Testing device for photogrammetric instrument - has photograph holder and observation optical system with movable mark

摘要

The device has a mark movable with respect to the photograph holder, and a photogrammetrical photo-coordinate measuring device. A drawing device has a recording medium and a drawing head movable over the recording medium. A movement of the photograph holder with respect to the mark causes a corresponding relative movement between the drawing head and the recording medium. The drawing head (6) draws a line on the recording medium (12) which represents the position of the photograph holder with respect to the mark. A picture transmission system superposes an image of the recording medium on the photograph observation optical system of the photogrammetric instrument.
