Method and arrangement for carrying out geodesic measurements utilizes a video tachymeter fitted with an electronic camera using a pixel matrix to determine coordinates of lens points.

摘要

A surface (E) in a lens space of a surface (E') in an image space is coordinated in a surface of a charge coupled device (CCD) matrix (20). An optical axis (50) for a video tachymeter is marked out by a point (P) in the lens space, by a lens principal point (52) in a telescopic lens (53) and by the optical axis' piercing point (P') through the CCD matrix. This piercing point has coordinates in the CCD matrix coordinate system.
