A land change map plot evidence automatic investigation method and system

Abstract

The application discloses a kind of land change map spot evidence automatic investigation method and system, it is related to image processing technical field, method includes: collecting spot semantic data, spot geographic context data and the land image data of accompanying position information;Land image data is divided into the image block of corresponding land area less than the minimum spot of custom-defined size, and land image block data is obtained;The application obtains a probability vector by first analyzing the probability corresponding to each image block in spot and each land class label, then obtains the comprehensive score vector of image block by weighted summation of probability vector and a set weight matrix, so that the land class label of spot can be determined by the comprehensive score vector corresponding to each image block in spot, while the interpretability of final output land class label is increased, and the effect of traditional model "non-black or white" judgment is avoided.
