Attitude Refinement for Orbiting Pushbroom Cameras: a Simple Polynomial Fitting Method
This paper describes a simple pushbroom camera model for Earth observation satellites and proposes a new algorithm to refine the orientation parameters of a camera from a set of ground control points. The relative importance of the various orientation parameters is analyzed. On the last generation of high resolution satellites such as Pléiades and WorldView, the attitude angles are shown to be ...
متن کاملCamera Estimation for Orbiting Pushbroom Imaging Systems
Several space-borne cameras use pushbroom scanning to acquire imagery. Traditionally, modeling and analyzing pushbroom sensors has been computationally intensive due to the motion of the orbiting satellite with respect to the rotating earth, and the nonlinearity of the mathematical model involving orbital dynamics. The most time-consuming part of the computation involves mapping a 3-D point to ...

General Electric Corporate R&D 1 River Rd, Schenectady, NY, 12301 Ph: (518)-387-6190, Fax: (518)-387-6845 email : [email protected] Abstract: Modelling and analyzing pushbroom sensors commonly used in satellite imagery is difficult and computationally intensive due to the motion of an orbiting satellite with respect to the rotating earth, and the non-linearity of the mathematical model involving...
متن کاملStereo Matching for Pushbroom Stereo Cameras
A parallel stereo matching algorithm is presented which is mainly thought for the processing of images from pushbroom stereo cameras. The algorithm is designed for non-epipolar geometry, because of disturbances of flight attitude and velocity. Existing epipolar algorithms can give a first estimation of disparities in epipolar (x-) direction, but the recursive algorithm can also start with zero-...
متن کاملA Simple Polynomial for a Simple Transposition
We are used to thinking of polynomials as very special functions, and with good reason when the domain and range are the real numbers or the rational numbers. However, the situation can be counterintuitive over other rings: over finite fields, for example, every function can be represented by a polynomial! It can thus be interesting to look at familiar functions over less familiar rings and fin...
