Abstract

The invention provides a query method based on big data. The method comprises the following steps: storing an image file into an image library of a distributed file system; preprocessing the image file, and extracting an image characteristic; establishing a characteristic index for the extracted characteristic, and storing an index file and the image file into a distributed file database; and when a user submits a query request to a system, a user interface carries out characteristic extraction on submitted living examples or the image characteristic, carries out similarity comparison with the image characteristic in a characteristic index database and then sends a matching result to the user. The invention provides the query method based on the big data, a storage and retrieval process of the image data is optimized through the distributed system, retrieval efficiency is improved, and performance bottlenecks are overcome.

Description

technical field [0001] The invention relates to big data processing, in particular to a query method based on big data. Background technique [0002] With the vigorous development of the Internet and multimedia technology, image retrieval has gradually become an important way for users to obtain information. Image capacity is generally larger. A large number of image files will be generated in applications in many fields. With the popularization of high-definition, the amount of image data will inevitably increase. Efficient storage and fast and accurate retrieval of massive image data generated in these applications are required. However, the retrieval system of the current B / S architecture has slow retrieval speed and poor concurrency, and will cause performance bottlenecks when image data and index files experience rapid and explosive growth. Contents of the invention [0003] In order to solve the problems in the above-mentioned prior art, the present invention prop...
