Jagged Topology in PS compared to 123d Catch?

[corillion]

I like the flexibility of PS, but I keep getting very jagged topology. I did a comparison scan in both 123d Catch and PS, seen the results attached. Any idea what settings might help me avoid the jaggedness in the PS scan?

What settings did you use in PhotoScan?
How many photos?
 

[corillion]

I used 36 photos fully surrounding the object in a ring shape, taken from level with the object and .5 meters above. I have attached photos of my settings in PhotoScan. The same photos were used in both PhotoScan and 123d Catch.

Polygon count  - set to around 5-7 mil trias and report back

[corillion]

The highest polygon count available to me is 2.3 million (High). I built the point cloud with Super High settings so I'm not sure how to specify more polys for building the mesh. My rebuilt mesh of over 1 million polys still has a ton of noise (image attached).

any other ideas for how to fix this? It is happening on all my scans, not just this one.

Set it to Custom and then use 6-7 million as Wishgranter suggested.

Alternatively you can also use Custom and set it to 0. Then it will generate the mesh with the maximum amount of polygons possible (and you can lower the polycount later)

[corillion]

Thanks for the tip! I did get more detail at 7 million, but the larger noise is still there. Could it be that the problem is in the quality of my source photos, and 123d catch applies some smoothing that PS does not?

[gatsri]

Yes, I think that is it.
the result depends a lot of your input data.

but you can smooth the model in Potoscan as well. You have to do a Python script...
