How does Colmap perform dense reconstruction with a collection of images captured at different timestamps?

[RaymondLam857]

When using Colmap for reconstruction, images captured at the same location but at different timestamps can vary. How can dense reconstruction be achieved in this case, and will the point cloud models from different time points overlap?
I ran colmap for dense reconstruction and the patterns that were supposed to be in the same position were not reconstructed to the same position. Instead, it was rebuilt to another location.
