Abstract

The invention relates to the technical field of computer vision, in particular to an efficient expressway data storage system based on computer vision. The system comprises a data acquisition module used for acquiring perception data and risk data; a trend correlation acquisition module used for acquiring the trend correlation between the lane speed and the lane flow; a road section priority value acquisition module 30 used for acquiring the correlation between the perception data and the risk data and obtaining the priority value of road sections according to the trend correlation and the road bending degree; a road section score acquisition module used for acquiring the score of each road section according to the long-range correlation of the historical perception data, the priority value of the road section and the data access frequency and time of the road section; and a data caching module used for performing data caching according to the score of each road section, and releasing the data with the lowest score of the road section preferentially when the caching space is insufficient. The technical problems of low reading efficiency of important data in the expressway data and low hit rate of the data in the caching space in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a high-efficiency storage system for expressway data based on computer vision. Background technique [0002] With the advancement of science and technology, highway data is growing at the PB level. How to achieve faster and more efficient storage of highway data under a large amount of data is an urgent problem to be solved. [0003] At present, there are some deficiencies in the data storage of existing expressway systems and information architectures. Most of the existing expressway data storage adopts a general-purpose storage architecture, which fails to analyze the characteristics of expressway data, making the reading of important data in expressway data difficult. The retrieval efficiency is low, and the data hit rate in the cache space is low. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the object of the present ...
