A data storage method and device and storage medium

Abstract

The embodiment of the invention discloses a data storage method, device and storage medium, which are used to compress the original matrix and improve the utilization rate of storage resources. An embodiment of the present invention provides a data storage method, including: dividing the original matrix into at least two sub-matrices according to the principle of matrix segmentation, the values ​​of the elements in the original matrix before segmentation represent palette data, and The value of the elements in the sub-matrix after division represents the palette data; configure sub-matrix indexes for different sub-matrices in the at least two sub-matrices; according to the position of the sub-matrix in the original matrix The coordinates and the sub-matrix index generate a main matrix, the elements in the main matrix correspond to the position coordinates of the sub-matrix in the original matrix, and the values ​​of the elements in the main matrix represent the corresponding position coordinates Corresponding sub-matrix index; storing the main matrix and different sub-matrices of the at least two sub-matrices into a compressed matrix library.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data storage method and device and a storage medium. Background technique [0002] In a game application, when processing information of different regions, a 32-bit storage space is required to identify the information of a certain location point. Then, the information of all location points is composed into a two-dimensional map matrix of terrain area information, so that the needs of quickly querying area information through location can be met. In game applications, 1024*1024 or even larger maps are often used. For example, in mobile games, a location point of area information is used every 0.5 meters. Such a 1024*1024 map often requires 4 megabytes of memory space to store map information. [0003] In the prior art, information of location points is directly stored as a two-dimensional matrix. The method of directly using two-dimensional matrix storage has the ...

AI Technical Summary

Problems solved by technology

The method of directly using two-dimensional matrix storage has the following disadvantages: it is necessary to apply for a whole block of memory to store two-dimensional matrices, especially for relatively large maps, which require a large block of memory, for example, using one area information per 0.5 meters Location points, when the map is bigger, there are more location points for area information

Therefore, the information storage method provided by the prior art increases the occupation of storage space, and there is a problem of low utilization rate of storage resources
