1 is a block diagram of an electronic gatekeeper in accordance with an embodiment of the present invention. The electronic gatekeeper device 100 can perform an identity check program and provide an automatic renewal function. The electronic gate guard device 100 includes an image capturing unit 110, a storage unit 120, an audio output unit 130, a processing unit 140, a sensing unit 150, a first input/output hole 160, and a second input/output hole 170. The processing unit 140 is coupled to the image capturing unit 110, the storage unit 120, the audio output unit 130, the sensing unit 150, the first input/output hole 160, and the second input/output hole 170.

The image capturing unit 110 is configured to capture a sequence of images, the image sequence including a plurality of images having a target person. The image capturing unit 110 includes, for example, a charge coupled device (CCD) lens, a complementary metal oxide semiconductor transistor (CMOS) lens, or an infrared lens camera, a camera, and the like. But it is not limited to this. In addition, the image capturing unit 110 further includes a depth camera, a stereo camera with multiple lenses, a combination of multiple cameras for constructing a three-dimensional image, or other image sensors capable of detecting three-dimensional spatial information. An image capture device that takes depth information.

In this embodiment, the image capturing unit 110 is disposed, for example, in front of the electronic gate guard device 100 to detect and capture an image sequence of a specific angle in front of the electronic gate guard device 100. In other embodiments, the image capturing unit 110 may further include a plurality of image capturing devices, and may be disposed around the electronic gate guard device 100 to detect and capture a detection range centered on the electronic gate guard device 100. Image sequence. In other embodiments, the image capturing unit 110 further has an illumination component for performing a fill light action when the light is insufficient to ensure the sharpness of the image captured by the image capture unit 110.

The storage unit 120 is configured to store the image sequence. The storage unit 120 is, for example, any type of fixed or removable random access memory (RAM), read-only memory (ROM), flash memory (Flash memory), hard Discs or other similar devices or combinations of these devices are not limited thereto.

The audio output unit 130 is, for example, a speaker, a speaker, or the like. It is used to emit an audio signal. The sensing unit 150 is configured to detect and read a legal passport of the target person to obtain identification data. The legal pass is, for example, an inductive electronic chip or proximity card using Radio Frequency Identification (RFID) technology, or a proximity card including optical or magnetic bar codes. The sensing unit 150 is, for example, a reading device such as a radio frequency identification reader, an optical or magnetic bar code reader, which corresponds to the type of legal pass. The first input and output hole 160 is for receiving or outputting an identification object. The identification object is, for example, a document such as an identity card, a driver's license, a health insurance card, and the like of the target person. The second input/output hole 170 is for receiving or outputting a temporary passport.

The processing unit 140 is, for example, a central processing unit (CPU), a graphics processing unit (GPU), or other programmable microprocessor (Microprocessor). The processing unit 140 obtains the image sequence from the image capturing unit 110 and stores the image sequence to the storage unit 120, and detects whether a target person exists in the image sequence. For example, when the target person is detected in the image sequence, the processing unit 140 calculates the relative distance between the target person and the image capturing unit 110 in the image sequence, and when the relative distance is less than the detection distance, the processing unit 140 controls the audio. The output unit 130 emits an audio signal and performs an identity check procedure.

For example, after the image capturing unit 110 captures the image sequence, the image is stored in the storage unit 120 (for example, a memory or a hard disk) through an input/output (I/O) unit, and the processing unit 140 The image sequence stored in the storage unit 120 is captured, and the recognition process is performed by the processing unit 140 to detect whether the same target person exists in the image sequence, and the target person and the image in the image are calculated. Taking the relative distance of the unit 110, according to the control audio output unit 130 to send an audio signal, and performing an identity check procedure for the target person to determine whether the target person is a legal person or a target if the target person has a legal passport When a person does not have a valid pass, he or she issues a temporary pass.

The electronic gate device 100 described above is used to explain how to perform the above-mentioned identity checking procedure. 2 is a flow chart of a method for personnel management of an entrance and exit according to an embodiment of the invention. Referring to FIG. 1 and FIG. 2 simultaneously, in step S205, the image capturing unit 110 is used to capture the image sequence of the target person. Here, a start condition may be set in advance to enable the image capturing unit 110 to capture the image of the target person when the start condition is met. For example, a sensor, such as an infrared sensor, may be disposed in the vicinity of the image capturing unit 110, and the infrared sensor is used to detect whether a target person is located within a range in which the image capturing unit 110 can capture the image. If the infrared sensor detects that a target person appears in front of the image capturing unit 110, the image capturing unit 110 is enabled to start capturing images. In addition, a start button may be provided, and the image capturing unit 110 is activated through the start button. However, the above is merely illustrative and is not limited thereto.

Alternatively, the image capturing unit 110 may always capture the image sequence without setting any activation conditions, and the processing unit 140 may continue to analyze the image sequence to determine whether a target person enters the imaging range.

