Robustly handle undistortion failures #58

Closed ahojnnes closed 1 month ago

In rare cases, keypoint undistortion may fail due to numerical issues. In these cases, the keypoint position may contain NaN values. This leads to NaNs in the global positioning problem and leads to a reconstruction failure.
