It will be greatly helpful to export tie points for each image in ascii file imagename.pts with contents as:
imagename, point id1, x1, y1
imagename, point id2, x2, y2
imagename, point id3, x3, y3
...
and the 3d model points coordinates as:
point id1, X1, Y1, Z1
point id2, X2, Y2, Z2
point id3, X3, Y3, Z3
...
