in one embodiment of the present invention, as shown in fig. 2, a camera 1011 is included in the face capturing device 101.
The camera 1011 is configured to collect a face image of the user, and send the collected face image to the control device 102.
In this embodiment, when only one camera is included in the face capturing apparatus, the camera may be disposed at any position on the top surface of the printer body. For example, at a location adjacent to either of the top side edges.
In this embodiment, when including a plurality of cameras in people's face collection equipment, a plurality of cameras can be even the setting on printer body top surface.
In the second type of the above-mentioned methods,
in an embodiment of the present invention, as shown in fig. 3, the face capturing device 101 may include a camera 1011 and an infrared sensor 1012;
the infrared sensor 1012 is used for detecting whether an infrared target exists in a preset area, and if so, triggering the camera 1011;
the camera 1011 is configured to collect the face image under the trigger of the infrared sensor 1012.
In this embodiment, a preset area may be set for the infrared sensor according to the service requirement. For example, a circular area with a radius of 5 meters is a preset area with the infrared sensor as a center. When the infrared sensor detects that an infrared target exists in the preset area, it indicates that a user may need to use the printer to execute printing operation, and therefore the camera is triggered.
In this embodiment, when the camera receives the trigger of the infrared sensor, the camera enters a shooting state. Then the camera collects the face of the user and collects the face image of the user.
In this embodiment, the number of cameras may be one or more. The position of the camera in the printer body is basically the same as that explained in the previous embodiment, and will not be described again here.
In this embodiment, the number of infrared sensors may be determined according to the service requirement. The number of infrared sensors may be one or more. The corresponding relation between the infrared sensor and the camera at least comprises the following types: first, one infrared sensor corresponds to only one camera; second, one infrared sensor may correspond to a plurality of cameras. When the infrared sensor senses that the infrared target exists in the preset area, the corresponding camera is triggered.
In this embodiment, the specific types of the camera and the infrared sensor can be determined according to the business requirements. For example, a high-definition camera may be used.
According to the embodiment, the camera collects the face image only under the triggering of the infrared sensor, and the visible camera is not required to be in a collection state continuously. Therefore, the energy consumption of the camera can be saved to a certain extent.
In an embodiment of the present invention, as shown in fig. 4, the control device 102 may include a memory 1021 and a control chip 1022;
the memory 1021 is used for storing the corresponding relation between at least one sample face and at least one sample printing authority;
the control chip 1022 is configured to identify a face of a user in the face image; determining whether a target sample face identical to the user face exists in the at least one sample face, and if so, judging that the user has printing authority; and determining the sample printing authority corresponding to the target sample human face as the printing authority corresponding to the user according to the corresponding relation stored in the memory 1021.
In this embodiment, a plurality of sample faces may be stored in the memory according to the service requirement, where each sample face is a face of a user who may use the printer. Each sample face corresponds to a sample printing authority. And the sample printing authority corresponding to each sample face can be determined according to the service requirement. The sample printing authority can include but is not limited to at least one or more of a printing function authority, a copying function authority, a scanning function authority, a printing paper sheet number authority, a copying paper sheet number authority, a scanning times authority and a printing time period authority.
In this embodiment, when receiving a face image sent by a face acquisition device, the control chip may determine whether a face exists in the face image according to RGB values in the face image. For example, it may be determined whether the percentage of RGB values located in a preset skin color RGB value interval among all RGB values included in the face image reaches a preset percentage, and if so, it is determined that a face exists in the face image.
In this embodiment, when the control chip determines that a human face exists in the human face image, each feature point in the human face is acquired, and the euclidean distance, the curvature and the angle between the feature points are determined. And comparing the Euclidean distance, the curvature and the angle among the characteristic points in the face image with the Euclidean distance, the curvature and the angle among the characteristic points in each sample face respectively. And determining the sample face with the same or similar Euclidean distance, curvature and angle with each characteristic point in the face image as a target sample face through comparison. And then determining the sample printing authority corresponding to the target sample face as the printing authority of the user corresponding to the face image according to the corresponding relation stored in the memory.
In the embodiment, the types of the memory and the control chip can be determined according to the service requirement.
According to the embodiment, the control chip identifies the face of the user in the face image, determines that the target sample face identical to the face of the user exists in each sample face, and determines the sample printing authority corresponding to the target sample face as the printing authority corresponding to the user according to the corresponding relation stored in the memory. Because the corresponding relation between the sample face and the sample printing relation is stored in the memory, when the control chip determines that the target sample face exists, the printing authority corresponding to the user can be rapidly determined according to the corresponding relation.
In an embodiment of the present invention, as shown in fig. 5, the printer may further include a light supplement device 104 and a light collection device 105;
the light collection device 105 is configured to collect a current light intensity value in an environment where the face collection device 101 is located, and send the current light intensity value to the control device 102;
the control device 102 is further configured to determine whether the light supplement device 104 needs to be triggered according to the current light intensity value sent by the light acquisition device 105, and if so, trigger the light supplement device 104;
the light supplement device 104 is configured to supplement light for the face acquisition device 101 under the trigger of the control device 102.
In this embodiment, the light collection device may collect, in real time or at a certain period, a current light intensity value in an environment where the face collection device is located, and send the collected current light intensity value to the control device, so that the control device determines whether the light supplement device needs to be triggered to supplement light for the face collection device according to the current light intensity value.
