The invention discloses a heterologous image registration method based on FAST feature extraction and PIIFD feature description. Through FAST feature extraction, PIIFD feature description, nearest neighbor proportion threshold coarse matching, RANSAC mismatching elimination and least square affine transformation calculation, a spatial transformation relation between heterologous images can be obtained. The technical solution of the invention has the advantages of perfect process, high robustness and strong practicability. The method is not easily influenced by the quality of the heterologous image, can overcome the interference of the image background and other factors on feature extraction, and can well solve the problems of low precision, large error, low speed and the like in the registration of the heterologous image at present.
