Abstract

The embodiment of the invention is suitable for the technical field of data processing, and provides a data compression method and device, terminal equipment and a storage medium, and the method comprises the steps: collecting multi-beam data, and generating a grid map according to the multi-beam data, wherein the grid map comprises a plurality of grid points; calculating the depth value of each grid point, and dividing the grid map into a plurality of pixels according to the depth value of each grid point, wherein the grid depth values of the grids contained in the same pixel are the same; determining coded data of each pixel, wherein the coded data comprises a grid depth value of each grid in the pixel; merging the pixels with the same grid depth value to obtain a plurality of data blocks; and determining target coded data of each data block to complete compression of the multi-beam data. By adopting the method, lossless compression of the multi-beam data can be realized.

Description

technical field [0001] The present application belongs to the technical field of data processing, and in particular relates to a data compression method, device, terminal equipment and storage medium. Background technique [0002] The development of unmanned technology has brought new development opportunities to ocean surveying and mapping. By carrying the multi-beam bathymetry system on unmanned boats, the efficiency of ocean exploration can be effectively improved. [0003] The multi-beam bathymetry system is an efficient and high-precision underwater topographic measurement system. When multi-boats cooperate to carry out multi-beam bathymetry system for seabed topographic measurement, real-time data transmission is conducive to the smooth progress of the measurement work, and it is convenient to understand the data collection situation, whether there is an uninvolved area to be measured, etc. The amount of data collected by the multi-beam bathymetry system is very large...
