摘要
随着信息社会的发展,日常交互的信息量逐渐增加,数据压缩技术受到了日益广泛的关注。然而传统的数据压缩技术,通常为有损压缩,即在解压后会存在数据丢失的现象,并且在压缩与解压缩的过程中需要损耗大量时间,大大增加了系统运行的资源成本。为了解决上述问题,提出了一种基于IMU模块的无损数据压缩系统,该系统通过数据的独特性、数据的结构以及占用内存三种角度来对IMU数据进行压缩处理。在确保数据解压后仍保持完整性的前提下,通过观察数据的压缩比例以及数据的压缩时间,来选择最佳的数据压缩方式。最终要求数据的压缩比例达到压缩前的三倍,压缩所需的时间不能高于压缩前即为最佳方案。
The traditional data compression technique is usually lossy compression.After decompression,some data is lost,and a lot of time is lost during compression and decompression,which greatly increases the resource cost of system operation in this paper.In order to solve the above problems,a lossless data compression system based on IMU module is proposed in this paper.The system compresses IMU data from three perspectives:data uniqueness,data structure and memory occupancy.The final requirement is that the ratio of data compression should be three times that before compression,and the time required for compression should not be higher than that before compression,which is the best solution.
