[Termes IGN] tachéomètre électroniqueIndex. décimale : 30.03 Instruments de géodésie Résumé : (Auteur) A wide range of geodetic measurement methods use tachymetry for technical implementation. The number of robotic-tachymeters with automatic target recognition has increased considerably during the last years. These instruments provide a precise target detection without manual operation by the user and help to accelerate measuring processes due to their automated units.
Différent methods of testing tachymeters have been established during the past years, but not all can be applied to robotic-tachymeters. The increasing automation of measurement processes and the complexity of the measurement systems require new testing approaches, which should not only be component based but should also take into consideration the system performance. Because of this automated tracking function robotic-tachymeters are able to carry out measurements to moving targets. To meet the requirements of robotic-tachymeters the existing testing methods have to be expanded to kinematic situations.
This thesis deals with the functional principles of target recognition and tracking and introduces the requirements for performance ratings. The principles of testing methods which are used in the surveying-related applications are compared to the methods of the ,Physikalisch-Technische Bundesanstalt" (PTB). To express the uncertainties of measurements every single step of the measuring process is represented in a signal-flow-chart. These charts serve as a basis to, show the influence of some components on the results during the measurements. For the description of these uncertainties the ,Guide to the expression of uncertainty in measurement" (GUM) is used.
To examine the behaviour of robotic-tachymeters a testing method using a rotating circular path is introduced. The circular path has been set up in a way to enable extensive analyses providing time-related positions. The setup of the circular path is realised in two différent ways i.e. a horizontal or a vertical rotation level. The results contain the influence of différent measurement categories. A simulation serves to show the influence on the circular path by roughly synchronised measurement categories. The offset of the circular path can be used to calculate the time offset between the measurement categories. The time-related positions can further be used to derive the absolute position offset and to estimate the deviation. As examples two robotic-tachymeters have been examined, i.e. the Trimble 5602 DR200+ and the Zeiss Elta S10. The testings have shown that the absolute position offset turns out to be considerably larger than the offset of the circular path appears to be. The absolute position offset depends on the distance and rotational speed and take place in the range of a few inches. On the other hand the circular offsets are even smaller. The results allow comparisons between the selected set-up as well as between the examined instruments. The horizontal set-up delivers worse results than the vertical set-up. Based on the différent techniques of target recognition and tracking the instruments use, the circular path shows différent performances which serve as performance ratings. The capability of the circular path to supply performance-ratings has been proven.
The thesis concludes that a multitude of testing-approaches of tachymeters can be applied to the new measuring system " robotic-tachymeter ". It is not advisable to use either the component-based or the system-based testing methods only. Both testing-methods, have their own field of operation. The thesis recommends an introduction of rotational checking routines for quality control. Furthermore propositions are made to improve the construction of the circular path to meet the requirements of future instrumental developments.Numéro de notice : 15141 Affiliation des auteurs : non IGN Thématique : POSITIONNEMENT Nature : Monographie Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=55074 Réservation

[Termes IGN] précision de la classificationRésumé : (Auteur) A new technique for predicting missing field boundaries was developed to increase the accuracy of per-field classification. This technique is based on a comparison of within-field modal land-cover proportion and local variance. Analysis was performed on 4-m and 20-m spatial resolution imagery derived from Compact Airborne Spectrographic Imager (CASI) data, to simulate the difference in land-cover classification accuracy between multispectral Ikonos and Satellite Pour l'Observation de ]a Terre (SPOT) High Resolution Visible (HRV) imager. Initially, per-pixel classification was performed, followed by per-field classification. The technique for detecting missing boundaries was then implemented, and per-field classification was carried out a second time using updated field boundary data. Finally, an accuracy assessment was performed. The results demonstrate that classification was significantly more accurate when the missing boundary flag was used, and that simulated Ikonos imagery was considerably more accurate for this purpose than simulated SPOT HRV imagery.
