Abstract

The algorithm presented assumes a preliminary determination of the elements of inner orientation and bases its mathematical model on the collinearity condition, from which projective equations are derived. Linearisation of condition equations is based on Taylor's expansion, whilst the subsequent solution follows iteration cycles. The method aims to derive composite corrections to image coordinates, with the aid of test field data. Resume L'auteur presente un algorithme ou l'on suppose determines au prealable les elements d'orientation interne. La modelisation mathematique s'appuie sur les conditions de co-linearite et sur les equations qui en resultent en projection. On linearise les equations de conditions en utilisant un developpement en serie de Taylor, et l'on obtient la solution correspondante par iteration. La methode vise a apporter des corrections aux coordonnees images en utilisant les donnees d'un polygone d'essai. Zusammenfassung Bei dem dargestellten Algorithmus wird die vorlaufige Bestimmung der Elemente der inneren Orientierung angenommen, und das mathematische Modell basiert aufder Kollinearitatsgleichung, woraus perspektive Gleichungen abgeleitet werden. Die Linearisierung der Bedingungsgleichungen erfolgt durch Anwendung der Taylor-Reihe, was fur die folgenden Berechnungen einen iterativen Prozess bedingt. Mit der Methode wird angestrebt, Bildkoordinaten mit Hilfe von Testfelddaten zu verbessern.
航空摄影系统标定算法
该算法在初步确定了内方位要素的基础上,建立了共线性条件下的数学模型,并由此导出了射影方程。条件方程的线性化是基于泰勒展开,而后续的解决方案遵循迭代周期。该方法的目的是借助实测数据,对图像坐标进行复合校正。简历L'auteur提出了一种算法,我们假设它决定了方向网络的可选元素。模型化数学适用于共线性条件和投影结果方程。对线性方程的求解条件,采用泰勒级数展开,求出相应的迭代解。该方法采用了一种校正方法,即对图像进行校正。提出了一种基于数学模型的三维几何模型模型,并提出了一种基于数学模型的三维几何模型,用于三维几何模型的三维几何模型。Taylor-Reihe的线性成形模具是一种基于迭代工艺的成形模具。研究方法与实验方法,研究方法与实验方法。

期刊介绍: The Photogrammetric Record is an international journal containing original, independently and rapidly refereed articles that reflect modern advancements in photogrammetry, 3D imaging, computer vision, and other related non-contact fields. All aspects of the measurement workflow are relevant, from sensor characterisation and modelling, data acquisition, processing algorithms and product generation, to novel applications. The journal provides a record of new research which will contribute both to the advancement of photogrammetric knowledge and to the application of techniques in novel ways. It also seeks to stimulate debate though correspondence, and carries reviews of recent literature from the wider geomatics discipline. Relevant topics include, but are not restricted to: - Photogrammetric sensor calibration and characterisation - Laser scanning (lidar) - Image and 3D sensor technology (e.g. range cameras, natural user interface systems) - Photogrammetric aspects of image processing (e.g. radiometric methods, feature extraction, image matching and scene classification) - Mobile mapping and unmanned vehicular systems (UVS; UAVs) - Registration and orientation - Data fusion and integration of 3D and 2D datasets - Point cloud processing - 3D modelling and reconstruction - Algorithms and novel software - Visualisation and virtual reality - Terrain/object modelling and photogrammetric product generation - Geometric sensor models - Databases and structures for imaging and 3D modelling - Standards and best practice for data acquisition and storage - Change detection and monitoring, and sequence analysis
