Remote sensing image display method and device, storage medium and computer equipment

Abstract

The embodiment of the invention discloses a remote sensing image display method and device, a storage medium and computer equipment. The method comprises steps of when the number of the remote sensingimages corresponding to the target area is greater than a threshold value, dividing the display area into a plurality of grids, and screening out target remote sensing images in one-to-one correspondence with at least part of the grids in the display area from the remote sensing images corresponding to the target area according to the geographic positions of the remote sensing images; and fillinga display area based on the screened target remote sensing image to obtain a display picture. The content of the remote sensing image is not concerned in the process of screening the target remote sensing image; therefore, the content of the remote sensing image does not need to be read; therefore, the remote sensing image does not need to be opened, when the display area is filled, only the target remote sensing image needs to be opened and the image content needs to be read, the times of reading and writing the disk are reduced, the CPU consumption occupied by reading and writing the disk is reduced, the response time of the CPU is shortened, and the display efficiency of the remote sensing image is improved.

Description

technical field [0001] The present application relates to the technical field of remote sensing, and more specifically, to a remote sensing image display method, device, storage medium and computer equipment. Background technique [0002] In the process of remote sensing image processing, there is often such a requirement: to display multiple remote sensing images in a display area of ​​specified length and width. At this time, it is necessary to open the remote sensing image scene by scene, read the content of the remote sensing image and fill it into the display area to generate a display picture. [0003] When the number of remote sensing images to be displayed is small, reading and writing the disk storing the remote sensing images consumes less CPU consumption, does not cause a large impact on the response time of the CPU, and can quickly generate display images. However, when there are a large number of remote sensing images, for example, to display a national 1:5 tho...

Problems solved by technology

However, when there are a large number of remote sensing images, for example, to display a national 1:5 thousand remote sensing image in a 256*256 long and wide display area, it is necessary to open about 4 million remote sensing images to generate a display picture, which requires 400 Wanjing remote sensing images are opened one by one, the image content is read in turn (that is, reading the disk), and the image content is filled into the display area (that is, writing the disk). Reading and writing the disk consumes a lot of CPU and will seriously slow down the response of the CPU. time, making the display efficiency of remote sensing images low
