| Abstract: | The ortho ready standard product of QuickBird satellite image has been widely used.Geometry rectification is one of the key processing when using this data.Six Geometry rectifying methods,such as Polynomial Model,direct linear transformation,rational rectification based on RPC documents,rational rectification based on GCPs,local region rectification,and quadratic rectification are compared according to their rectification accuracy and the characters of arithmetic.As a result,the method of GCPs-based Rationa... |
