[0043] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0045] See also Figure 1 , which shows a charging pile system for face recognition provided by an embodiment of the present invention, which is described in detail as follows:

[0046] The above-mentioned charging pile system for face recognition comprises: a charging pile body 1, a camera 2 and a screen 3 arranged on the front side of the charging pile body 1, an angle adjustment mechanism and a charging control module;

[0047] The screen 3 is arranged on the front side of the charging pile body; the camera 2 is embedded in the upper part of the screen 3 and is fixedly connected to the screen 3;

[0048] Camera 2 is used to obtain a face image and send the face image to the host computer; wherein the host computer is used to determine whether the face image is qualified; if qualified, the face image is recognized and the recognized face information is sent to the charging control module; if unqualified, the screen 3 adjustment instruction is sent to the angle adjustment mechanism;

[0049] The angle adjustment mechanism is connected to the screen 3 and is used to adjust the angle of the screen 3 after receiving a screen 3 adjustment instruction;

[0050] The charging control module is used to start charging according to facial information.

[0051] In the embodiment of the present invention, an angle adjustment mechanism is provided for the charging pile to adjust the angles of the camera 2 and the screen 3; the upper computer determines whether the face image is qualified, and sends an angle adjustment instruction to the angle adjustment mechanism when it is unqualified; wherein the upper computer can be a control terminal on a cloud platform, a local platform or a charging pile system for face recognition, etc. The angle adjustment mechanism adjusts the angles of the camera 2 and the screen 3, so that the camera 2 can obtain a clearer and more standard face image, improve the accuracy of face recognition, and greatly improve the user experience; at the same time, the camera 2 is fixedly connected to the screen 3 and integrated on the front side of the charging pile body 1. Adjusting the angle of the camera 2 is also adjusting the angle of the screen 3, and at the same time, the user can clearly see the information on the screen 3.

[0052] In a possible implementation, the screen 3 is rectangular; the angle adjustment mechanism may include: a horizontal adjustment portion and a vertical adjustment portion;

[0053] The lateral adjustment part is used to drive the screen 3 to rotate left and right, and the longitudinal adjustment part is used to drive the screen 3 to rotate up and down.

[0054] refer to Figure 1 In the embodiment of the present invention, a horizontal adjustment part and a vertical adjustment part are provided so that the screen 3 can be rotated up and down or left and right.

[0055] For example, refer to Figure 2 , you can rotate inwards with the lower frame of the screen 3 as the axis, or rotate inwards with the upper frame of the screen 3 as the axis, so as to adjust the pitch angle of the screen. You can rotate inwards with the left frame of the screen 3 as the axis, or move inwards with the right frame of the screen 3 as the axis, so as to adjust the yaw angle of the screen.

[0056] Among them, the structures of the lateral adjustment part and the longitudinal adjustment part are conventional technical means in the field, and the details will not be repeated here.

[0057] In a possible implementation, adjusting the angle of the screen 3 may include:

[0058] S101: Determine the facial posture of the target according to the face image;

[0059] Facial posture indicates the direction of the face. When the height of the camera 2 is fixed, the facial posture in the face image obtained by the camera 2 is different for different users with different heights; the facial posture is also different when the user's face is tilted to the left or right. When the facial posture is facing forward, the accuracy of face recognition is high; when the facial posture is facing sideways, the accuracy of face recognition is reduced.

[0060] S102: Obtain the current light intensity, and determine the target angle of screen 3 according to the current light intensity and the target's facial posture;

[0061] S103: Adjust the angle of screen 3 according to the target angle of screen 3.

[0062] Based on the above, it can be seen that facial posture affects the accuracy of face recognition, and light intensity also affects face recognition. Therefore, in the embodiment of the present invention, the target angle of screen 3 is determined according to the light intensity and target posture, and screen 3 is adjusted so that the face image obtained by camera 2 is facing forward. At the same time, by adjusting screen 3, the light intensity is prevented from affecting the accuracy of face recognition.

[0063] Exemplarily, when the user's face in the facial image is facing upward, the screen 3 is controlled to rotate inwardly with the upper frame as the axis, so that the screen 3 is parallel to the user's face to obtain a clear facial image.

[0064] In a possible implementation, S102 may include:

[0065] S1021: Determine a facial pitch angle and a facial yaw angle according to the facial posture;

[0066] S1022: Determine a light deviation angle according to the current light intensity; wherein the light deviation angle is a positive value;

[0067] S1023: Determine the target angle of screen 3 according to the facial pitch angle, facial yaw angle and light deviation angle.

