Abstract

The photogrammetrical pick up of an object with the aid of an opto-electronic solid-state surface sensor can be carried out in partial-images over a large image format if the position of the sensor in the image plane is determined by means of a reseau. This can be done by imaging at least one reseau mesh in the sensor image. After measuring the reseau points in the coordinate system of the partial-image and transforming to the nominal values in the system of the reseau, the position of the surface sensor and transformation parameters for all image points within the reseau mesh are obtained. For this purpose, the approximation position of the sensor must be known with sufficient accuracy to be able to determined the number of the reseau mesh as an unambiguous identification of the reseau points.
