Vessel Trajectory Similarity Based on Cubic B-spline Interpolation + Time-constrained Hausdorff Algorithm
View through CrossRef
Abstract
The spatio-temporal trajectory data sampling period is large, and the general trajectory similarity is not suitable. This paper proposes a new algorithm, cubic B-spline interpolation + time-constrained Hausdorff algorithm to calculate the trajectory distance. This paper compares the time-constrained Hausdorff algorithm, cubic B-spline interpolation algorithm and cubic B-spline interpolation + time-constrained Hausdorff algorithm. The experimental results show that the cubic B-spline interpolation + time-constrained Hausdorff algorithm is significantly higher than other algorithms in the accuracy of vessel trajectory similarity.
