The invention discloses an error control image matching and transmission method based on the constraint of a triangule, which comprises the following procedures: (1) first of all, matching a characteristic dotted pair, the number of which is designated by the user, and starting up the matching and transmission process under a triangular network constraint formed by the characteristic dots; (2) during the matching and transmission process, calculating the priority of a triangular pair, detecting the triangular pairs with wrong matching and reducing the priority of triangular pair; (3) continuing to select a triangle with highest priority, carrying out the matching under triangular constraint, inserting a matching dot into the triangle to update the triangular network and finally acquiring the matched dotted pair with the number designated by the user. The invention has the beneficial effects that: 1) the method can effectively control the matching error in image matching, so as to reduce matching error in final result; 2) the method can hardly be affected by the difference in image content, and; 3) the method can be better applied in detecting the changes of remote sensing image and match the remote sensing image utilized in the detection of changes.
