The exacting demands of Photogrammetry on the radiometric and geometric characteristics of the imaging sensor and all other elements involved in the acquisition of imagery with solid-state sensors, require a detailed analysis of the factors affecting the performance.
This analysis can build on extensive knowledge acquired over the last twenty years for the calibration of film based cameras. For example the modelling of systematic errors introduced by lenses is identical for both systems. Calibration and analysis techniques, such as the bundle adjustment with self-calibration, are important tools. Another source of a great deal of information are applications of solid-state sensors in astronomy. Exacting radiometric requirements have led to the development of specialized sensors, cameras, image acquisition systems, and calibration techniques. These techniques are currently only partially applicable to photogrammetric tasks though. They are tuned to be used with extremely specialized hardware (cameras, image acquisition systems, testing arrangements) which is typically not available for photogrammetric applications. One task of this dissertation was thus to investigate the effects of cameras, signal transmission techniques, and frame grabbers as they are widely available on the market as off-theshelf equipment. The individual components were investigated first, then the combined radiometric and geometric performance of the system was analyzed, and finally the performance of a system for three-dimensional measurements was verified. This in turn required the installation of an image acquisition system with advanced capabilities to perform various comparative investigations, to set up a three-dimensional testfield, and to write a large amount of software for analysis and calibration.
The geometric regularity and the excellent radiometric characteristics of solid-state sensors make them ideal measurement devices. A number of investigations have shown that the regularity of the sensor element spacing is in the order of 11100 of the spacing. The uniformity of response from sensor element to sensor element is 1 % and better for many off-the-shelf cameras. The geometric regularity of the sensor would thus allow to measure positions of targets imaged on such a sensor with a precision of I/100th of the spacing and better. This is actually achieved and surpassed with special sensors in star tracking applications. The mechanical design and the electronics of CCD-cameras are usually not designed for photogrammetric purposes. The mechanical design is often not sufficiently stable, i.e. the assembly of lens, housing and sensor is not rigid. The camera electronics are designed for visual purposes (e.g. surveillance), thus potentially introducing significant degradations due to a number of factors such a low-pass-filters, gamma correction, addition of video signals, to name but a few.
The largest drawback with respect to the radiometric and geometric performance, but an advantage with respect to economy, is the use of standard analog video signals for the transmission of the imagery acquired by solid-state sensors. These standards were developed in the 1950's for broadcasting and are not at all tuned for the requirements of precise measurements. The radiometric and geometric properties of these signals were analyzed, potential drawbacks discussed, as well as methods for determination and compensation and/or elimination of deficiencies investigated and performed.
Frame grabbers are another critical component of the image acquisition system. They must convert the analog transmitted imagery into matrices of numbers, the digital image.
The radiometric and geometric performance of a number of electronic components and of different synchronization techniques of the frame grabber were analyzed. These tests revealed a number of critical issues such as proper DC-restoration, degrading effects of low-pass-filters, deviations from linearity, low level patterns, and the performance of pixel-synchronous sampling as compared to PLL line- synchronization. This allows to separate influences of the frame grabber from those of the camera. The assessment of the effects of the two synchronization techniques, pixel-synchronous sampling and PLL line-synchronization, lead to the detection of a geometric deformation (which can be introduced when composite video signals are used in connection with PLL line-synchronization) and the confirmation of the degrading effects of line-jitter. It was furthermore shown that pixel- synchronous sampling provides a transmission without loss for photogrammetric purposes. The investigation of several radiometric characteristics of the complete system demonstrated some of the insufficiencies of typical off-the-shelf hardware. Potential trouble spots, such as degradations of the radiometric uniformity at the borders of the imagery, were detected. The difficulty of radiometric calibration of the system was addressed.
A test strategy for the assessment of the geometric stability of the system was developed. The effects of the synchronization on the radiometric performance was used to develop test methods to rapidly pinpoint imprecisions of the frame grabber synchronization. The analysis of the repeatability proved that pixel- synchronous frame grabbing provides identical geometric characteristics as digital transmission. The short time repeatability for both digital image transmission as well as pixel-synchronous sampling was shown to be in the order of 0.004 pixel. The analysis of PLL line--synchronization using pixel-synchronous frame grabbing as reference confirmed that line jitter reduces the internal precision in row direction by a factor of six. Disturbances of the PLL line-synchronization, introduced by composite video signals, were shown to lead to geometric deformations reaching 0.3 pixel. The study of warm-up-effects allowed to determine the minimal time required by the system (camera and frame grabber) to reach a steady state. When using pixel-synchronous sampling the major contributing factor to warm-up effects are thermally-induced deformations of the camera body, i.e. the assembly of lens and sensor. The geometric stability of the image acquisition system was verified with a test of over one week duration. It could be shown that for durations of several days a repeatability of well below 1/100th of a pixel can be achieved. Finally the effects of local variations of the illumination andlor of shadows on the position determination with Least-Squares Matching were analyzed. It was empirically demonstrated that gradients of a few per cent can lead to errors in the estimated position of several hundred's of a pixel.
