My Question

I try start dense_slam_gui.py with dataset from here: https://github.com/ylabo0717/iPhone-3D-Reconstruction (hotel room) and get error:

Exception in thread UpdateMain: Traceback (most recent call last): File "/usr/lib/python3.10/threading.py", line 1009, in _bootstrap_inner self.run() File "/usr/lib/python3.10/threading.py", line 946, in run self._target(*self._args, **self._kwargs) File "/home/USERNAME/PycharmProjects/Escan/t_reconstruction_system/dense_slam_gui.py", line 384, in update_main result = self.model.track_frame_to_model( RuntimeError: [Open3D Error] (void open3d::t::pipelines::kernel::DecodeAndSolve6x6(const open3d::core::Tensor&, open3d::core::Tensor&, float&, int&)) /home/tUSERNAME/Open3D/cpp/open3d/t/pipelines/kernel/TransformationConverter.cpp:145: Singular 6x6 linear system detected, tracking failed.

What does this mean and how to solve it?
