The invention discloses a multispectral image automatic registration method based on a probe element directional angle model, relates to the technical field of remote sensing image processing, and solves the problem of low registration precision of a local region of an existing multispectral image. Obtaining a control point pair of each image to be registered and the reference image, determining a deviation vector and a registration mode according to the control point pair, fitting the control point pair by adopting a least square fitting method according to the deviation vector, performing distortion correction on a camera load parameter, and resolving a probe element directional angle model of a spectrum band load detector of the images to be registered. And establishing a strict imaging geometric model of the spectrum band. The method has good universality, improves the actual production efficiency of the image, and has a good effect of improving the inter-spectrum registration precision of the single-scen
