Image quality can be estimated using "Estimate Image Quality" command from the Photos pane context menu. The quality values range from 0 (blurred images) to 1 (sharp images) and are displayed in the Photos pane in Detailed view.

PhotoScan doesn't use the quality estimates in any way, leaving the user to decide whether to disable blurred photos or not.

The ghosting effect in place of moving objects you noticed is a side effect of a completely new approach for orthophoto generation, which is capable of higher quality outputs than previously used one. We are working on possible solutions to minimize ghosting as much as possible.

Image check is currently performed only during processing steps. Usually the image paths become broken for all photos at once, so it is easy to check this by opening any photo. Of course this will not work if only few image paths are broken.

PhotoScan 1.0.0 distribution was updated to build 1736 today, which fixes major problems reported so far. If previous build didn't work properly for you - please update.

In case there are still any problems, please submit a crash report or post here. All reports are studied very carefully.

Thank you for constructive feedback and for trying latest PhotoScan version.
With best regards,

Here is what I have tested so far. It seems that indeed the buildings are constructed better and the colors are changed but the edges are not so straight as in sharp geometry anymore in some cases.
On the right is the example from the new version done with 1734 build.

Alexey, could be lifted attachment size ? to some "normal" sized images ? say to 500k ?? its pain to rescale images for the forum or uploading to some sharing sites.....

as you can see model reconstruction is much better in almost every situation.

That might be so for aerial photography and reconstruction but there is a drop in quality with multi-camera body scanning, due to dense point cloud integration. Which I have flagged with Agisoft team.

The new mode is great for editing point clouds but the results are softer and we loose details.

Example here:

http://www.ir-ltd.net/uploads/agi-dense01.jpg

http://www.ir-ltd.net/uploads/agi-nodense02.jpg

http://www.ir-ltd.net/uploads/agi-dense02.jpg

This is not ideal as we want to be improving detail, not loosing it.

Hi Infinite. Does the softness really has something to do with the dense point cloud integration? As a matter of fact, from what I've learned, the dense point cloud generation has always been an intermediate step in mesh generation, even in earlier PS versions. The problem is that we weren't able to access to it. Did you check the number of polygons or any other detail that might be responsible for the difference in models? This new workflow is great because we can get much better results with more modest configurations. In my portable, for instance, I was not able to pass "medium" quality meshes and it took ages to render. Now I can get, at least High quality point clouds and the results are a lot, lot better than earlier versions and a lot faster to obtain. It's precisely the opposite of your example - meshes have a lot more detail, sometimes breathtaking, and prominent geometric objects, such as houses and similar objects, are much more similar to the real world. But, as you said, I'm using Heightfield and working with aerial photography. Maybe there are some differences in the Arbitrary option that you are certainly using as preferred option.

Cheers
