[Termes IGN] télémétrie laser aéroportéRésumé : (Auteur) In the last decade, airborne laser scanning (ALS) systems have become an alternative source for the acquisition of altimeter data. Compared to high resolution orthoimages, one of the main advantages of ALS is the ability of the laser beam to penetrate vegetation and reach the ground underneath. Therefore, 3D point clouds are essential data for computing Digital Terrain Models (DTM) in natural and vegetated areas. DTMs are a key product for many applications such as tree detection, flood modelling, archeology or road detection. Indeed, in forested areas, traditional image-based algorithms for road and pathway detection would partially fail due to their occlusion by the canopy cover. Thus, crucial information for forest management and fire prevention such as road width and slope would be misevaluated.
This paper deals with road and pathway detection in a complex forested mountaneous area and with their geometrical parameter extraction using lidar data. Firstly, a three-step image-based methodology is proposed to detect road regions. Lidar feature orthoimages are first generated. Then, road seeds are both automatically and semi-automatically detected. And, a region growing algorithm is carried out to retrieve the full pathways from the seeds previously detected. Secondly, these pathways are vectorized using morphological tools, smoothed, and discretized. Finally, ID sections within the lidar point cloud are successively generated for each point of the pathways to estimate more accurately road widths in 3D. We also retrieve a precise location of the pathway borders and centers, exported as vector data.Numéro de notice : C2009-006 Affiliation des auteurs : MATIS+Ext (1993-2011) Thématique : FORET/IMAGERIE Nature : Communication nature-HAL : ComAvecCL&ActesPubliésIntl DOI : sans En ligne : https://www.isprs.org/proceedings/XXXVIII/3-W8/papers/242_laserscanning09.pdf Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=65046

[Termes IGN] télémétrie laser terrestreIndex. décimale : 33.80 Lasergrammétrie Résumé : (Editeur) A systematic, in-depth introduction to theories and principles of Light Detection and Ranging (LiDAR) technology is long overdue, as it is the most important geospatial data acquisition technology to be introduced in recent years. An advanced discussion, this text fills the void. Professionals in fields ranging from geology, geography and geoinformatics to physics, transportation, and law enforcement will benefit from this comprehensive discussion of topographic LiDAR principles, systems, data acquisition, and data processing techniques. The book covers ranging and scanning fundamentals, and broad, contemporary analysis of airborne LiDAR systems, as well as those situated on land and in space. The authors present data collection at the signal level in terms of waveforms and their properties; at the system level with regard to calibration and georeferencing; and at the data level to discuss error budget, quality control, and data organization. They devote the bulk of the book to LiDAR data processing and information extraction and elaborate on recent developments in building extraction and reconstruction, highlighting quality and performance evaluations. There is also extensive discussion of the state-of-the-art technological developments used in: filtering algorithms for digital terrain model generation; strip adjustment of data for registration; co-registration of LiDAR data with imagery; forestry inventory; and surveying. Readers get insight into why LiDAR is the effective tool of choice to collect massive volumes of explicit 3-D data with unprecedented accuracy and simplicity. Compiled by leading experts talking about much of their own pioneering work, this book will give researchers, professionals, and senior students novel ideas to supplement their own experience and practices.

[Termes IGN] télémétrie laser aéroportéIndex. décimale : 33.30 Photogrammétrie numérique Résumé : (Auteur) UAVs are unmanned aerial vehicles. Hence, UAV photogrammetry can be understood as a new photogrammetric measurement tool. UAV photogrammetry opens various new applications in the close range domain, combining aerial and terrestrial photogrammetry, but also introduces low-cost alternatives to the classical manned aerial photogrammtery. This thesis deals with the challenging task: "The use of UAV systems as photogrammetric data acquisition platforms " and the work was conducted by the author at IGP at ETH Zurich from 2003 to 2009.
