Use of this equipment is initially limited to static, quasi-static or stop-and-go techniques. Today, these efficient measuring sensors are used increasingly for kinematic measuring tasks.
Different applications for the precise description of the movement track and for optimizing the horizontal and vertical availability require a combination of these measuring sensors, which operate separately. Normally both these measuring instruments cannot be combined without changing hardware or software (firmware). This thesis presents a method that allows a synchronization of independent measuring systems without a common basis through a comprehensive observation of all factors of disturbance and influence. Calibration of terrestrial and global measuring sensors for kinematic applications is also discussed in detail.
With respect to the description of dynamic movement processes, a calibration of this kind of kinematic measuring sensors requires an expansion of conventional geodetic strategies. Based on static characteristics, these sensors must be tested using kinematic testing methods relating to the type, size and behavior of target points affected by measuring uncertainty. In addition, the real time capability of the measuring system and the synchronization of individual subsystems must be verified and, if required, minimized by corresponding calibration functions.
The result is a hybrid measuring system for kinematic applications that, independent of the type of movement, allows a precise derivation of the movement path based on discrete measuring points on a millimeter scale. For example, these hybrid measuring systems can be employed for the following: 1- as a high precision positioning system for navigation and control of process flows in road and railways track construction (machine guidance), 2- for special applications involving maximum availability and accuracy requirements for land and water vehicles or aircraft, 3- as a reference system to verify the feasible accuracy of positioning and application techniques, and 4- to analyze technical reaction times of partial and overall systems in the precision farming sector.
The descriptions of selected applications in this thesis are limited to testing of section specific land use with the " Landwirtschaftlichen BUS System LBS, (DIN 9684 and ISO 11783) " with respect to position accuracy, precision, quality, and size of disturbances occurring. Investigations have been partly funded by a joint research project within the " Forschungsverbund Agrarökosysteme München, (FAM) " research alliance, which took place at the Chair for Geodesy in cooperation with the Department for Bio Resources and Land Use Technology, Crop Production Engineering (both at the Technical University of Munich).Numéro de notice : 13276 Affiliation des auteurs : non IGN Thématique : POSITIONNEMENT Nature : Thèse étrangère Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=54955 Réservation

[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] positionnement cinématiqueRésumé : (Auteur) The ETRS89 is intented to be a European-wide reference system for all geodetic applications. The EUREF Technical Working Group has initiated a project to establish a Dense European Velocity Field (DEVF) whose main objective is to ensure the long term maintenance of the European Terrestrial Reference Frame 1989 (ETRS89). The DEVF will allow a kinematic instead of somewhat static ETRS89 realization, permitting an accurate positioning in the ETRS89.

[Termes IGN] variable aléatoireRésumé : (Auteur) As an object moves through space, it creates a track (or path) representing the object's past and present position and associated attributes. If data capture falls, then positions along the tracks are unknown. The particular problem we address in this paper is to create tracks of moving objects with missing data. We implement and test two techniques that create continuous tracks of two primate species (Ateles geoffroyi, the red spider monkey, and Cebus capucinus, the whitefaced capuchin). Continuous tracks were needed to calculate home range and to analyze daily ranging patterns for each species. Establishing continuous tracks of primates through field data alone, however, was impossible due to challenging field conditions. The results of the analysis using tracks with interpolated positions helped establish that Ateles tend to move directly to their destination while Cebus tended to follow a more wandering track.
