Differences in volume calculation from photogrammetry

Hi,

Untill today I have always been using Global Mapper to calculate volumes from my photogrammetry measurements.
Since there are a lot of software packages that can do this, I wanted to see the differences in results.
So, I downloaded some other software demo's to make a comparison. To my surprise there is quiet some difference in the results..
I understand that the calculations are not the same. But how can I know which software is the most accurate?

Thanks!

I think the easiest way to determine this is to try using a "test" object, the size of which is known in advance ... and see what different programs show.
