Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] S11: saving multiple image data in a shared storage area;

[0024] S12: Determine the photographic quality level of each image data based on its shooting quality, and determine its product processing level through the image data processing process;

[0025] S13: selecting the image data whose photographic quality level and the product processing level both meet the threshold and store it in the working storage area;

[0026] S14: In the working storage area, if there are a plurality of image data taken multiple times for the same object, then according to the shooting time, photography quality level and product quality level, select the optimal image data and store it in the product storage area;

[0027] S15: In the product storage area, if there are multiple image data taken multiple times for the same object, then select a...

Abstract

The invention provides a quality-oriented migration method and system for big image data. The method comprises the steps as follows: a plurality of image data are saved in a shared memory area; a shooting quality grade is determined according to shooting quality of each image datum, and at the same time, product processing grades are determined according to processing processes of the image data; image data with the shooting quality grades and the product processing grades meeting requirements of threshold values simultaneously are stored in a working memory area; in the working memory area, optimal image data are selected and stored in a product memory area; in the product memory area, the optimal image data are selected and stored; and the image data in the product memory area are used for providing access. The invention provides the quality-oriented migration system for the big image data. For the big data, the processing efficiency during each processing operation is improved.

Description

technical field [0001] The invention relates to the field of data migration, in particular to a quality-oriented massive image data migration method and system. Background technique [0002] Massive data can also be called big data (Big data). In the face of such massive data processing, it usually requires many computers to work at the same time, and operate the massive data in a time far beyond the user's acceptable time. [0003] For example: historical images taken by cameras, images taken by remote sensing satellites, etc. These data accumulate over time, and there will be duplicate data or some invalid data. Some of these data are not retrieved in each visit , some data may never be accessed because it does not meet the requirements. The storage of these image data is very inefficient in subsequent processing. Contents of the invention [0004] The present invention aims to provide a quality-oriented mass image data migration method to solve the above-mentioned pro...