[0068] When the light intensity is too high, the screen 3 can be rotated up and down to avoid the influence of light on face recognition, while ensuring that the user can see the screen 3 clearly, so that the user can adjust the posture in front of the camera or understand the screen information. In the embodiment of the present invention, the facial posture and light intensity are comprehensively considered to determine the target angle of the screen 3, so that the camera 2 can obtain a clear face image and improve the accuracy of face recognition.

[0069] In a possible implementation manner, the target angle of the screen 3 may include: a screen pitch angle and a screen yaw angle; S1023 may include:

[0070] 1. Calculate the difference between the absolute value of the facial pitch angle and the light deviation angle;

[0071] 2. If the difference is less than the preset difference and the face pitch angle is positive, the light deviation angle is used as the screen pitch angle;

[0072] 3. If the difference is less than the preset difference and the face pitch angle is negative, the negative light deviation angle is used as the screen pitch angle;

[0073] 4. If the difference is not less than the preset difference, the face pitch angle is used as the screen pitch angle;

[0074] 5. Use the facial yaw angle as the screen yaw angle.

[0075] When the light is strong, the screen pitch angle can be adjusted so that the screen 3 is tilted up or down to prevent strong light from affecting face recognition. The stronger the light, the larger the adjustment angle can be. At the same time, the screen 3 is parallel to the user's face, so a clear image can be obtained, and it is also convenient for the user to see the screen 3 clearly. Therefore, the screen pitch angle and the screen yaw angle can be adjusted so that the screen 3 is parallel to the user's face.

[0076] When the absolute value of the face pitch angle is smaller than the light deviation angle, it means that the angles adjusted based on light intensity or face posture are similar, and the screen 3 can meet the requirements regardless of whether it is adjusted based on light intensity or face posture. Therefore, when the impact on face recognition is not significant, the impact of light intensity is given priority, so that the user can see the screen 3 clearly while ensuring the accuracy of face recognition.

[0077] When the difference between the two is large, facial posture is given priority and the facial pitch angle is used as the screen pitch angle to ensure the accuracy of face recognition.

[0078] The influence of light intensity is not significantly affected by adjusting the screen 3 left and right, so the face yaw angle is directly used as the screen yaw angle.

[0079] In a possible implementation, S1022 may include:

[0080] 1. Multiply the current light intensity by the angle coefficient to get the light deviation angle.

[0081] In the embodiment of the present invention, the light intensity is directly multiplied by the angle coefficient to obtain the light deviation angle. The greater the light intensity, the greater the angle of rotation of the screen 3 to avoid strong light affecting face recognition.

[0082] In a possible implementation, starting charging according to facial information may specifically be:

[0083] S201: Compare the facial information with the pre-stored user information;

[0084] S202: If the facial information is consistent with the pre-stored user information, charging is started;

[0085] S203: If the facial information is inconsistent with the pre-stored user information, charging is not started.

[0086] The charging pile in the embodiment of the present invention pre-stores the user information of the registered user. If the facial information is consistent with the pre-stored user information, it means that the user is a legitimate user, and charging can be started. If the facial information is inconsistent with the pre-stored user information, it means that the user is not registered and is an illegal user, and the charging service cannot be provided to the user, and charging will not be started.

[0087] In a possible implementation, the host computer may be a cloud platform.

[0088] In a possible implementation, the charging pile may further include: a flash light 4;

[0089] The flash 4 is arranged on the side of the camera 2 for fill light.

[0090] The embodiment of the present invention is also provided with a flash 4 to provide fill light in dim conditions to improve the accuracy of face recognition.

[0091] In a possible implementation, the charging pile may further include: a code scanning device;

[0092] The code scanning device is connected to the charging control module, and is used to obtain the user's identity code and send the user's identity code to the charging control module;

[0093] The charging control module is also used to start charging according to the identity code.

[0094] In the embodiment of the present invention, a code scanning device can also be provided to collect the user's identity code. The charging control module compares the identity code with the pre-stored identity code. If the comparison is consistent, it means that the user has been registered and is a legal user, and charging can be started; otherwise, charging cannot be started.

[0095] By setting up a code scanning device, more feasible identity authentication methods are provided to users, which facilitates user operation and improves user experience.

[0096] Corresponding to the above embodiments, an embodiment of the present invention further provides a charging management platform, which is used in large charging stations and can serve as a host computer to communicate with the face recognition charging pile system provided in the above embodiments, and is used to perform charging management on the above face recognition charging pile system.

[0097] Specifically, the charging management platform may include functions such as charging power allocation management, charging rate management, and charging pile operation and maintenance management.

[0098] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
