Abstract

The invention provides a point cloud data storage method and device, a storage medium and electronic equipment. The original point cloud coordinate data is subjected to thinning treatment to obtain to-be-stored coordinate data, which is used for reducing the total amount of point cloud coordinate data; in order to avoid using any two groups of very close original point cloud coordinate data as to-be-stored coordinate data and avoid similar repeated data, it needs to be ensured that any two pieces of to-be-stored coordinate data correspond to different unique identifiers respectively; and under the condition that the data amount is reduced, repeated data is avoided, and data diversity is guaranteed as much as possible; finally, the to-be-stored coordinate data is written into the target tile file, wherein the target tile file is a tile file represented by a tile format name corresponding to the to-be-stored coordinate data. According to the present invention, the data volume in each tile file is further reduced, so that the transmission, storage, retrieval and application visualization of the tile data are facilitated, the requirement for hardware cost is reduced, and harsh transmission and application scenes can be dealt with.

Description

technical field [0001] The present application relates to the field of point cloud data, in particular, to a point cloud data storage method, device, storage medium and electronic equipment. Background technique [0002] With the development of society and the progress of science, point cloud data is widely used in people's work and life. The current way to obtain point cloud data is to use aerial photogrammetry, and then restore the data obtained by measurement to obtain point cloud data. If the point cloud data obtained in this way is stored in a single file, because of the large amount of data, it is not convenient for local retrieval and application visualization, and its transmission and data storage are difficult. Contents of the invention [0003] The purpose of the present application is to provide a point cloud data storage method, device, storage medium and electronic equipment, so as to at least partially improve the above problems. [0004] In order to achiev...
