when I typed in the following two commands:
cd G2LTex/bin
./G2LTex ../Data/bloster/textureimages ../Data/bloster/bloster.ply
errors occurred as follows:
./G2LTex: error while loading shared libraries: libG2LTex.so.1: cannot open shared object file: No such file or directory
The associated solution about this problem did not work!Could you please give me some suggestions?

I used Poisson reconstruction for surface reconstruction of point clouds, but when I ran the program using the ply file, it reported the following error.If it completes point cloud loading, it will also report an error during iteration


Can anyone solve this problem? Thank you very much

When running G2LTex, it said that it could not load image header.

How can I fix it?

Thanks for your work of G2LTex.
I am following this work. There is an issue about the data.
Would please tell me what the 12 figures in .cam file means? The first nine figures is the rotation matrix? Or the fourth, eighth, and twelfth figure combine as the translation vector?

I am looking forward for your reply. Thanks for your time.

I am trying to run the executable exactly as written in the Readme, but i get an error as follows:
./G2LTex: error while loading shared libraries: libG2LTex.so.1: cannot open shared object file: No such file or directory
Can you figure it out?
Thanks

Is it possible to run this project with OpenCV version 3. Is there any way to compile the project from scratch with the newer version of OpenCV or do I have to downgrade to OpenCV 2.4 for sure?
Has anybody tried making a build of this project on their own?

Is it possible for you provide the additional makefile or cmake configuration for compilation?

Hi. Thank you for your great work. It's really interesting and helpful.
I am trying to run your program with your test data and I am getting the following error:
num_views:219
982349 total edges.
371352 faces have not been seen by a view.
Saving model... done.

What should I do to make everything work smoothly?

Hi, thanks a lot for your great work! I am trying to run this code on my own recording and encountered the same error mentioned in #16 with

OpenCV Error: Assertion failed (scn == 3 || scn == 4) in cvtColor

I guess this is related to color space conversion in your library. I am wondering whether you enforce the 16bit depth to be saved in some specific shape, e.g. [H, W, C] which must be 3-dimensional even C=1?

Any suggestion will be appreciated! Thanks

Hi, I managed to run G2LTex successfully on my data, but I have a few questions.
I end up with several textured meshes with one or more texture files per mesh, the biggest ones being 1024*1024.

• Is there a way to generate bigger textures, e.g. 2048*2048? Is it a fixed dimension, or does it depend on input data?
• Also, given the atlas computation is part of your method, I suppose it's not possible to provide my own texture atlas?
• My mesh is only partly textured, some small parts are left black (not covered by the atlas maybe?), Do you know what might be causing this?
• Finally, it is not clear to me what the different output meshes are (result_label, G2LTex, and orgTexSelection). Could you provide some explanation? In my case, orgTexSelection gives the best result.

Thank you for your help.

Hi，
When our data is generating cam data, in the process of converting the world coordinate system to the camera coordinate system, each frame is converted for the data of the previous frame. How is the author's cam data generated? We use a TOF camera, and the space distance unit is mm. Yours is m. Will the resulting cam file be affected?

  Thank you very much and look forward to your answer.

@yanqingan Hi,
Thanks for your excellent work. I don't have a linux system. I wonder if I can use this project with a wondows g++ compiler, like in MinGW. I'm new in this field. Will it have some potential errors I need to keep an eye on or any other suggestions?
Thank you.

Thanks for your work of G2LTex.
I am following this work. There is an issue about the data.

Hi,
I run the executable with your data without problems. Now I try with my new data of the same format. I also change certain lines in the 'config.yml'. When I run the executable again, I get the following:
"Failed to open settings file at:
depth fx:0 fy:0 cx:0 cy:0 width:0 height:0
RGB fx:0 fy:0 cx:0 cy:0 width:0 height:0
Global depth:0 RGB:0
Local RGB:0 edge:0 Reg:0
Global Iterations:0 Local Iterations:0"

Is there any place missed to change? Can you help me out?

Thanks :)

Hi,
I took sfm and stereo matching steps to obtain the camera poses and the depth maps. The poses were calculated by openmvg and the depth maps were calculated by colmap. Some textures look really good but in general the result is bad: obvious texture misalignment, textures inconsistency in boundaries (see below). It seems some camera poses were over-modified and so leaves were mapped to building roofs. I think there are some reasons may explain this:
(1) the SSF reconstruction method you mentioned in paper is not fit for depth generated from image-based stereo method. There are still some noise sources from stereo method not handled in this method. So the reconstruction is very noisy.
(2)The original parameter settings mentioned in your paper were not right in my situation, I need to change them.
Anyway, I wanna know if I can further make this project work well on my situation by trying the above things or any other suggestions.
Thank you very much. Forgive me for I am new in this field.
PS: Here is my result, it did pick some high quality texture image than "let there be color" program.

Is the repo executable on Ubuntu 18?
Getting shared library errors on executing the code:
./G2LTex ../Data/bloster/textureimages ../Data/bloster/bloster.ply
Errors:

1. ./G2LTex: error while loading shared libraries: libopencv_core.so.2.4: cannot open shared object file: No such file or directory
2. ./G2LTex: error while loading shared libraries: libG2LTex.so.1: cannot open shared object file: No such file or directory
   Is this due to ubuntu version?

hi,
Sorry to bother again, but I wonder which version suitesparse you use in this project. I configure suitesparse5.1.2 in my system and get a libcholmod.so.3.0.11. Here the cmd points out I should use libcholmod.so.3.0.6:

Thank you~

Hi,

I have an obj file without any texture information. Does anyone know how to convert it to the ply format which is suitable for this project? I tried using blender and meshlab. However, they both tried to add texture information in the created ply file. I am not sure whether this was the reason that crash the program.
I am getting this error:

Hello.

I am trying to exercise with models texturing and I would like to test your implementation of the algorithm.
The quality of the textures G2LTex provides seems quite good (given there are 15 texture atlases).
However, I cannot find the description of the optional arguments (and what arguments the program has) to control the texturing pipeline.

Could you please share the information about the optional arguments, please?
It would greatly help me with my research.

I want to use my own dataset include the mesh file and origin images, of cource I need the 16-bit depth_map. I want to obtain the depth-map from the dense_point_reconstruction stages and save the depth-image of png format in order to serve as the input of your program. How can I output the proper 16-bit png ? And 16 bit means the max depth is 65536 mm, But there may be larger than the max-thresold ....

Which is the final output from this algorithm because, I am getting different colour output on G2LTex_material0000_map_Kd.png

I have been facing this issue while running your code on Ubuntu 20.04.

./G2LTex: error while loading shared libraries: libcholmod.so.3.0.6: cannot open shared object file: No such file or directory

The solutions discussed in the existing issues doesn't help.

Thanks for your work, I have installed libjpeg-dev and libpng12-dev, but it output
"Could not load image header of ../Data/bloster/textureimages/color_00.jpg"
"Cannot determine image format"
when I run the program.
Do you know why this happens ？

Hello,I meeting a problem as follows,I kept all the input formats consistent with the author. I don't know what could be a bug.I am new at it,if you give me some suggesions ,i will be appricate it .
(The example given by the author can run through.)
