions and reduced accuracy. To overcome this limitation, a novel approach has been devised to take measurements from blurred images in long-exposure photographs. The motion of the structure is captured in individual motion-blurred images without dependence on imaging speed. A bespoke algorithm then determines each measurement point's motion. Using photogrammetric techniques, a model structure's motion with respect to different excitation frequencies is captured and its vibration envelope recreated in 3D. The approach is tested and used to identify changes in the model's vibration response.

[Termes IGN] interféromètreRésumé : (Auteur) Recently, miniaturised hyperspectral sensors operable from small unmanned airborne vehicle platforms have entered the market. The emerging hyperspectral imaging technologies, based on frame cameras and tuneable filters, are attractive alternatives to hyperspectral pushbroom sensors. This paper addresses the geometric calibration process of a hyperspectral frame camera based on a Fabry–Perot interferometer. However, the addition of more optical elements in front of the image sensor can affect the parameters related to the internal geometry of the camera, and a deficiency in knowledge regarding these parameters can have a critical effect on the accuracy of 3D measurements in photogrammetric applications. The experiments focused on assessing the self-calibrating bundle adjustment to verify the behaviour of the interior parameters, considering different spectral bands. The results indicated that the applied self-calibration method can accurately characterise the interior parameters of this camera and that one set of parameters is required for each internal sensor.

[Termes IGN] test de performanceRésumé : (Auteur) This paper determines the capability of two photogrammetric systems in terms of their measurement uncertainty in an industrial context. The first system–V-STARS INCA3 from Geodetic Systems Inc. – is a commercially available measurement solution. The second system comprises an off-the-shelf Nikon D700 digital camera fitted with a 28 mm Nikkor lens and the research-based Vision Measurement Software (VMS). The uncertainty estimate of these two systems is determined with reference to a calibrated constellation of points determined by a Leica AT401 laser tracker. The calibrated points have an average associated standard uncertainty of 12.4 µm, spanning a maximum distance of approximately 14.5 m. Subsequently, the two systems’ uncertainty was determined. V-STARS INCA3 had an estimated standard uncertainty of 43.1 lm, thus outperforming its manufacturer’s specification; the D700/VMS combination achieved a standard uncertainty of 187 µm.
