AUTOMATED TRIANGULATION OF LINEAR SCANNER IMAGERY

ABSTRACT In this paper some new methods for determining the sensor orientation of linear scanner images are discussed. The image matching techniques are used for automatic identification, transfer and measurement of the image tie points, which connect all images in the block together. A new and simple sensor model based on direct linear transformation is developed and compared to the conventional model using interior and exterior orientation parameters. The test results with several different kinds of images are demonstrated. They show that a highly automated and sufficiently accurate triangulation system using the introduced methods can make the application of space imagery from linear scanners much more simple and affordable.
