Problems solved by technology

The above problems are concentrated in the image data management layer. The prominent problem is that each system needs to develop a data management model and data storage and storage process separately, so as to adapt to the input data format and meet the data processing requirements of the ground processing system. A large amount of research and development work is concentrated in the The underlying data model is adjusted, and the data management category of the system is poorly scalable. Adding a new data format requires code-level modification by the R&D personnel, and the workload is heavy

Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, it is a flowchart of an image data processing method provided by an embodiment of the present invention, and the method includes the following steps:

[0040] Step S11. A data processing request is received, and the request carries image data to be processed;

[0041] Step S12. According to the system prompt and the data category definition information stored in the system, it is judged whether the data category corresponding to the image data to be processed has been created in the system. If it has not been created, perform step S13; if it has been created, perform step S14;

[0042] Among them, data categories can be classified according to logical characteristics, divided into small data types, standard image types, 1-to-N associated image types, and N-associated product image types; they can also be classified according to data format characteristics, divided into standard formats and independent files Format.

Embodiment 2

[0068] Such as Figure 4 As shown, it is a schematic structural diagram of an image data processing device provided by an embodiment of the present invention. The image data processing device 100 includes: a receiving module 10, a judging module 20, a data category creation module 30, a matching module 40, and a flow customization module 50 and an execution module 60 .

[0069] Wherein, the receiving module 10 is used to receive the data processing request that carries the image data to be processed; the judging module 20 is used to judge whether the data category of the image data to be processed has been created; In the case of creating the data category; the matching module 40 is used for judging by the judging module 20 and judging that the stored data processing flow is reused, or the data processing flow corresponding to the image data to be processed has been customized Next, match the data category; the process customization module 50 is used to determine that the jud...

Abstract

The invention discloses an image data expansion processing method and apparatus. The method comprises the following steps of receiving a data processing request for to-be-processed image data, determining whether a data type for the to-be-processed image data is built, executing a data type building step if the data type is not built, matching the data type and executing a stored data processing process if the data type is built and the stored data processing process can be reused, with data processing resource stored, customizing a data processing data corresponding to the to-be-processed image data based on the stored data processing resources when the data type is built but the stored data processing process cannot be reused, and matching the data type and executing the customized data processing process. With abstractive remote-sensing image types and effective rule collection, a DB dynamic management model is built and a work flow method capable of being expanded can be built; and expansion processing for massive image data can be achieved.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellite data processing, in particular to an SSI (Struts SpringIbatis)-based image data extension processing method and device. Background technique [0002] In recent years, remote sensing satellite data has become a hot topic in the fields of national security, foreign policy, and scientific research on global environmental change.
