Some of the photogrammetry services or programs became out of free by time. I wanted to share my realy free method for current time:
After taking a series of photos or extracting extracting them from a video with VLC, i edit them by GIMP with or similiar free picture editing applications.
I use MVE at linux envirement. a little script is making the process easier to work. I guess there is way to use it with windows but i didn't try. MVE gives you a mostly cleaned dens point cloud at the end.
Here are the videos of my method:
