关于global_sfm分支application编译中colmap问题

[helloCZZ]

作者你好，我按照你给的global_sfm步骤，已成功完成GraphOptim的编译安装，但是在编译application时遇到colmap版本问题，想请问一下作者使用的是哪个版本的colmap。谢谢。

Hi, the compilation of the global_sfm branch is not thoroughly tested (I only tested it on Ubuntu 20.04), therefore I did not merge it into the main branch. I plan to fix the issue this year (support on more platforms & operating systems). I'd like to help you. Before that, could you show me the compilation output?

问题如下所示：

我对比了不同版本colmap中two_view_geometry.h的代码，发现在3.4及之前为EstimateWithRelativePose，在之后的版本中改为了EstimateRelativePose，如下图所示：


我认为你在application中使用的应该是colmap 3.4之前的版本，我目前也正在尝试更换colmap版本。

okay. Would you mind submitting a PR to fix this issue? For example, we can obtain the version number of COLMAP to use different interfaces.

I'm sorry. I don't know how to do. After I reduced the colmap version to 3.4, a new issue occurred. colmap was only supported as a library after 3.5, but 3.5 uses EstimateRelativePose instead of EstimateWithRelativePose, so when compiling the code in the "application", the colmap library could not be found. I don't know how to solve this problem.

Alright. You may try my branch instead: https://github.com/AIBluefisher/colmap .

Keep this issue opening if the problem is still not solved.

作者您好，我使用了你提供的colmap，能够成功对“application”进行编译，然后按你提供的命令（“./applications/run_global_sfm.sh $DATASET_PATH $OUTPUT_PATH $VOC_TREE_PATH $MOST_SIMILAR_IMAGES_NUM”）运行，运行时出现了以下错误，采用的图片是我自己上传的19张图片，MOST_SIMILAR_IMAGES_NUM设置为5

Could you provide the database or images ?

I have sent it to you via email
