Option to show Camera locations and image overlap on Ortho view
« on: December 15, 2021, 04:16:32 PM »
it would be very useful to be able to show the Camera locations and image overlap on Ortho view like the one that is generated on the Report, it can be used to draw a the ourter boundary seeing the color pattern with the number of overlapping photos, that way we can know with more presicion what are are to be included with the desired overlap for exporting data.

Hello all,

One workaround would be to create a 3dmodel from sparse cloud and use following script https://github.com/agisoft-llc/metashape-scripts/blob/master/src/colorize_model_by_overlap.py to color vertices according to overlap. Then one can easily draw a polygon in model view enclosing the dark blue area (high overlap) as in following:

Also, a script could be developped to build from sparse model an overlap dem (or dom digital overlap model) where elevation corresponds to overlap from 2 to 10 and more... as in 2nd attachement where area within 9 contour (red line) has 9 or more cameras overlapping:

We need something that also works for us lowly 'Standard' users too...
We can't run scripts.

Hello CheeseAndJamSandwich,

I think that as a rough overlap estimation you can generate the mesh model from Low/Lowest quality depth maps and switch to the mesh confidence view mode:
