About the output results of linemap about limap HOT 3 CLOSED

Hi, thanks for the interest!

You can directly read all the information in Python. The output is a list of LineTrack. And the attributes can be accessed directly with, for example, track.image_id_list. Full members are listed here: https://github.com/cvg/limap/blob/main/limap/base/bindings.cc#L231-L259, and documentation will be online soon.

Thanks!

The first line is the number of 3D line segments in the line map.
The second line is the 3D segment ID, which corresponds to the number of 2D segments and 2D images.
The third line is the starting point coordinates of the 3D line segment (X1, Y1, Z1).
The endpoint coordinates of the 3D line segment in the fourth row (X2, Y2, Z2).
The fifth line is the image ID corresponding to these 188 2D line segments.
The sixth line is the 2D segment ID in the image ID corresponding to the previous line one by one.

Is my explanation correct?
