A method of assembly calibration for a multi-camera system is disclosed. The method comprises receiving at least two images respectively captured by at least two cameras in different angle of views, performing image transformation for aligning the received images which is optional, performing image motion estimation on an overlapping region of the images, for obtaining correspondence between the images with a plurality of motion vectors, wherein the plurality of motion vectors is used for indicating geometry relations between the images, performing dominant vector calculation according to the plurality of motion vectors, to obtain a dominant motion vector in region of interest (ROI) of the overlapping region, and calculating calibration parameters according to the obtained dominant motion vector, performing image correction according to the calibration parameters, to obtain a correct panoramic image covering the whole interested areas.
