@jihaoxuanye Please have a look at the INSTRUCTIONS.md file, especially on installing all requirements (including COLMAP).

I don't have it either，could you tell me how to solve it? And i don't have "image-pairs.txt",how to produce it?

Newer versions of Colmap do not have separate executables anymore. Try replacing the call with './colmap/build/src/exe/colmap matches_importer'

Try replacing the call with './colmap/build/src/exe/colmap matches_importer' Thank you,I follow it,you see ,it seems like the 'matches_importer' run nothing,I don't how to create 'image-pair.txt',so i use 'touch image-pair.txt' to create it,and follow the INSTRUCTIONS.md, reports that:

The image-pair.txt file should contain pairs of images for which features should be matched. If it is empty, no features will be matched.

I want to know how to produce image-pair. txt. I have ran the matching-pipeline.,it doesn't produce Image-pair. txt,just 'matches' directory

[tsattler]

It is a text file containing two image names per row (the filenames are defined with respect to the image directory used by Colmap and separated by a white space). See here (under custom matching): https://colmap.github.io/tutorial.html#feature-matching-and-geometric-verification

If you are using your own dataset, you have to create the file yourself.
