The latitude and longitude of the observation are used to determine the insertion position of the convergent sequence, rather than the indexs that previously indicated the insertion relationship.
Introduction
Modified the logic for updating on backtracking to ensure that the sequences replaced by online viterbi backtracking are correctly corresponding.
Others
Note: For some cases where the convergence sequence is in the middle, only the candidate points that are consistent with the observations are updated, this step will reduce the accuracy a bit, but it can ensure that the candidate points before and after the update are corresponding to the same.
Example:
The convergent sequence generally corresponds to the original sequence from the first (second) point to the penultimate first (second) point, but there are some cases where the convergent sequence will be made to correspond to the original sequence from the middle (possibly the fifth point), and the ending position is usually not the penultimate first (second) position either (it may be the penultimate fifth point), and in this case we will only update those nodes between the fifth and the penultimate fifth points.