When the image sequence including the target person is obtained, the processing unit 140 may perform image processing on the target person in each image of the image sequence, wherein the processing unit 140 may use, for example, an AdaBoost algorithm or other existing face recognition. Algorithms (eg, using Haar-like features for face recognition actions) to obtain faces in each image in the image sequence, to determine whether there is a target person at the corresponding location, and to identify each target in each image Whether the person is the same person.

Next, in step S210, the processing unit 140 calculates the relative distance between the target person and the image capturing unit 110 according to the image sequence. Specifically, in the embodiment, the image capturing unit 110 is, for example, a depth camera or a stereo camera, so the captured image sequence further includes depth information. Thereby, the processing unit 140 can obtain the depth information from the image sequence, and calculate the relative distance between the target person and the image capturing unit 110 in the image sequence according to the depth information.

Thereafter, in step S215, the processing unit 140 determines whether the relative distance is less than a detection distance. When the relative distance is less than the detection distance, in step S220, the processing unit 140 controls the audio output unit 130 to emit an audio signal, and in step S225, the processing unit 140 performs an identity verification procedure. Here, the detection distance is a threshold for the execution of the identity check program, for example, set to 5 meters. When the target person enters the detection distance of the electronic gate guard device 100, the electronic gatekeeper device 100 initiates an identity check procedure to check the identity of the target person.

In detail, the identity verification program of this embodiment may include steps S2251 to S2254. In step S2251, the processing unit 140 may determine whether the target person has a valid passport. The processing unit 140 sets, for example, a preset time, and if a legal passport of the target person is detected within the preset time period, it is determined that the target person has a legal passport; and when the preset time exceeds the preset time, there is still no detection. When the legal pass of the target person is detected, it is determined that the target person does not have legal passage. The status of the card. The above manner of determining whether the target person has a legal passport by using the preset time is only an example, and is not limited herein. Therefore, if the target person has a legal pass, the process proceeds to step S2252, and the legal pass of the target person is detected and read through the sensing unit 150 to obtain the identification data. The identification data is, for example, an RFID electronic identification code, an optical barcode or a magnetic barcode. Next, in step S2253, the processing unit 140 compares whether the identification data matches the login data, thereby determining whether the target person is a legitimate person.

Here, the embodiment of FIG. 3 is used to explain how the processing unit 140 determines whether the target person is a legitimate person. In this embodiment, the storage unit 120 includes an identity database. Here, the identity database stores login data corresponding to each user (ie, a legal person), and the login data includes a registration code. Therefore, in step S305, the processing unit 140 searches for the identity database, and in step S310, the processing unit 140 determines whether the registration code matching the identification data can be found in the database itself. When the registration code corresponding to the identification data is found in the self-database, in step S315, the processing unit 140 determines that the target person is a legal person. If the registration code corresponding to the identification data cannot be found, the process proceeds to step S320 and it is determined that the target person is not a legal person.

If the target personnel does not have a valid passport, the process proceeds to step S2254. The processing unit 140 can receive the identification object through the first input/output hole 160 and output through the second input/output hole 170. A temporary pass corresponding to the identified object. The first input/output hole 160 is, for example, an insertion port of a document such as an identity card or a driver's license, and the second input/output hole 170 is, for example, a temporary release. The exit of the pass. Therefore, the processing unit 140 may analyze the identification object to obtain the user data in the identification object, and accordingly issue a corresponding temporary passport to the target person. The above analysis method is, for example, performing image processing on the identification object, thereby extracting the identity information of the target person's name, portrait, and the like.

Thereby, the present embodiment passes the identification check procedure to verify the legal pass of the target person when the target person has a legal pass, and determines that the target person is a legal person when confirming that the identity is correct. When the target person does not have a valid passport, he or she can receive the identification object and issue a temporary pass to provide automatic replacement. Accordingly, the embodiment can effectively realize the electronic personnel control of the entrance and exit. Moreover, in this embodiment, the depth information obtained by the image capturing unit 110 by the electronic gate guard device 100 is used to determine whether the target person enters the detection distance of the electronic gate guard device 100, so that the warning is accurately and immediately issued. Compared with the two-dimensional image capturing device, the electronic door guard device 100 of the embodiment can detect the target person more efficiently when the target person is detected, because the relative distance cannot be considered and the remote noise may be interfered. Reduce the misjudgment caused by the external environment.

The electronic gate guard device 100 of the foregoing embodiment determines that the target person is a legitimate person by verifying that the legal person's legal pass is correct, or issues a temporary pass based on the identification object when the target person does not have a legal pass. In other embodiments, the electronic gatekeeper device 100 can also incorporate other verification conditions, such as voiceprints or face recognition of the target person, as a basis for the identity verification process. The following examples are given in detail to illustrate.

