Hello Albert,

In the previous version geometry merging procedure produced low quality geometry irrespectively to the quality used in original chunks. In the version 1.0.0 you can merge chunks without geometry and build mesh in the merged chunk already.

1. In 1.0.0, I can merge chunks without geometry, but lost the dense point cloud, which is calculated in each chunk. I want to do like this way: in each chunk, calculate camera pos, sparse point, and dense points, then edit the dense point. After that, align and merge the dense point to a new chunk, finally get mesh based this dense point. Now I just can do this: calculate the cam pos and sparse point, then merge them, next calculate dense point, and mesh. This is bad for me, because in my app, some photos are global zoom out, (whole body) some are detailed zoom in (face). The zoom out photo will destroy the detailed photo.

If we merge two chunks (with dense pont, without mesh), that is not good to lost the dense point.

2. I see, in last version, if merge the mesh, will lost some quality, but can get a whole closed model, this is very important I think. In the new combined version, as I said before, if can combine the dense point, that is also good, but now only can combine the sparse point or mesh, for the mesh, it is not closed model, with several layer, this is really bad, I need to do a lot work to edit it. Why not give two possibility here, for some users, like me, we still need.  :)

And thanks for your feedback.

Nice work AGISOFT Team on BETA-version 1.0.

Will there be a funtion in 1.0 to import a Dense Cloud in .las format ?
(which has been classified in an external Software)
Or can you give me a little hint , for a work around?

It would be nice to classify the Dense Point Cloud in an external Software aswell.
Or even if i erase some Dense Cloud Point unintentionally, i can restore them from an backup file (inclusive the classification), without creating the Dense point cloud again, and the classification.
Saving and loading of an whole big Project in PS takes too much time.
Maybe a "save-classification-mask" of Dense Point Cloud could be of a little help.

thx a lot.

delighted by this version
see attached:
all surfaces
ground
Almost like a LIDAR (not exactly but still very good move towards)
Please-please guys - resolve the ghost effect

Cheers

Hello Albert,

After merging two chunks you can re-build dense point cloud in the Merged Chunk and generate mesh based on this data. Also it's possible to create mesh based on sparse point cloud.


Hello 3DFranz,

We are planning import dense point cloud feature.

Hi,

If I re-build the dense point cloudin the merged chunk, will lost a lot of good detail information, and this detail surface can be got in each chunk separated. If the software can combine the dense point cloud, not simple sparse point cloud, that's perfect for me.
Or keep the merged tool in the last version. Thanks.

Hello Albert,

We'll try to implement dense point cloud merging soon.

Hi,
I've started processing some projects that were originally aligned and mesh built in 0.9.1.  I achieved a mesh of 100,000,000 triangles from over 1300 photos, but there was a tiny error in a small portion of the mesh.  Because 1.0.0 was released around then, I decided to reprocess using the dense point cloud and then mesh build with the same triangle count.  I used the same computer (and tried it on two others as well) and found that the 1.0.0 pro version ran out of memory for every build I attempted.  Even when I reduced mesh resolution count to 2/3 the original model.  Any chance you could tell me if I'm doing something wrong?  I really like the other features of the pre-release and would like to keep using it if I can get it to build to the same resolution I'm accustom to from the previous version.
Thank you!

Hello ksimon,

What quality for depth maps was used in 0.9.1 and in 1.0.0? Are you sure you've used the same parameter in both cases?
Probably you can also provide the cpoy of log file for mesh generation step.

Hey guys,

I'm evaluating PS Pro for orthophoto generation of forests and fields of crop-like vegetation. I've successfully rendered 3 orthophotos from 700-2700 15Mpix images (50-100ha), each in under 2-3 non-stop PC work-days. I started a fourth project from 2600 photos with this new version of PS. "Align photos" finished within a reasonable amount of time, then I chose a new step "Build dense point cloud". First phase of this step took about ~30h, and now "Generating dense point cloud..." estimates ~310h left. Since I'm quite a noob in this area, I dare to ask: can I skip this step, and move right to "Build mesh" as I'm used to? If I do so, what do I loose, and what do I gain, in terms of processing time and quality? I know I can just try to, but I'll loose those 30h of previous rendering and I have no other machine to try it on in parallel.

Thanks in advance for your input.

P.S. I don't do manual modification of intermediate results, nor I intend to.
P.S.S. My machine is i7@3.8GHz, 16MB RAM, GeForce GTX 660.

Unfortunately, this version is not stable.
In the final seconds of mesh generation. (Dense cloud)
The demand for memory.
Follows the jump by 200% and
And the work goes to waste.
A few projects I crashed in the final seconds.

small project 240 photos. Saving the project takes 14 minutes.
Is that a joke?
Does anyone sees any advantages of this version?

Dense cloud, less stable.
The inferior quality, fade detail, lack of details in the model.
The only progress is a multi textures.


ps.
Where can I download older versions?
