Railway external environment potential safety hazard identification method based on remote sensing interpretation library

The invention discloses a railway external environment potential safety hazard identification method based on a remote sensing interpretation library. The method comprises the following steps: S1, formulating an encoding rule of an interpretation library image according to a railway external environment potential safety hazard classification system; s2, taking a single potential safety hazard ground feature as an object, making an on-site shot picture, a satellite image, an aerial photograph and a structure chart of the object, and uniformly naming each reference interpretation chart according to the coding rule in the step S1; s3, establishing an interpretation reference image data selecting a relational database to manage interpretation image related information and item information, including an image information management table and an item information management table, and establishing a connection relationship between the two tables through item coding; s4, interpreting reference image data management;
