Embodiment

[0029] This embodiment includes: an automatic processing method for remote sensing images based on parallel computing and distributed storage, and the automatic processing method includes:

[0030] When the system detects new image data, the system automatically performs image registration processing according to a unified standard. The execution methods of tasks in the image registration processing include:

[0031] When processing multiple tasks, execute them in parallel with multiple tasks;

[0032] When processing a single task, it is executed according to the parallel processing mode in single task processing.

[0033] Since the parallel computing framework is used to realize the multi-task parallel processing of image processing and the parallel processing in single-task processing, the efficiency of automatic image processing can be improved under the premise of ensuring the processing effect.

[0034] The image registration process includes:

[0035] a. RPC correctio...
