Abstract

For the photogrammetric evaluation of digital images, a variety of new methods have been developed in recent years. One of them is the object based least squares matching, which can be applied to frame images as well as to image strips of 3-line cameras. This paper investigates object based least squares matching for the automatic derivation of digital terrain models (DTMs). The investigations were carried out for 3-line image strips, which were taken by the MEOSS camera in 1989 at an altitude of more than 1100 m. The derived DTM is compared with an existing DTM of that region, which was produced manually some years before from frame camera images of lower scale. The overall result is a deviation of 0.6 m between the two DTMs in a test area, which was radiometrically well structured.
