Is ther any method to get an output of the 3D points?
There isn't an official way to get them, but you may as well know that people have found a way to collect them. Here are a few relevant links.
You may as well know that the easiest way to get your point cloud files is to copy your collection.synth.bin file from the photosynther folder while the last of your photos for that synth are being uploaded to the site. I give more explanation about that in the fourth link above.
For synths that are already uploaded the first three cover what you need to do, but it's definitely more troublesome.
