Abstract: A system and a method of calibrating a plurality of digital imaging sensors with different modality for image fusion, comprising the steps of calibrating each digital image generated by a corresponding digital imaging sensor with one or more intrinsic parameters; scaling each digital image at a scaling ratio to generate a scaled digital image which has an overlapping region of interest; cross referencing one or more scaled digital images to derive one or more extrinsic parameters; calibrating each digital imaging sensor with the extrinsic parameters; and transforming and rectifying each digital image such that the region of interest of each digital image is coplanar and aligned.
