The NIH's "visible human" project is often used for baseline anatomical reference, so if you just need one value to compare yours to (i.e., verify unit conversions), that would be a good place to check. You can find segmented surfaces of the bony anatomy from biomedtown.org (link below), that you can view (and modify) in the free surface software Datamanager also from biomedtown, where you can make measurements, translations, rotations, etc. Or, you can download the DICOMS from NIH/National Library of Medicine and segment them yourself (free software also available).
If you are looking for a range of human pelvic variability, lots of anthropometric data probably exists, just have to go search for it. Pure anatomical data is usually dated, so it might take a little more effort than a simple Google Scholar search (you might have to go old-school), but it is probably out there.
Good Luck