In this work, a new terminology, UAV Photogrammetry, was introduced. UAV Photogrammetry describes photogrammetric measurement platforms, which operate as either remotely controlled, semi-autonomously, or autonomously, all without a pilot sitting in the platform, and the photogrammetric processing of UAV images. The broad definition covers balloons, kites, gliders, airships, rotary and fixed wing UAVs with the capability for photogrammetric data acquisition in manual, semi-automated and automated flight mode. To more clearly define UAVs, a comprehensive literature review on UAVs used in photogrammetry will be given. Using the existing categorizations of UAVs, the outcome of the literature review and our experiments, a new classification for UAVs, with respect on low-cost and high-end systems, the real-time processing capability (based on the integrated sensors and the flight performance, as well as the influence of environmental conditions), was provided. For this work, UAV systems, based on the new classification, will be selected to demonstrate how UAVs can be applied for photogrammetric data acquisition and processing.
In addition to the revised definitions and classifications of UAVs, we have devised a new generic workflow for the photogrammetric UAV flight planning, image acquisition, quality control and data processing. This workflow can specifically be adapted to individual UAV-systems and applications. Thus, specific tools, such as flight planning, are developed. Based on our results, UAV flight control systems and the flight operations were improved and commercial and in-house developed software packages were additionally evaluated for the processing of UAV image data. The proposed workflow allows the combination of office and field work, enabling the first results to be available during the field work for preliminary analysis.
This dissertation also emphasizes the influence of the manual, assisted and autonomous control of the UAV system on the flight performance during the data acquisition, which in turn influences the results and the feasibility of the photogrammetric data processing. Therefore, an autonomous tachymeter tracking of the flight trajectory was performed firstly with an UAV system. A test field for UAVs was then established at the campus Honggerberg at ETH Zurich. This test field enables us to assess the flight performance of various UAV systems. Specifically, an UAV system combined with a light weight laser scanner acquired a DSM over our test field.
Complementary to the developed workflow the accomplished real world application, this work has shown the great potential of using UAVs in photogrammetry and upcoming applications. The focus of our applications was particularly on archaeology and environmental applications, which allowed us to prove our established workflow and to underline the high potential of UAV systems for specific photogrammetric tasks, specifically the use of autonomous operated and stabilized UAV systems. :
• In the frame of the Nasca/Palpa project, the pre-Inca settlement Pinchango Alto (Peru) was documented with our autonomous flying model helicopter. For the first time an accurate and dense elevation model (10cm resolution) of an archaeological site was generated automatically using our in-house developed software. A detailed analysis of the generated data was done using terrestrial laser scanning data. The comparison of both data sets showed that the mean difference between the elevation models was less than 1cm with a standard deviation of 6cm.
• The world heritage Maya site Copan (Honduras) was documented with our system in 2009. The preliminary results, achieved directly after the data acquisition, underlined the expectations and potentials for up-coming
archaeological analysis and investigations.
• The castle Landenberg was documented with 1cm resolution using terrestrial and UAV images.
• In the framework of this dissertation, the rockslide Randa (Switzerland) was documented with LiDAR and image data taken from a manned helicopter. The results from the manned system were compared to the observed data from a UAV for a small part of the rockslide. The elevation model generated from the UAV image data had a substantial higher resolution and showed less occlusions than the LiDAR data. These differences result from the possibility to acquire image data close to the rockslide using an autonomous operated UAV, without endangering human life, and using a specific flight planning tool for UAVs in mountainous areas. This particular application showed also the limitations of existing UAVs in the data acquisition in Alpine areas, due to the high altitudes. However recent developments of new UAV systems are now ready in future work to operate in Alpine areas.
• Using a quadrotor, equipped with a light weight compact camera, it was possible to generate elevation models of a gravel pit at different time periods (February and April). The image data was acquired in the semi-automated and automated mode, allowing an estimation of the volume dug from the pit over time.
• An UAV was used in a study for the evaluation of genetically modified maize (simulated) on conventional maize. High resolution elevation models and orthoimages were produced from two campaigns. The generated spatial data was integrated into a GIS and then used with measures for the out-crossing in maize, to analyse the inclination, height, distance and wind on the influence of cross-pollination in maize.
Finally, based on the experimental results, a new particular workflow for combination of image and LiDAR sensors on one UAV platform was provided.Note de contenu : 1 Introduction
