The specific method for consistency matching comprises the following steps:

and respectively carrying out consistency calculation on the preference characteristics of the electricity stealing areas and the preference characteristics of the electricity stealing modes with the area attributes and the category attributes, wherein the consistency calculation formula is as follows:

if the consistency value is lower than the matching threshold value, the matching result is inconsistent;

and if the consistency value is higher than the matching threshold value, the matching result is consistent.

The consistency calculation method also utilizes the Euclidean distance, and can be changed into other similarity calculation formulas in a self-defined mode, such as the Mahalanobis distance and the Manhattan distance.

The consistency of the preference characteristics of the electricity stealing area and the preference characteristics of the electricity stealing mode of the overlapped images and the consistency of the area attributes and the category attributes of the electric energy meter is higher, the electric energy meter conforms to the overlapped images, the electricity stealing accidents of the electric energy meter are large probability events, namely high-risk events, high-degree electricity stealing prevention measures are needed, namely heavy protection is needed, and all the electric energy meters are summarized into an electricity stealing prevention high-risk inspection area.

The consistency of the preference characteristics of the electricity stealing area and the preference characteristics of the electricity stealing mode of the non-overlapped image and the area attributes and category attributes of the electric energy meter is higher, the electric energy meter conforms to the non-overlapped image, the electricity stealing accident of the electric energy meter is a medium and small probability event, namely a low-risk event, the electricity stealing prevention measures with medium and small degrees need to be carried out, namely medium protection needs to be carried out, and all the electric energy meters are summarized into an electricity stealing prevention low-risk inspection area.
