When a user needs to charge, a charging request can be sent to a server through a request end, and the server can send a first acquisition instruction to a corresponding camera end at a charging pile after receiving the charging request sent by the request end.

After receiving the first acquisition instruction, the camera end responds to the first acquisition instruction to acquire video and takes the moment of receiving the first acquisition instruction as the initial acquisition moment. It can be understood that at this time, the image capturing end starts data acquisition.

S2, after receiving a charging start signal sent by the charging pile, the server synchronizes to the camera end to send a second acquisition instruction, and the camera end responds to the second acquisition instruction to perform video acquisition and identification and takes the moment of receiving the second acquisition instruction as an identification acquisition moment.

It is worth mentioning that the initial collection time is not yet subjected to the charging operation, and when the user inserts the charging gun into the electric automobile, the charging pile can generate a charging start signal.

After receiving a charging start signal sent by the charging pile, the server synchronizes to the camera end to send a second acquisition instruction.

At the moment, the camera end responds to the second acquisition instruction to carry out video acquisition and identification, and the moment of receiving the second acquisition instruction is taken as the identification acquisition moment.

It is understood that the time of recognition acquisition refers to the time when real-time recognition analysis is required for the acquired data, which is different from the time of initial acquisition.

And S3, determining a recognition monitoring area by the camera end according to the video acquired by the position of the charging pile at the second acquisition time, if the recognition monitoring area is judged to have a corresponding recognition target, transmitting the recognition target to the server, and taking the corresponding time as a reminding acquisition time.

Because one camera end corresponds to each monitoring area, the area determination is needed first in the scheme. The camera shooting end can confirm and identify the monitoring area according to the video acquired by the position of the charging pile at the second acquisition time.

If the identification monitoring area is judged to have the corresponding identification target, the identification target is sent to the server, and the corresponding time is used as the reminding acquisition time.

In the above embodiment, if it is determined that the identification monitoring area has the corresponding identification target, the identification target is sent to the server, and the corresponding time is used as the reminding acquisition time, including:

the image in the identification monitoring area is acquired, and an identification target is determined based on OPENCV identification, wherein the identification target at least comprises a person. It will be appreciated that the above-described object recognition may take part in the prior art and will not be described in detail. The OPENCV technology is a target recognition technology commonly used in the prior art, and the determination of the target can be performed by recognizing the outline of the target, which will not be described in detail.

In some cases, if a person exists in the identification monitoring area or the outline of the person is judged to be smaller than the preset distance from the outline of the vehicle, it is indicated that an abnormal condition may exist, at this time, the corresponding identification target is sent to the server, and the server takes the time of receiving the identification target as the reminding acquisition time.

It is worth mentioning that the reminding collection time is the time for indicating the abnormal situation and is used for striking reminding.

In some embodiments, S3 (the camera end determines the identification monitoring area in the video acquired at the second acquisition time according to the position of the charging pile, if it is determined that the identification monitoring area has a corresponding identification target, the identification target is sent to the server, and the corresponding time is used as the reminding acquisition time) includes S31-S33:

The edge computing gateway can determine a corresponding preset camera by combining the position of the charging pile, and then determine that a video acquired by the camera is a target pixel point with a first preset pixel value to obtain a plurality of recognition contour ranges. It can be understood that each charging area generally has a marking line, for example, a white square marking line, and the target pixel point of the first preset pixel value at this time may be a pixel point corresponding to white.
