Hi!

First of all, thanks for sharing your application with the community. I appreciate that!

On the other hand, I have downloaded the database called "south-building" and the pre-build binary for windows. The thing is that when I load the database and execute the reconstruction, the point cloud is incorrect.
The following image shows the solution that I get (paused).

Do you have any idea why is this happening to me? Do I have to tune the parameters? How?

I will appreciate any help you could provide me,

Thanks,

Jon

Hi,

This is strange and should not happen. No parameter tweaks are needed to run any of the demo datasets.

I suspect that what you are seeing is caused by a graphics problem. Can you share more info about your platform? Did you download the CUDA version but you do not have a CUDA GPU?

Thanks,
Johannes

Yes, it is really strange.

I am using the windows version without CUDA. In addition, my graphic card is an AMD Radeon HD 5450.
Is your code working only for NVIDIA graphic cards or something like this?

Thanks in advance,

Jon

It should work on all GPUs. I use it on my Mac which ships with an AMD GPU...

What Windows version are you running?

I assume it's not a server machine and you have a real display attached to it?

I just create a new project with the database from south-building, its images and run reconstruction :(

Thanks for fast replying!

As far as I see it is a rendering issue, since if I export the pointcloud to meshlab seems to be right!
Any idea?

Thanks!

Sorry for the late response. I remember that I had a similar issue before and it was related to an outdated GPU and/or GPU driver version.

Could you solve the problem in the meantime?

Thanks,
Johannes

I don´t know if I will be able to try it in another pc. I will write you if I solve it!

In the other hand, I am trying to compile the source code in windows but I have some issues:

In serialization.h:

#if _MSC_VER != 1800
BASIC_TYPE_SERIALIZER(unsigned __int64);
#endif
#endif

In host.h:

#  define snprintf _snprintf

and so other linkage errors.

Have you tried building the source code in VS15?

Thanks again for your help!

I build my code with VS2013 but I know someone who has successfully built it with VS2015 a few days ago.

I solved my linking issues (with ceres-solver) and I commented the previous code, which solved all my errors.
However, when I try to compile it the compiler gets out of heap space. It seems that there are some files with too many #include's.
Do you had this issue before? Do you know how to solve it?

I tried with /Zm and disabling multi-core compiler but the error is still there:

fatal error C1060: compiler is out of heap space

Thanks! :)

I have successfully compiled the source code, but I do not understand how it is organized.
The previous error was from colmap_src since I thought it was needed. However, I see that compiling colmap_targets and INSTALL is enough to make the application work.

So, how is your library organized? Is colmap_src needed for something?
I would appreciate if you could explain me how it is organized :)

Thanks in advance!

Hello there,

Reviving an old thread here, but there didn't seem to be a resolution and I'm having the exact same issue with the South Building set.

Looks like this:



Have tried the cuda and no-cuda versions with the same results.

Running Windows 10 Pro, with an AMD FirePro W5100 GPU

Any ideas? Did compiling from scratch help?

Thanks in advance!

Hi there,

can confirm, with my AMD Vega 64 setup I get visually the same result on that dataset.

Any advice would be great, if you need more information about my system I'd be glad to help.

Thanks in advance

Tom
