Summary:The invention discloses an optimal matching method for geographic vector data and a high-resolution remote sensing image, which comprises the following steps of: acquiring the high-resolution remote sensing image, performing optimal segmentation on the high-resolution remote sensing image, and acquiring geographic vector data in a geographic position range; setting a maximum deviation range of dynamic matching; acquiring position information of external rectangles of data polygons in the geographic vector as a to-be-matched range of an optimal segmentation result, taking the polygons in the range, and judging a matching relationship between the two polygons; traversing all polygons of the geographic vector data in a range needing to be matched in sequence to carry out matching degree analysis; and performing correction of different offsets on the geographic vector data, and obtaining an optimal offset according to an overlapping area ratio of the corrected geographic vector data and the optimal segmentation r
