La fabrication se faisait jadis soit à la main, soit par impression mécanique ; elle se fait principalement à partir de la fin du XXe siècle par ordinateur et imprimante.

[Termes IGN] système de numérisation mobileRésumé : (Auteur) Mobile mapping systems have been developed to achieve a fast automated acquisition of huge quantity of georeferenced terrestrial images in urban cities. Stereopolis is such a system making it possible to capture panoramic groups of images. These georeferenced photos are then stored in urban images street scale reference databases. The issue investigated in this paper is the problem of tie points extraction between new images captured with an approximate georeferencement by a ”nomad system” and images from the reference database in order to estimate a precise pose for these new images. Because of several difficulties (diachronism, viewpoint change, scale variation, repetitive patterns) extracting enough correct well distributed tie points is difficult and directly extracted and matched SIFT keypoints from original images are most of the time not sufficient. Nevertheless, results can be improved using ortho-rectified images on the facade plane instead of original images. Rectification parameters (3D rotation) are obtained from the coordinates of vanishing points corresponding to the two main directions of the facade. These points can indeed be extracted from linear features of the facade on the images. However, many point matches remain false and difficult to detect using only their image coordinates. The use of both image coordinates and scale and orientation associated to the matched SIFT keypoints makes it possible to detect outliers and to obtain an approximate similitude model between the two ortho-images. A more accurate model can then be computed from correct tie points.

[Termes IGN] transformation de FourierRésumé : (Auteur) This paper presents a simple yet efficient approach for automatic blur detection in aerial images provided by a multi-channel digital camera system. The blur in consideration is due to the airplane motion and causes anisotropy in the Fourier Transform of the image. This anisotropy can be detected and estimated to recover the characteristics of the motion blur, but one cannot disambiguate the anisotropy produced by a motion blur from the possible spectral anisotropy of the underlying sharp image. The proposed approach uses a camera with channel-dependent exposure times to address this issue. Under this multi-exposure setting, the motion blur kernel is scaled proportionally to the exposure-time, whereas the phase differences between the underlying sharp colour channels are assumedly negligible. We show that considering the phase of the ratio of the Fourier Transforms of two channels enhances blur detection. Results obtained on 2000 images confirm the operational efficiency of our method.

[Termes IGN] étalonnage de capteur (imagerie)Résumé : (Auteur) This paper presents a method to calibrate a camera from panoramas. Camera calibration using panoramas has two main advantages: on the one hand it requires neither ground control points or calibration patterns and on the other hand the estimation of intrinsic and distortion parameters is of higher quality due to the loop constraint and to a decorrelation of tied parameters due to the fixed perspective center.
The paper is organised as follow. The first part presents the acquisition process and our mathematical estimation framework. The second part explores with simulated data sets the impact of noisy measures, of geometry of acquisition and of unmodelled parallaxes on the calibration results. A comparison with a traditional calibration method (i.e by using a 3D target network) is then studied. The final section presents results in a real case and compares the results obtained with our panorama approach against the classical calibration. The results are very promising.Numéro de notice : C2010-001 Affiliation des auteurs : MATIS (1993-2011) Thématique : IMAGERIE Nature : Communication nature-HAL : ComAvecCL&ActesPubliésIntl DOI : sans En ligne : https://www.isprs.org/proceedings/XXXVIII/part3/a/pdf/73_XXXVIII-part3A.pdf Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=65056 A procedure for radiometric recalibration of Landsat 5 TM reflective-band data / Gyanesh Chander in IEEE Transactions on geoscience and remote sensing, vol 48 n° 1 Tome 2 (January 2010)

[Termes IGN] traitement différéRésumé : (Auteur) From the Landsat program's inception in 1972 to the present, the Earth science user community has been benefiting from a historical record of remotely sensed data. The multispectral data from the Landsat 5 (L5) Thematic Mapper (TM) sensor provide the backbone for this extensive archive. Historically, the radiometric calibration procedure for the L5 TM imagery used the detectors' response to the internal calibrator (IC) on a scene-by-scene basis to determine the gain and offset for each detector. The IC system degraded with time, causing radiometric calibration errors up to 20%. In May 2003, the L5 TM data processed and distributed by the U.S. Geological Survey (USGS) Earth Resources Observation and Science Center through the National Landsat Archive Production System (NLAPS) were updated to use a lifetime lookup-table (LUT) gain model to radiometrically calibrate TM data instead of using scene-specific IC gains. Further modification of the gain model was performed in 2007. The L5 TM data processed using IC prior to the calibration update do not benefit from the recent calibration revisions. A procedure has been developed to give users the ability to recalibrate their existing level-1 products. The best recalibration results are obtained if the work-order report that was included in the original standard data product delivery is available. However, if users do not have the original work-order report, the IC trends can be used for recalibration. The IC trends were generated using the radiometric gain trends recorded in the NLAPS database. This paper provides the details of the recalibration procedure for the following: 1) data processed using IC where users have the work-order file; 2) data processed using IC where users do not have the work-order file; 3) data processed using prelaunch calibration parameters; and 4) data processed using the previous version of the LUT (e.g., LUT03) that was released before April 2, 2007.
