However  the single chip array CCD image sensor camera can't meet the need of measuring precision and photogrammetric covering area. In order to obtain large numbers of information and extensive photogrammetric covering area  we must increase field of vision angle and improve photogrammetric covering area. And all these objects can be realized by exterior field of vision assembling photogrammetric camera. Two side work must be done before images  which obtained by exterior field of vision assembling photogrammetric camera  be used in photogrammetry. First  all assembling camera focal plane need be converted to a benchmark coordinate focal plane to realize camera digital assembling. Second  images must be re-sampled and processing. Because of coordinate conversion  two images from different assembling cameras can be established function relation  which a pixel of image from a camera is corresponding to a pixel of another image from different camera. But through this conversion  some pixels maybe extrusion together and other pixels separate on an image area. So interpolation direction finding(IDF) is used to obtain these pixels and realize image re-sampling. In this paper  the structure of exterior field of vision assembling photogrammetric camera is analyzed  and the coordinate conversion method of exterior field of vision assembling photogrammetric camera and image gray re-sampling method also can be discussed. All the works are based to data pretreatment of exterior vision assembling photogrammetric camera.
