The invention relates to a focal plane arc splicing method, which can greatly improves an on-orbit dynamic function transfer of a satellite-borne camera and the registration accuracy among multiple spectrums. In allusion to a focal plane spliced by a plurality of detectors, a direction of arc splicing of the detectors is firstly determined according to the distortion of an optical system, then anangle of arc splicing of the detectors is calculated by using an included angle between an image motion direction and a detector integration direction, and thus the design for arc splicing of the focal plane is completed. Compared with the existing linear splicing technology, the focal plane arc splicing method can solve a problem of reduction in dynamic function transfer brought about by the distortion of the optical system during on-orbit imaging of the satellite-borne camera and the registration accuracy among multiple spectrums, thereby improving the on-orbit imaging quality, and promotingthe development of a larg
