Abstract

The embodiment of the invention provides a data extraction method and device, and the method comprises the steps of obtaining a data extraction condition set corresponding to a preset storage space after obtaining a first type of data extraction instruction, the data extraction condition being a condition for filtering the invalid vehicle passing data; obtaining the to-be-audited data meeting thedata extraction condition from the to-be-audited data stored in the first storage device as the first to-be-audited data; and storing the obtained first to-be-audited data in a preset storage space, so that an auditor extracts the data from the preset storage space. By applying the embodiment of the invention, the invalid vehicle passing data is filtered, the workload of the audit personnel is reduced to a certain extent, and the audit efficiency of the audit personnel is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a data extraction method and device. Background technique [0002] In the field of intelligent transportation, the data analysis system can obtain a large amount of passing data. The above passing data is: the data identified from the image and / or video collected by the image acquisition device, the passing data and the image and / or video There is a corresponding relationship. The above-mentioned passing data may contain: passing data identified by the data analysis system as used to identify illegal vehicles (hereinafter referred to as data to be reviewed), in order to determine whether the data to be reviewed is valid, that is, whether the vehicle identified by the data to be reviewed If there is a real illegal act, the data to be reviewed needs to be reviewed. Because when the data to be audited is confirmed to be valid, subsequent penalties will be impose...
