Embodiment 1
[0054] Please see figure 1 , figure 1 A schematic flowchart of a method for acquiring remote sensing images is provided for the embodiment of the present application. Wherein, the acquisition method of the remote sensing image includes:
[0055] S101. Receive a script code input by a user.
[0056] In this embodiment, the script code may be JavaScript / Python code.
[0057] S102. Compile the script code to obtain an intermediate code.
[0058] In this embodiment, in order to realize the compilation, optimization and distributed execution of the script code, the method proposes a special intermediate code technology. The intermediate code is like a bridge, communicating with the front-end and back-end of the distributed computing nodes. By running the front-end script code, the intermediate code is automatically generated and optimized in real time, and then handed over to the distributed computing nodes for distributed execution, so that the corresponding calculation can b...
Embodiment 2
[0083] Please see figure 2 , figure 2 It is a schematic flowchart of a method for acquiring remote sensing images provided in the embodiment of the present application. Such as figure 2 As shown, wherein, the acquisition method of the remote sensing image includes:
[0084] S201. Perform preprocessing on the acquired original image to obtain a preprocessed image.
[0085] In this embodiment, the acquisition process of the remote sensing sub-image set by the method may be based on an image pyramid index model. That is, the obtained original image is preprocessed by the image pyramid index model to obtain a preprocessed image; the pyramid slice operation is performed on the preprocessed image by the image pyramid index model to obtain a remote sensing sub-image set including at least one remote sensing sub-image.
[0086] In this embodiment, different pre-processed images can be obtained through different pre-processing processes, so as to support real-time data analysis,...