In this embodiment, when the control device receives a current light intensity value sent by the light collection device, it is determined whether the light supplement device needs to be triggered to supplement light for the face collection device according to the current light intensity value. And if the fact that the light supplementing device does not need to be triggered to supplement light for the face acquisition device is determined, it is indicated that the light intensity in the environment is enough to enable the face acquisition device to acquire a clear face image. If it is determined that the light supplementing device needs to be triggered to supplement light for the face collecting device, it is stated that light intensity in the environment cannot enable the face collecting device to collect clear face images, the light supplementing device needs to be used for supplementing light to the face collecting device, and then the face collecting device can collect clear face images.
In this embodiment, the specific type of the light collection device may be determined according to the business requirements. For example, the light collection device may be a light sensor. The specific type of the supplementary lighting device can also be determined according to the service requirement. For example, it may be an array of light emitting diodes.
According to the embodiment, through interaction among the light acquisition equipment, the control equipment and the light supplement equipment, even when the light intensity in the environment where the face acquisition equipment is located is insufficient, the light intensity environment capable of acquiring clear face images can be provided for the face acquisition equipment.
In an embodiment of the present invention, the control device 102 is configured to determine whether the current light intensity value is smaller than a preset light intensity threshold, and if so, determine the light intensity of the supplementary light according to formula (1), and trigger the supplementary light device 104;
E＝K×(T-S) (1)
wherein the E represents the light intensity of the supplementary lighting; the T characterizes the light intensity threshold; the S characterizes the current light intensity value; the K represents the light supplement coefficient;
the light supplement device 104 is configured to emit light with an intensity equal to that of the light supplement light under the trigger of the control device 102.
In this embodiment, the light intensity threshold may be determined according to traffic requirements. For example, the light intensity threshold is 60 lux.
In this embodiment, when the control device determines that the current light intensity value is not less than the light intensity threshold, it indicates that the light intensity in the environment meets the requirement that the face acquisition device acquires a clear face image, and at this time, the light supplement device is not required to supplement light for the face acquisition device. When the control device judges that the current light intensity value is smaller than the light intensity threshold value, it is described that the light intensity in the environment cannot meet the requirement that the face acquisition device acquires a clear face image, and at the moment, the light supplement device needs to be used for supplementing light for the face acquisition device, so that the face acquisition device can acquire the clear face image.
In this embodiment, when the control device determines that the current light intensity value is smaller than the preset light intensity threshold value, the light supplement intensity may be calculated according to formula (1), and the light supplement device is triggered to emit light with the intensity being the light supplement intensity, so as to supplement light to the face collection device. The fill-in light coefficient in the formula (1) may be determined according to the service requirement. For example, the light supplement coefficient may be determined according to the type of the light supplement device, the power of the light supplement device, and the distance between the light supplement device and the face acquisition device.
According to the above embodiment, because the luminous intensity of the light that the light filling equipment sent is the light filling luminous intensity that the current light intensity value in controlgear according to luminous intensity threshold value and the environment confirmed, consequently, the light filling equipment can be more effectual for face collection equipment light filling.
In one embodiment of the present invention, as shown in FIG. 6, the printer may also include an input device 106;
the input device 106 is configured to send the user information input by the user to the control device 102;
the control device 102 is further configured to determine whether the user information sent by the input device 106 is legal, and if so, trigger the face acquisition device 101 to acquire the face image.
In this embodiment, the specific type of the input device may be determined according to the service requirement. For example, the intake device may include, but is not limited to, one or more of a credential scanning device, a fingerprint acquisition device, and a password entry device.
In this embodiment, the certificate scanning device, the fingerprint collecting device and the password input device can all select specific types according to business requirements.
In this embodiment, where the input device is a document scanning device, the user can place a particular document (such as any of a print card, a work card, or an identification card) on the document scanning device. The credential scanning device can then scan the credential for user information (e.g., the user's name, number, department, etc.) and send the scanned user information to the control device. When receiving the user information, the control device may determine whether the user information such as the name, number, and department in the user information is in the pre-recorded user information. If so, determining that the user information is legal, and then triggering the face acquisition equipment to acquire the face image so as to verify whether the user has the printing authority again by using the face image acquired by the face acquisition equipment. The situation that personnel picking up the certificate maliciously acquire the printing permission by using the picked certificate is avoided.
In this embodiment, when the input device is a fingerprint acquisition device, the user may place an appointed finger on the fingerprint acquisition device. And then the fingerprint acquisition equipment acquires the fingerprint of the user and sends the acquired fingerprint of the user to the control equipment as user information.
In this embodiment, when the input device is a password input device, the user may input the user password corresponding to the user into the password input device. The password input device then transmits the user password input by the user to the control device as user information.

And then triggering the face acquisition equipment to acquire the face image so as to verify whether the user has the printing authority again by using the face image acquired by the face acquisition equipment. And the situation that a person who cracks the user password maliciously obtains the printing permission by using the cracked user password is avoided.
According to the embodiment, when the control device judges that the user information sent by the input device is legal, the control device needs to trigger the face acquisition device to acquire the face image. The face image is used for carrying out secondary verification on the user, so that the probability that malicious personnel acquire the printing authority is reduced.
