Geometric Accuracy of Ikonos: Zoom In
IEEE Transactions on Geoscience and Remote Sensing, 2004Pioneering in the world, the high-resolution satellite Ikonos imagery has revolutionary changed the market - users now have the unique opportunity to get satellite images with spatial resolution comparable to middle-scale aerial photos. In our study, we tried to find an answer why such images, having submetre spatial resolution, still contain ...

Accuracy of Geometric Estimation
2016We focus here on algebraic methods for ellipse fitting, fundamental matrix computation, and homography computation described in Chaps. 2, 3, and 6 in a more generalized mathematical framework. We do a detailed error analysis in general terms and derive explicit expressions for the covariance and bias of the solution. The hyper-renormalization procedure

The problems of accuracy and robustness in geometric computation
Computer, 1989Practical implementation of geometric operations remains error-prone, and the goal of implementing correct and robust systems for carrying out geometric computation remains elusive. The problem is variously characterized as a matter of achieving sufficient numerical precision, as a fundamental difficulty in dealing with interacting numeric and symbolic

On Geometric Models and Their Accuracy for Extrinsic Sensor Calibration
2018 IEEE International Conference on Robotics and Automation (ICRA), 2018Extrinsic sensor calibration is an important task in robotics. There are various ways to perform the calibration task, but it often remains unclear which methods are better than the others. In this paper, we provide a systematic study about the calibration accuracy of three types of calibration methods, each represented by an abstract geometric model ...

Evaluation of geometric accuracy and the features of TanDEM-X
SPIE Proceedings, 2011The current study evaluated the geometric accuracy of TanDEM-X twice in-situ by simultaneous observations using several corner reflectors. We set the reflectors on the flat ground, and measured the position of the reflectors before and after the satellite pass using GPS and achieved the accuracies within several centimeters.

Geometric accuracy in airborne SAR images
IEEE Transactions on Aerospace and Electronic Systems, 1989Uncorrected across-track motions of a synthetic aperture radar (SAR) platform can cause both a severe loss of azimuthal positioning accuracy in, and defocusing of, the resultant SAR image. It is shown how the results of an autofocus procedure can be incorporated in the azimuth processing to produce a fully focused image that is geometrically accurate ...
