Image data storage method and apparatus

Abstract

The embodiments of the invention provide an image data storage method and apparatus. The method comprises the steps of acquiring a plurality of images; generating image data according to the images; extracting target image data with a specified resolution from the image data; for the target image data, generating a tile image, wherein the tile image has corresponding image information; and storing the tile image and the corresponding image information. According to the method and the apparatus, the tile images with the corresponding resolutions can be stored according to actual demands, and when the image data is used, the tile images with the corresponding resolutions can be found out according to different usage demands, so that the usage requirements of different fields on the image data with different resolutions are met.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a storage method for image data and a storage device for image data. Background technique [0002] At present, map services have been widely used in people's work and life, for example, road navigation, location search and so on. The map service provider publishes the obtained data on the network, and users can access the map server through a browser or dedicated application software to obtain map data, and then display it on a PC (personal computer, personal computer) or a handheld device. [0003] Usually, the accuracy of the map data provided by the map service provider can reach the meter level at most. Through the map service, users can query the geographical location of streets, shopping malls, and real estate, and can also find all nearby restaurants, schools, banks, parks, etc. , can basically meet people's daily needs. However, in some special fields, fo...

Problems solved by technology

However, in some special fields, for example, in the field of UAV plant protection, due to the limitation of the operating field and in order to ensure the safety of the plant protection UAV, the accuracy of meter-level data is far from enough. Therefore, it is necessary to collect higher precision, Higher resolution map data

[0004] However, map data with higher precision and higher resolution often means a larger amount of data. For example, for high-resolution images, the data size of a single image can even reach several G (gigabyte, gigabytes). section), this amount of data is almost close to the memory of an ordinary personal computer, and it cannot be directly stored and displayed at all.
