The invention provides a super-large scale area network construction method and system based on a local connection relation. Because block adjustment of super-large scale optical satellite images relates to a large amount of connection point matching operations; for ensuring the matching efficiency, matching results need to be selected, redundant data is canceled, and meanwhile, connection points is uniformly distributed. The super-large scale area network construction method based on the local connection relation comprises: selecting images one by one based on an area growing method; dividing a currently selected image into a uniform grid; judging whether allocated connection points exist in the grid according to the local connection relation; if the allocated connection points exist in the grid, selecting a next grid to continue the judgment; if the allocated connection points do not exist in the grid, selecting an optimal connection point by distance, and recording the connection point as a connection point between the grid and a grid corresponding to superimposed images. Therefore, at most one connection point exists in each grid; in a repeated point canceling process, connection points are uniformly distributed. The super-large scale area network construction method based on the local connection relation is feasible and efficient, and can achieve expected effects.
