dcterms.abstractA three-dimensional affine transformation method employs ALBTM (a three-dimensional affine model based on line feature) to express the relationship between two-dimensional space and three-dimensional space, and the specific mathematical expression of ALBTM is Sax=C1AX+C2AY+C3AZ, Say=C5AX+C6AY+C7AZ, wherein the (ax, ay) are unit vector components of a line-segment in two-dimensional space, the (AX, AY, AZ) are unit vector components corresponding to a conjugate line segment of the line-segment in the three-dimensional space, the S is the proportional divisor of the line-segment and the conjugate line segment, the C1-C3 and C5-C7 are rotary parameters of the ALBTM. Disclosed also is geometry correction method of satellite remote sensing images, which includes step 1 obtaining at least two satellite remote sensing images data, step 2 respectively computing the model parameter for three-dimensional affine transformation of image space and terrain space of each satellite remote image on the basis of the image data and by the three-dimensional affine transformation method, step 3 defining the coordinate of center point of the image space in the terrain space according to the model parameter.-
