Problems solved by technology
[0003] In the related technology, the behavior of one person with multiple cards can be identified by analyzing the transmitted signal strength (RSSI) between the personal identification card and the base station. This method is mainly based on Wifi technology. Due to the uncertainty of Wifi signal strength, standing People at the same location may have large differences in signal strength, resulting in low accuracy of this method
It is also possible to identify the multi-card behavior of one person through the combination of face recognition and gravity sensing, but this method can only be used in fixed areas, and continuous monitoring of personnel is not allowed

The present disclosure relates to a method and device for identifying abnormal objects. The method includes: according to the object identification, determining the first data pair in the data set that satisfies the preset condition, wherein the data set includes a plurality of data to be processed, and each data to be processed includes an object identification, an object position, and a time. The first data pair includes two data to be processed with different object identifiers; according to the object identifiers of the first data pairs, a plurality of second data pairs in the data set corresponding to the object identifiers of the first data pairs are determined ; Judging whether the object positions of the multiple second data pairs meet the matching condition; when the object positions of the multiple second data pairs meet the matching condition, determine the corresponding object of the first data pair as an abnormal object. The embodiments of the present disclosure can quickly and accurately identify abnormal objects according to the similarity of object positions, thereby improving the accuracy of identifying abnormal objects.
Description
technical field [0001] The present disclosure relates to the field of computer technology, in particular to a method and device for identifying abnormal objects. Background technique [0002] In some industries or fields, objects performing tasks or work (such as personnel) may need to carry identifications (such as identification cards) in order to locate and identify their identities. For example, in the mining industry, miners must carry an identification card when they go down the mine. The identification card is used for personnel positioning and identification in the mine. The information on the identification card can be used as the basis for miners' attendance. When miners go down to work, there is a behavior of punching cards, that is, one person carries multiple cards to work in the mine. For example, miner A carries his own identification card and the identification card of miner B to go down the mine at the same time. This behavior is an illegal behavior and need...
