The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 shows a schematic flow diagram of an identity recognition method provided in an embodiment of the present application, and as shown in fig. 1, the method mainly includes:
step S110: when a first image of a first target position acquired by first image acquisition equipment is received, determining a target user with the intention of moving to a second target position in the first image;
step S120: adding first image identification data corresponding to a target user to a preset first image identification database;
step S130: when a second image is received from a second image capture device at a second target location, the identity of the user in the second image is determined based on the first image recognition database.
The method provided in the embodiment of the application can be applied to a gate system. Taking the gate system as an example, the first target location may be located outside the gate entrance, such as an aisle and a hall outside the gate entrance. The user needs to pass through the first target location before moving to the gate entry location. The first image capturing device may include, but is not limited to, a camera for video recording of the first target location or for capturing of images of the user.
In the embodiment of the application, the target user can be determined through the first image collected at the first target position, specifically, the first image can be analyzed, and whether the user has the intention of brushing the face and entering the gate at the gate entrance is judged. If the fact that the user is the target user with the intention of brushing the face and entering the gate is determined, first image identification data corresponding to the target user can be obtained. In actual use, a plurality of corresponding first image identification data can be acquired according to the characteristics of the target user, and the identification of the target user can be realized based on the first image identification data.
In the embodiment of the application, the preset first image recognition database stores feature information of a user, for example, face feature data. The identification of the user may be performed from the first image recognition database. And adding the first image identification data to a first image identification database, thereby realizing the identification aiming at the target user.
In the embodiment of the application, the second target position can be located in an image acquisition area of a gate entrance, the second image acquisition device can acquire a face image of a user to obtain a second image, and the second image is subjected to face recognition according to the first image recognition database so as to determine the identity of the user.
Whether the user has the intention of swiping the face to enter the gate or not is analyzed according to the first image, so that the first image identification data of the target user with the intention of swiping the face to enter the gate is added to the first image identification database, when a smaller amount of image identification data is preset in the first image identification database, the user can still be identified through the first image identification data supplemented into the first image identification database, and compared with the method for completing the user identification by directly presetting a large amount of data in the first image identification database, the comparison data quantity is smaller, and therefore the identification speed is higher.
According to the method provided by the embodiment of the application, when a first image of a first target position acquired by first image acquisition equipment is received, a target user with the intention of moving to a second target position in the first image is determined, first image identification data corresponding to the target user is added to a preset first image identification database, and when a second image acquired by second image acquisition equipment at a second target position is received, the identity of the user in the second image is determined based on the first image identification database. In the scheme, the first image identification data of the target user is added to the first image identification database, so that the first image identification database has higher pertinence when the user in the second image is identified, the comparison amount of the characteristic data is less, the identification speed can be improved, and the use requirements under the scene with larger pedestrian volume are met.
In an optional manner of the embodiment of the present application, determining a target user having an intention to move to the second target position in the first image includes:
identifying a user to be selected in the first image and user characteristic information of the user to be selected;
and determining a target user with the intention of moving to the second target position from the candidate users based on the user characteristic information.
In the embodiment of the application, the user characteristic information of the user to be selected in the first image can be identified, and the user characteristic information can reflect the intention of the user to a certain extent, so that the user characteristic information can be used for determining the target user.
Specifically, the user characteristic information includes at least one of:
image information of the user's clothing;
the image information of the luggage carried by the user;
behavior information of the user.
As an example, when the user characteristic information is image information of a user's clothing, the target user may be determined by recognizing a specific clothing, for example, when it is recognized that the user's clothing is a specific uniform, it may be considered that the user is likely a worker and has an intention to enter a gate.
As an example, the user characteristic information is image information of baggage carried, the baggage carried by the user may be identified, for example, at a station, etc., and if it is identified that the user carries a large amount of baggage, it may be inferred that the client is a passenger, and may have an intention to enter a gate.
As an example, the user characteristic information is behavior information of the user, and the behavior information of the user may be action track information of the user, for example, if it is determined from the action track of the user that the user moves straight toward the gate entrance, it may be determined that the user has an intention to enter the gate.
In an optional mode of the embodiment of the application, the second target position is an image acquisition position at an entrance of the gate, and the first target is located on the periphery of the entrance of the gate.
In this embodiment, the second target position may be an image capturing position at an entrance of the gate, and the first target position may be located at a periphery of the entrance of the gate.
In practical use, the second target position may be an image acquisition position for performing face detection, and the first target position may be a must-pass area when moving to the second target position.
In an optional manner of the embodiment of the application, if the identity of the designated user in the second image is determined based on the first image recognition database, the method further includes:
constructing a second image identification database based on second image identification data corresponding to the specified user;
upon receiving a third captured image of a third image capture device at a third target location, an identity of the user in the third image is determined based on the second image recognition database.
In the embodiment of the application, the designated user is a user who passes identity recognition, taking a gate system as an example, that is, the user is permitted to enter the inner side of the gate after face brushing recognition is successful. The second image recognition database may be suggested based on the image recognition data of the specified user for identification of the user at the exit of the gate based on the second image recognition database.
In this embodiment of the application, the third target position may be an image capturing position at the gate exit, that is, when the user leaves the gate from the gate exit, a third image is captured at the third target position, and the user is identified based on the third image.
The second image identification database is constructed based on the two image identification data, namely the image identification database is constructed for the user entering the entrance of the gate. The data volume in the constructed second image recognition database is small, so that the data comparison volume of the user in the third image during identity recognition can be reduced, and the recognition speed is improved.

In the scheme, the first image identification data of the target user is added to the first image identification database, so that the first image identification database has higher pertinence when the user in the second image is identified, the comparison amount of the characteristic data is less, the identification speed can be improved, and the use requirements under the scene with larger pedestrian volume are met.
