Embodiment Construction
[0047] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0048] The embodiment of the invention discloses a fast retrieval method for video files, see figure 1 As shown, the method includes:
[0049] S11: Receive the attribute information of the target video file.
[0050] Specifically, the attribute information of the target video file input by the user is received. The attribute information is the information that can retrieve the target video file. It is understandable that the attribute inform...

The invention discloses a rapid retrieval method for video files. The method comprises the steps of receiving attribute information of a target video file; judging whether the target video file corresponding to the attribute information is stored in high-frequency retrieval information or not; if yes, outputting feature information of the target video file, and updating retrieval information of the target video file; if not, utilizing the attribute information for retrieving the target video file in the storage space; if the target video file is retrieved, updating retrieval information of the target video file, and outputting the feature information of the target video file; when the retrieval information of the target video file meets a preset condition, adding the feature information of the target video file into the high-frequency retrieval information. The feature information of the frequently-retrieved video file stored in the high-frequency retrieval information is built, when a user needs the to-be-retrieved target video file, the feature information of the target video file can be directly output after being retrieved from the high-frequency retrieval information, and the video file retrieval time is shortened.
Description
Technical field [0001] The invention relates to the technical field of big data retrieval, in particular to a video file quick retrieval method and system. Background technique [0002] The proportion of valuable data in intelligent transportation is very low, and intelligent transportation data has very strong timeliness, which means that with the continuous collection of intelligent transportation front-end data, not only will there be more and more data, but also The stored data will grow over time, and its own value will gradually decrease or even be overwritten. This also means that in the actual retrieval process of intelligent transportation, the retrieval target data is often the recently stored valuable data with high timeliness. [0003] In the intelligent transportation system retrieval process, the data usually exhibits different characteristics for different traffic scenarios (time periods), and the retrieval frequency of valuable data tends to be relatively high, tha...
