And S102, comparing the facial image to be recognized with a white list facial image in a preset white list, and judging whether a white list facial image matched with the facial image to be recognized exists or not.
The face images of the people in the white list, namely the face images in the white list, are stored in the preset white list. The white list personnel can be staff in a monitoring scene, and the statistical system cannot count the number of visitors of the white list personnel. The statistical system compares the face image to be recognized with each white list face image through a preset face recognition algorithm, judges whether a white list face image matched with the face image to be recognized exists or not, and namely judges whether the pedestrian corresponding to the face image to be recognized is a white list person or not.
For example, the face image to be recognized and the white list face image are input into a pre-trained neural network for face recognition, and whether the face image to be recognized and the white list face image are matched is judged. Or based on the comparison of the face models, calculating the similarity between the face image to be recognized and the white list face image, and when the similarity is greater than a preset similarity threshold, determining that the face image to be recognized is matched with the white list face image, where the preset similarity threshold may be set according to actual conditions, for example, the preset similarity threshold is 70%, 80%, or 90%.

The statistical system carries out model comparison on the face image to be recognized and each visitor face image through a preset face recognition algorithm, judges whether the visitor face image matched with the face image to be recognized exists or not, and namely judges whether the visitor corresponding to the face image to be recognized appears or not.
For example, a face model of a face image to be recognized and a face model of each visitor face image are established through a convolutional neural network which is subjected to face recognition training in advance, model comparison is carried out on the face model of the face image to be recognized and the face model of each visitor face image, and whether the visitor face image matched with the face image to be recognized exists is judged; or the target detection method based on the image segmentation technology is used for carrying out model comparison on the face image to be recognized and each visitor face image and judging whether the visitor face image matched with the face image to be recognized exists or not; or the target detection method based on the characteristic matching technology is used for carrying out model comparison on the face image to be recognized and each visitor face image, judging whether the visitor face image matched with the face image to be recognized exists or not, and the like.
And S104, if the visitor face image matched with the face image to be recognized does not exist, taking the face image to be recognized as a new visitor face image, and adding the new visitor face image into the visitor list.
And if the visitor face image matched with the face image to be recognized does not exist, the visitor corresponding to the face image to be recognized appears in the current monitoring scene for the first time, and the statistical system takes the face image to be recognized as a new visitor face image and adds the new visitor face image into the visitor list. Optionally, the visitor corresponding to each visitor image in the visitor list corresponds to a unique ID, so as to count the frequency of visitors.
And S105, counting the number of the face images of the visitors in the visitor list to obtain the number of the visitors.
And the counting system counts the number of the face images of the visitors in the visitor list to obtain the visitor identification number. For example, each visitor corresponding to each visitor image corresponds to a unique ID, and the number of the visitor face images can be counted by counting the visitor IDs and the like.
In the embodiment of the invention, the comparison between the image to be recognized and the white list face image eliminates the statistics of white list personnel (such as workers), and when the visitor face image matched with the face image to be recognized does not exist, the face image to be recognized is added into the visitor list, so that the repeated statistics of the same visitor can be prevented, and the accuracy of the visitor number statistics can be improved.
Optionally, after the determining whether there is a visitor face image matching the face image to be recognized, the method further includes:
and if the visitor face image matched with the face image to be recognized exists, updating the appearance information of the visitor face image matched with the face image to be recognized.
The appearance information of the visitor face image may include the number of times of appearance of the visitor corresponding to the visitor face image, the time of appearance of the corresponding visitor, the place of appearance of the corresponding visitor, and the like.
In the embodiment of the invention, the occurrence information of the face image of the visitor is recorded, so that the statistics on the occurrence frequency, time and other information of the visitor is facilitated, and the analysis of potential customers or potential dangerous personnel and the like is facilitated subsequently according to the occurrence information.
Optionally, the method for counting the number of visitors in the embodiment of the present invention further includes:
step one, obtaining visitor query information, wherein the visitor query information comprises an identification of a face image of a visitor to be queried.
The identification of the visitor face image to be queried can be an ID, name or serial number of the visitor face image to be queried and the like. The identification of the face image of the visitor to be inquired can also be a face image, and the face image of the visitor matched with the face image is detected in the visitor list as the face image of the visitor to be inquired through the preset face recognition algorithm.
And step two, acquiring the appearance information of the visitor face image to be inquired according to the identification of the visitor face image to be inquired in the visitor inquiry information.
And step three, displaying the appearance information of the face image of the visitor to be inquired.
In the embodiment of the invention, the appearance information of the face image of the visitor to be inquired is displayed, so that the behavior of the appointed visitor is conveniently analyzed, and the potential client or the potential dangerous personnel and the like are determined.

in the visitor list, the number of all visitor face images in a specified time period is counted to obtain the number of visitors.
The statistical system may count the number of visitors in a specified time period, for example, the statistical system receives a people number query instruction that counts a specified time period identifying the number of visitors to be counted; and the statistical system inquires the number of all visitor face images in each acquisition time within a specified time period in the visitor list, namely the number of visitors.
In the embodiment of the invention, the acquisition time of the face image of each visitor is recorded in the visitor list, so that the number of visitors in a specified time period can be counted.
Optionally, the visitor list further records an acquisition point of each visitor face image;
above-mentioned statistics visitor's face image's quantity in above-mentioned visitor's list obtains visitor's number, includes:
in the visitor list, the number of all visitor face images of which the acquisition time is in a specified time period and the acquisition points are specified acquisition points is counted to obtain the number of visitors.
The acquisition point is an acquisition point for acquiring image data in the monitoring scene, for example, an image acquisition device, such as a camera or a face capture machine, is an acquisition point.
