Abstract Nowadays, distance is usually used to evaluate the error of trajectory compression. These methods can effectively
indicate the level of geometric similarity between the compressed and the raw trajectory, but it ignores the velocity
error in the compression. To fill the gap of these methods, assuming the velocity changes linearly, a mathematical
model called SVE (Time Synchronized Velocity Error) for evaluating compression error is designed, which can
evaluate the velocity error effectively, conveniently and accurately. Based on this model, an innovative algorithm
called SW-MSVE (Minimum Time Synchronized Velocity Error Based on Sliding Window) is proposed, which
can minimize the velocity… More >
