Abstract:

Traditional single-view satellite image correction requires some field control points. This paper proposes a satellite image block adjustment method, using the connection points between the images to carry out the forward intersection of the RPC model, and using a small number of control points for affine transformation to realize satellite imagery multi-track multi-view block adjustment. After testing, it can effectively reduce the field control points and improve the ortho rectification efficiency of satellite imagery.

Key words: satellite image, block adjustment, forward intersection, affine transformation, RPC model
