Automatic distance calculation

[ekbmuts]

This might seem like a stupid question but:

If I have known distances between markers in my project, can Photoscan calculate distances between markers for which I do NOT have a known dimension.

Example:  I shot a room with a desk and a window.  I know the exact dimensions of both desk and window.  I place markers accordingly, telling Photoscan coordinates and distances that I have measured in the field on both the desk and the window.  So I have 4 markers on my desk and 3 on my window.  Photoscan tells me that my error once all measurements are input is 0.018656 meters.  Fine.  I can live with that.  I'm not doing rocket science.

But I want to know how far it is from one of the markers on my desk to one of my markers on the window.  So I select both markers in the Workspace menu and create a scale bar.  The scale bar shows up but of course, there's no distance entered because I don't know the distance. 

Can Photoscan calculate that distance for me?

And if so, how?

And if not, wouldn't that be a useful feature to have?

I'm positive that it can.  I just don't know how to do it.

Thanks in advance.

Hello Jon,

In the latest version of 1.2.5 you can also use Ruler tool for quick measurements.

Nice!  I don't see that in 1.2.4 so it must be totally new.
