Some Advances in the Field Photogrammetry and Digital Image Processing

In this paper, some advances in the use of digital image processing for solving the photogrammetric problems are discussed since professor Wang Zhizhuo's point of view "digital image processing will be a new operational field of photogrammetry". The subjects under discussion include fast differential rectification, image enhancement and digital mosaic, digital stereoorthophotomap, use of ephemeris data and estimation of parameters for LANDSAT and SPOT imagery.