The geometric precision and accuracy of the system was verified with a three-dimensional testfield. The part of the testfield used in the tests spans a volume of 2600 x 2000 x 1100 mm with 162 targets of 20 mm diameter. The position of the targets was determined with a precision of 0.02 to 0.03 mm by theodolite measurements. Two sets of 48 frames were acquired, one with pixel-synchronous sampling and the other with PLL line-synchronization. The relative accuracy attained with the pixel- synchronously grabbed imagery reaches 1 part in 50 000 in object space and is 1/85th of the pixel spacing in the image when using 30 control points were used. This is reduced to 1 part in 46 000 and 1/50th of the pixel spacing with a minimally constrained network. The accuracy attained with the imagery acquired with PLL line- synchronization is only slightly lower. It was thus shown that very high accuracies can be attained with PLL line-synchronization when appropriate modelling of the geometric deformation and a large number of images are used. A comparison of the object coordinates computed with the two data sets indicated a relative accuracy of 1 part in 70 000 and 60 000 for the X and Y axes respectively. The accuracy in image space of the comparison is 1/100th of the pixel spacing. Finally some factors which limit the accuracy and approaches for their elimination are discussed.Numéro de notice : 62708 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Thèse étrangère DOI : 10.3929/ethz-a-000642182 En ligne : http://dx.doi.org/10.3929/ethz-a-000642182 Format de la ressource électronique : URL Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=61113 Réservation

The feasibility of an integrated navigation system for vehicle location applications has been studied. The data handling of such an integrated navigation system is implemented by means of a Kalman filter. The Kalman filter model consists of a dynamic model, which describes the motions of the vehicle, and a measurement model, which relates all kinds of observables to the system. The final result of this implementation is a procedure for the real time estimation of the state (e.g. position, heading and speed) of the dynamic vehicle. Under the assumptions that the mathematical model is valid the Kalman filter produces optimal estimators of the state. Especially the topic of dynamic models for vehicles has been extensively researched. As a result an appropriate dynamic model has been derived. The theory of quality control in geodetic networks, developed by prof. Baarda, is also applicable to the Kalman filter. Quality encompasses precision and reliability. The real time mathematical model validation in integrated navigation systems is known as the DIA-procedure (detection, identification and adaptation). It is important to validate the mathematical model in real time, because the optimality of the estimators is only guaranteed as long as the assumptions in the mathematical model hold. Simulations have been carried out in order to gain insight in the process of designing an optimal filter, optimal in the sense of precision and reliability. The theory of quality control appears to be feasible to operate in vehicle navigation. The navigation system considered in this thesis consists of an arbitrary radio or satellite positioning system (coordinate observables), an (differential) odometer (observable velocity or distance traveled) and a magnetic compass (observable heading). The results of this system may serve as an indication of how to design well a vehicle location system. Note de contenu : 1. INTRODUCTION

Session 1, chaired by Sharon Semanovich and Gary Weil, covers the mature technology of building and structures thermography. Once again an evening workshop is planned, which is always an enlightening two-way technical exchange and usually an open forum for discussing standards, guidelines, and training in this technology. Session 2, chaired by Dick Brooks and Terry Harter, this year reflects the use of thermography in the power generation field, particularly nuclear power. In order to allow attendees to sit in on as many workshops as possible, Session 2 is immediately followed by a Facilities and Utilities Workshop. Session 3, chaired by Elliot Rittenburg, covers process and product monitoring. More and more applications in this area are being developed for monitoring and control. We appreciate the participation of the authors in this area, particularly in light of the often proprietary nature of these applications. Session 4, chaired by Herb Kaplan and Bob Madding, focuses on the very 'vertical' application of electronics and microelectronics. This technology has particularly matured over the past 5 years, and thermosense has played a major role in technology transfer in this area. This session also has an evening workshop where attendees can share and learn about this important application. Session 5, on standards and ethics, chaired by George Baird, was moved this year from the beginning of the conference to the middle in an effort to have maximum attendance on this important topic. Also new this year is a workshop on Problem Solving, which will be led by Bob Madding. It is hoped that attendees will bring to this workshop their problems, difficulties, and experiences dealing with such topics as temperature measurement, spectral response, calibration, or simply making an application work. Session 6, on research and development, chaired by Jan Eklund, has grown every year to the point where it has become the largest session. The diversity of papers to be presented is a window on the commercial applications of thermography in the '90s. Note de contenu : SESSION 1 - BUILDINGS AND STRUCTURES
