I want to use the tool of SfS to refine the DEM obtain from ASP. The camera model is a pinhole, so the tool cannot read the sun's position from the image. When I use the command of "sfs -i run_noCS/out-crop-DEM_fillhole_600.tif --max-iterations 10 -o sfs_test1/run --reflectance-type 0 --smoothness-weight 0.04 --initial-dem-constraint-weight 0.001 -t pinhole 00749_0005_gray_corrected.tif 00749_0005_gray_corrected.tsai" , it reports the error of ''Could not read sun positions from list or from camera model files." How should I fix the problem?
The ASP book explains the option "--sun-position <string>" A file having on each line an image name and three values in double precision specifying the Sun position in ECEF coordinates.
(1)The image is from Mars, so if I want to use the SfS, what is the definition of ECEF? Whether it is the coordinates in the solid system？
(2) If so, What are the specific units of the three parameters input? (m, km, or au?)
The more detail is in my log.