Optionally, the obtaining of the facial image to be recognized in the monitoring scene includes:
acquiring a face image of each pedestrian newly appearing in a monitoring scene;
the early warning system acquires the face images of each pedestrian newly appearing in the monitoring scene through image acquisition equipment such as a camera in the monitoring scene. For example, the early warning system detects newly appearing pedestrians in the monitoring image of the current monitoring scene through a preset recognition algorithm, and extracts face images of the newly appearing pedestrians. The newly appeared pedestrians refer to pedestrians newly entering the monitoring scene, including the pedestrian entering the current monitoring scene for the first time, and also including the pedestrian entering the current monitoring scene again after leaving the current monitoring scene. Optionally, the early warning system may detect a newly-appearing pedestrian only for an image at an entrance or an exit of the monitored scene, so as to save computational resources.
Step two, judging whether each face image accords with a preset recognizable rule;
the preset recognizable rule can be set according to actual conditions, for example, the resolution of the face image is greater than a preset resolution threshold, or whether the score of the face image is greater than a preset score threshold or not is judged. The early warning system carries out face modeling on the face image, scores the modeled face image, and the scoring rule is that the face image is compared with a three-dimensional reference database of the face one by one to obtain parameters such as pupil distance, pitch angle, left and right angles and the like, and the quality score of the face image is obtained according to the parameters. And judging the face image with the score higher than a preset score threshold value, and conforming to a preset recognizable rule. Judging the face image with the score not higher than a preset score threshold value, and not conforming to a preset recognizable rule.
And step three, taking the face image which accords with the recognizable rule as a face image to be recognized.
The early warning system takes the face image which accords with the recognizable rule as the face image to be recognized. And discarding or storing the face image which does not accord with the recognizable rule to a specified position. Optionally, the face images which do not accord with the preset recognizable rules are added into a snapshot library to facilitate subsequent query and analysis.
In the embodiment of the invention, the face image which accords with the recognizable rule is taken as the face image to be recognized, so that the success rate of comparing the subsequent face images to be recognized can be improved.
Optionally, after counting the number of the face images of the visitors in the visitor list to obtain the number of the visitors, the method further includes:
and if the number of the visitors is not less than a preset visitor number threshold value, generating visitor number alarm.
The preset visitor number threshold is set according to actual conditions, for example, when the monitoring scene is a certain exhibition area of a museum, the number of visitors accommodated in the exhibition area is 100, and the preset visitor number threshold is set to 100. And when the counted number of the visitors is not less than a preset visitor number threshold value, the counting system generates a visitor number alarm. So that corresponding operations, such as temporarily closing an entrance of a monitoring scene, etc., are performed according to the visitor number alarm.
In the embodiment of the invention, when the number of visitors is not less than the preset visitor number threshold, the visitor number alarm is generated, so that the management of the visitor number is convenient, and various requirements of users can be met.
Another flow chart of the visitor count counting method according to the embodiment of the present invention is shown in fig. 2.
The method comprises the steps of obtaining images in a monitoring scene through image acquisition equipment, such as a face snapshot machine, detecting faces in the images, extracting face images to perform face modeling after the faces are detected, comparing built face image models with face image models in a maintained white list library one by one, and if matched face images are not found in the white list library, considering people corresponding to the face images as visitors.
Inquiring a visitor list library, comparing the built face image model with the face image models in the visitor list library one by one, if a matched face image is found in the visitor list library, for example, a face image model with similarity larger than 80% exists through model comparison, determining that a corresponding visitor has appeared, and recording the visitor list library, increasing the current appearance time of the visitor, parameters such as monitoring points and the like, wherein the visitor ID corresponds to a plurality of appearance times, and a plurality of monitoring points are used for subsequent retrieval. And if the matched face image is not found in the visitor name list library, adding the established face image into the visitor name list library, allocating a unique ID for the face image, and recording the parameters of the appearance time, the monitoring point, the model and the like of the visitor corresponding to the face image. And returning the number of the recorded people in the current visitor list library, and transmitting the number of the recorded people to the subscriber terminal through an interface or an alarm mode. When the number of people needing to enter is controlled, when the number of people counted in real time reaches a certain number, some limiting measures can be taken to control people flow.
In addition, the visitor list library can also carry out background retrieval, so that each visitor ID in the visitor list library corresponds to a plurality of appearance time and a plurality of appearance monitoring points, for example, the time and the information of a snapshot machine can be obtained by the face snapshot machine at each time, and the visitors can be retrieved according to the time period and the monitoring points. For example, specifying the number of visitors present at monitoring point 1 during 13-17 pm, the number of visitors present at monitoring point 1 during 13-17 pm is obtained by querying the visitor name list library. Optionally, a snapshot of the visitor in a specified time period can be viewed, so that the user can recognize the visitor more quickly and accurately.
The embodiment of the invention utilizes the methods of face detection, face modeling and face model comparison to count the number of visitors in a certain monitoring environment in real time, can realize the post retrieval of a background, and retrieves the number of visitors according to time periods and monitoring points. The main innovation point of the scheme is that people flow in certain areas, such as shopping malls, hospitals and supermarkets, can be accurately identified, internal workers can be filtered, repeat personnel can be filtered, a more accurate visitor number counting method is provided, and business opportunities are excavated or risk pre-control is carried out.
The existing method for counting the number of people is inaccurate, multiple accesses of the same person are not recognized, and under the scenes of hospitals, supermarkets and the like, the accesses of the same person are very frequent, so that how to filter the same person plays a key role in counting the number of strangers. The system can accurately count the number of people in real time, and can also support the retrieval according to time periods and monitoring points, namely, a certain time period is appointed, certain monitoring points are appointed, the number of people who appear at the appointed monitoring points in the time period can be retrieved for counting, and the system is used for the background working personnel to view the number of people counted in more detail.
