According to the concept of "generalized stereopair", this paper focuses on the multi-resource remotely sensed imagery
covering the same regions, and investigates the space intersection mathematics models based on RFM. Considering the
complexity of imagery orientation in generalized stereopairs, this paper expends the original space intersection model
based on RFM, and proposed homologous new models. And then the accuracy of different space intersection models are
analyzed and compared through experiments. The results prove the computing precision and feasibility of space
intersection mathematics models based on generalized stereopairs.
