The dictionary-related operations are as follows: inserting elements having a given key value, looking for elements having a given key value in the dictionary, deleting elements having a given key value.
In this embodiment, after determining the overlapping area of each remote sensing image to be compared according to the size of the upper layer of image layer expansion, the remote sensing images in the overlapping area may be saved in a dictionary (dictionary) manner, which may facilitate subsequent searching.

Where a pixel is made up of tiles of an image, the tiles have a definite position and assigned color value, and the tile color and position determine how the image appears. The pixel image may be an image consisting of blocks of pixels.
In this embodiment, to compare the differences between the overlapping areas of the remote sensing images to be compared, a pixel matching (pixeltach) method may be used to convert the original remote sensing image in the overlapping area into a pixel image with RGB color standard, and the comparison of the remote sensing images is achieved by comparing the differences between each pixel block.
Optionally, the method for comparing pixel differences between the pixel images to obtain the comparison result may be: determining a first number of target pixel blocks in each pixel image according to the target images to be compared in the overlapping region; and determining a second number of pixel blocks with differences between the target pixel blocks corresponding to each pixel image, and taking the ratio of the second number to the first number as a comparison result.
Specifically, the target image is an image corresponding to a shooting target of the remote sensing image in the overlapping area, and the target pixel block is a pixel block obtained after the target image is converted into the pixel image. For example, when the satellite captures a remote sensing image, and targets the vegetation coverage of the captured land, the target image may be a vegetation image appearing in the overlapping area. When the pixel differences among the pixel images are compared, the target pixel blocks can be extracted and the number of the target pixel blocks can be determined, then the target pixel blocks in the pixel images are compared, and the pixel blocks with the differences are extracted and the number of the target pixel blocks is determined, so that the ratio of the two numbers is the comparison result. In the above example, the obtained ratio is the vegetation change rate in the overlapping area of the two remote sensing images to be compared.
According to the remote sensing image comparison method disclosed by the embodiment of the invention, an intuitive display method for a plurality of remote sensing images is provided for a user through the layer roller shutter, so that the user can know the difference between the images more clearly, and the accuracy of the comparison result is improved through the remote sensing image pixelation method for distinguishing and comparing.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) through which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic input, speech input, or tactile input.
The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.
The computing system may include clients and servers. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.
