I also meet the same question,have you solved the question?

[lyzhenshuai]

When i change the param"USE_GPU" in local_colmap_and_resize.sh,i can get the result.

[enginksz]

Can you specify the change you made , @lyzhenshuai ?

Did you change the value to USE_GPU?

[lyzhenshuai]

i changed the value to 0, did not use the GPU.

Hi, maybe the problem lies with the images themselves; they lack informative details, causing COLMAP to struggle in finding suitable image pairs. Try it with different set of images and check if it works or not.
