Claim One:
1. A method for processing geological information, comprising: acquiring multiple geological image graphs; determining the relation between an image coordinate and a ground coordinate of each of the multiple geological image graphs by an imaging mode of geological images; and joining the multiple geological image graphs together according to the relation between the image coordinate and the ground coordinate of each of the multiple geological image graphs, acquiring first image data and selecting a characteristic point group of a first area on a first image; correcting each characteristic point in the characteristic point group to form a second area wherein correcting each characteristic point comprises; and splicing the second area at a location corresponding to the first area on a second image, wherein correcting each characteristic point comprises: calculating the minimum mean square error of each characteristic point; and correcting each characteristic point according to the minimum mean square error, wherein calculating the minimum mean square error further comprises at least one of: acquiring the minimum mean square error of each characteristic point by performing rigid transformation for the base point coordinate of each characteristic point and the minimum mean square error applies the following formula: min F ⁢ ⁢ E = min F ⁢ 1 N ⁢ ∑ i = 0 N ⁢  y i - F ⁡ ( x i )  2 where x i and y i are the base point coordinates of the characteristic point; min F ⁢ ⁢ E is the minimum mean square error; F(x i ) is rigid transformation, including the distance between any two points in an image that is unchanged before and after the transformation, or, acquiring the minimum mean square error of each characteristic point by performing rotation transformation for the base point coordinate of each characteristic point, and the minimum mean square error applies the following formula: min F ⁢ ⁢ E = 1 N ⁢ ∑ i = 0 N ⁢  y i - R ⁡ ( x i ) - T  2 where x i and y i are the base point coordinates of the characteristic point; min F ⁢ ⁢ E is the minimum mean square error; R(x i ) is rotation transformation including each point P that is enabled to rotate around a fixed point with a fixed angle to become another point P′, the transformation caused thereby is indicating a transformation on a plane; and T is translation transformation including the translation amount between images along the x and y directions.
