[Termes IGN] précision des mesuresRésumé : (Auteur) Despite the relatively high cost of airborne lidar-derived digital elevation models (DEMs), such products are usually presented without a satisfactory associated estimate of accuracy. For the most part, DEM accuracy estimates are typically provided by comparing lidar heights against a finite sample of check point coordinates from an independent source of higher accuracy, supposing a normal distribution of the derived height differences or errors. This paper proposes a new methodology to assess the vertical accuracy of lidar DEMs using confidence intervals constructed from a finite sample of errors computed at check points. A non-parametric approach has been tested where no particular error distribution is assumed, making the proposed methodology especially applicable to non-normal error distributions of the type usually found in DEMs derived from lidar. The performance of the proposed model was experimentally validated using Monte Carlo simulation on 18 vertical error data-sets. Fifteen of these data-sets were computed from original lidar data provided by the International Society for Photogrammetry and Remote Sensing Working Group III/3, using their respective filtered reference data as ground truth. The three remaining data-sets were provided by the Natural Environment Research Council's Airborne Research and Survey Facility lidar system, together with check points acquired using high precision kinematic GPS. The results proved promising, the proposed models reproducing the statistical behaviour of vertical errors of lidar using a favourable number of check points, even in the cases of data-sets with non-normally distributed residuals. This research can therefore be considered as a potentially important step towards improving the quality control of lidar-derived DEMs. Copyright RS&PS + Blackwell Publishing Numéro de notice : A2008-295 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Article DOI : 10.1111/j.1477-9730.2008.00476.x En ligne : https://doi.org/10.1111/j.1477-9730.2008.00476.x Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=29288

[Termes IGN] télémétrie laser terrestreRésumé : (Auteur) The dimensions of building façades and window apertures are usually determined by making direct measurements using tapes and plummets. This approach, however, has a number of drawbacks including the physical risk to which the persons making the measurements are exposed. This paper proposes an indirect approach based on close range photogrammetry that is inexpensive, simple, fast and safe, and which does not require specialist staff or direct ground control measurements. The method is based on taking a picture using a digital camera and measuring the distance to the object using a handheld laser distance meter. Both items of equipment are mounted on a specially designed support that allows the laser distance meter to move independently of the camera.

[Termes IGN] points homologuesRésumé : (Auteur) In the paper the results of the research on the complete automation of the relative orientation of a stereo pair is presented. The theoretical background needed for understanding this topic is described and the results of testing the algorithms with real data are presented. In general, the relative orientation procedure consists of three phases: input data acquisition, computation of relative orientation parameters and estimation of observation errors. In the process of the complete relative orientation automation, the key step is the automation of homologous points acquisition in the stereo area. In the tests presented, the homologous points were acquired with different methods: manually, semiautomatically and fully automatically. The results of the computed relative orientation parameters have been compared. It has been concluded that the automation of the relative orientation procedure is successful and reliable if the control of the observation errors estimation is built into the procedure, and, especially, we get the results faster than with the manual or semi-automated method.

[Termes IGN] utilisation du solRésumé : Auteur) Growing demand for efficient land use above and below the ground motivates the transition of cadastre and land-management systems from traditional two-dimensional systems to three-dimensional ones. This transition is required especially in sprawling urban areas that are turning into megacities. A major concern in realizing the 3D cadastre vision is the development of efficient methods for attaching the third dimension to the existing 2D systems. In this regard, airborne laser technology that offers direct acquisition of dense and accurate 3D data appears to be the optimal means for this objective. Integration of surface data into objects and shapes, however, requires handling discrepancies between both datasets, which in turn can lead to incorrect assignment of height information. We present herein a methodology for fusing airborne laser-scanning-derived data into existing 2D cadastral systems. We demonstrate this integration in urban environments comprising high-rise buildings and open areas. Analysis of the data sources shows the necessity for such transformation, while the results demonstrate the appropriateness of the proposed fusion concept.

[Termes IGN] reconstruction 3DRésumé : (Auteur) Three-dimensional modelling from single images remains an interesting topic of investigation in the research community, even though range sensors are becoming a common alternative for the generation of 3D information. The interest in single-image-based modelling is motivated by a wide spectrum of applications such as cultural heritage, civil engineering, urban planning and even criminology. In this paper a complete new production flowline is presented for modelling based on a single image. The modelling process consists of a series of familiar steps in photogrammetry and computer vision: feature extraction, vanishing point computation, camera self-calibration, 3D reconstruction and dimensional analysis. In particular, the methodology developed for single-image-based modelling takes a scientific approach combining several proven techniques with robust estimators. Finally, in order to demonstrate its capabilities, the reported examples include several real situations applied in different contexts.
