    Tomographic imaging is a technique for exploration of a cross-section of an inspected object without destruction. In this research, the series of photographs taken around the opaque object under the ambient light is completely served as the projections- the so-called photo-graphic tomography. From the process of tomography, the outcome is the stack of pseudo cross-sectional image. Not the internal of cross section is authentic, but the edge or contour is valid. In this paper, the concept for 3D modeling using photographic tomography was extended to the case where the camera pose can be varied arbitrary. In such case, camera pose is determined using general camera modeling technique. The extracted geometric transform matrix is used to reorient reconstructed data before implementing the traditional tomographic process. The simulation result is very promising. © 2006 IEEE.
