Line track

class limap.base.LineTrack

Associated line track across multi-view.

GetSortedImageIds(self: _limap._base.LineTrack) → List[int]
Returns:

Sorted (and deduplicated) list of the associated image IDs

Return type:

list[int]

HasImage(self: _limap._base.LineTrack, image_id: int) → bool

Check whether the 3D line has a 2D support from a certain image.

Parameters:

image_id (int) – The image ID

Returns:

True if there is a supporting 2D line from this image

Return type:

bool

Read(self: _limap._base.LineTrack, filename: str) → None

Parameters:

filename (str) – The file to read from

Write(self: _limap._base.LineTrack, filename: str) → None

Write the line track information to a file.

Parameters:

filename (str) – The file to write to
