一种面向轮廓保持的轨迹数据压缩算法
A contour maintaining oriented trajectory data compression algorithm
摘要
Abstract
In order to solve contour losses and uncontrollability problems in the process of trajectory compression,a contour maintaining oriented trajectory data compression algorithm is proposed.This algorithm uses Euclidean distance threshold and angle threshold to control the trajectory's contour, and compresses trajectory data in a gradually open-window process.The results on real trajectory dataset and a variety of error metrics show that the algorithm can effectively manipulate the contour of trajectory and solve the problem of contour losses in the process of trajectory compression.关键词
