markers automatic measurement

Hello,

Hello, I work for an archaeological company where we often take hundreds
 of photos per week that we process with photoshop. 
Unfortunately unless I'm mistaken there is no option to photograph markers
 that are recognized by photoshop. Now we use a size bar and a digital size 
bar where we adjust the photo on the size bar. This would be a nice feature.

Maybe an idea to add this... 

Check out metashape (agisoft) what I mean with markers.
