Abstract

The embodiment of the present invention provides a data extraction method and device. The method includes: after obtaining the first type of data extraction instruction, obtaining the data extraction condition set in the corresponding preset storage space, wherein the data extraction condition is: used for filtering In addition to the condition of invalid passing data; from the data to be audited stored in the first storage device, the data to be audited that meets the data extraction conditions are obtained as the first data to be audited; the obtained first data to be audited is stored in In the default storage space, so that the reviewer can extract the data from the default storage space. The embodiments of the present invention are applied to filter out invalid passing data, reduce the workload of auditors to a certain extent, and improve the audit efficiency of auditors.

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...
