Abstract

The invention is applicable to the technical field of data compression, and provides a mean value calculation method and device based on data compression and terminal equipment. The method comprises the following steps: acquiring a time sequence, filtering the time sequence according to a preset size window to obtain a filtering sequence set, and compressing the time sequence into a semi-continuous segment set; determining a minimum segment set covering the filtering sequence set in the semi-continuous segment set; assigning each time point in the filtering sequence set according to the minimum segment set to obtain a recovery data set, and performing mean value calculation on the recovery data set to obtain a mean value of the time sequence. Mean value calculation is carried out based onthe compressed data, the operation speed is high, the mean value error is controllable, the error condition is met, the mean value quality is ensured, and the execution efficiency is better.

Description

technical field [0001] The invention belongs to the technical field of data compression, and in particular relates to a method, device and terminal equipment for calculating an average value based on data compression. Background technique [0002] The mean is a concept in mathematics, and the arithmetic mean is the most common. In the field of data processing, the mean has a wide range of applications, such as the mean device. At present, most averaging devices are designed on the basis of the original data, that is, the original data is compressed in the early stage to make it convenient for transmission or storage. However, the average value device designed directly based on the compressed data is not visible because of the following two aspects: on the one hand, if the lossless compression algorithm is used for data compression, the compression results are often unexplainable, and it is difficult to compare with the average value. On the other hand, if a lossy compressio...