4 is a diagram of an identity verification program according to an embodiment of the invention. Law flow chart. In this embodiment, the processing unit 140 further verifies the voiceprint to verify the identity of the target person. It should be noted that the process of FIG. 4 may be performed, for example, after the processing unit 140 determines that the identification data matches the login data, or the processing unit 140 may perform the voiceprint verification before determining the identification data of the target personnel. The order of verification for the above conditions is not limited. Referring to FIG. 4, in step S405, the processing unit 140 controls the audio output unit 130 to emit a first voice signal. Next, in step S410, the processing unit 140 receives the second voice signal of the target person in response to the first voice signal through the audio receiving unit. The audio receiving unit here is, for example, a microphone or other sound receiving device, and the first voice signal is, for example, voice information such as “please apply for a name” to prompt the target person to speak the specified voice in response to the first voice signal. The information is used as the second voice signal.

Thereafter, in step S415, the processing unit 140 executes a speech recognition program to determine whether the second speech signal conforms to the registered speech signal included in the login data. When the second voice signal conforms to the registration voice signal, in step S420, the processing unit 140 may determine that the target person is a legitimate person. When the second voice signal does not comply with the registered voice signal, the process proceeds to step S425 and it is determined that the target person is not a legal person. The speech recognition program may include Voiceprint Recognition and/or Speech Identification, thereby utilizing speech segments spoken by the target person, and by, for example, Mel-Frequency Cepstral Coefficients. The MFCC) algorithm is used to perform a speech recognition process on the voiceprint for the target person. The implementation of the speech recognition program in this embodiment can be implemented by a plurality of algorithms, and the present invention is not limited thereto. Accordingly, based on Figure 4, based on speech Identifying the verification process performed, the electronic gatekeeper device 100 can perform a verification process for the target person by combining the identification data corresponding to the target person and the verification of the voiceprint.

Similarly, for the case where the target person does not have a valid passport, the processing unit 140 may perform voiceprint verification on the target person to check the identity after or before the step of receiving the identification object by the first input/output hole 160, where the identity is not checked. Set limits.

FIG. 5 is a flow chart of a method for checking an identity in accordance with another embodiment of the present invention. In this embodiment, the processing unit 140 further passes the face recognition to check the identity of the target person. Similar to the foregoing embodiment, the process of FIG. 5 may be performed, for example, after the processing unit 140 determines that the identification data matches the login data, or may perform face recognition before determining the identification data of the target person, and the present invention does not Limit the order of verification for the above conditions. Referring to FIG. 5, in step S505, the processing unit 140 controls the audio output unit 130 to emit a third voice signal, where the third voice signal is, for example, "Please approach forward", etc., to prompt the target personnel to face the image. The prompt message of the unit 110 is such that the image capturing unit 110 can capture a clear image. Next, in step S510, the processing unit 140 drives the image capturing unit 110 to capture an image of the face object including the target person.

Thereafter, in step S515, the processing unit 140 performs a face recognition algorithm to determine whether the first facial feature data obtained from the image conforms to the preset facial feature data. When the first facial feature data meets the preset facial feature data, in step S520, the processing unit 140 determines that the target person is a legal person. When the first facial feature data does not meet the preset facial feature data, the process proceeds to step S525 and determines The target person is not a legal person.

Here, the technique for detecting a face includes, but is not limited to, using an AdaBoost algorithm or other existing face recognition algorithms (eg, using a Haar-like feature for face recognition actions) to obtain images in each image. Face. Before detecting the facial features, the processing unit 140 may also perform a background filtering action. For example, the image capturing unit 110 may capture a background image of a non-present image in advance to subtract the image including the portrait from the background image after obtaining the image of the target person, so that the background can be filtered out. After that, the image that filters out the back image can be converted into a grayscale image and then converted into a binarized image. At this time, the processing unit 140 can detect the facial features in the binarized image, and compare the obtained facial objects with the samples of the facial feature data of the login data. Accordingly, the electronic gatekeeper device 100 can perform the identification process for the target person by combining the identification data corresponding to the target person and the verification combination of the face object by the verification process performed by the face recognition in FIG. 5.

Similarly, in the case where the target person does not have a legal passport, the above procedure for performing face recognition for performing identity verification may also be performed after or before the step of receiving the identification object by the first input/output hole 160, the present invention not limited.

In addition, the electronic gate guard device 100 can also use the above-mentioned identification data, voiceprint, and facial objects as verification basis for identity verification. Thereby, the electronic gate guard device 100 uses the legal pass for verifying the target person or its identification object to check its identity, and can further verify the target person's voiceprint, facial features or a combination of at least one of the above conditions, thereby enhancing the identity check. The accuracy and security of the program.

In addition, it is worth mentioning that, in an embodiment, when the electronic guard device After issuing the temporary pass 100, the electronic gatekeeper device 100 can also provide a mechanism for automatically recovering temporary passes. The flow of recovering a temporary pass is explained below by the embodiment of FIG. 6.

FIG. 6 is a flow chart of a method for recycling a pass according to an embodiment of the invention. In the case that the target person does not have the legal passport, in step S605, the processing unit 140 may drive the image capturing unit 110 to capture the first image including the face object of the target person, and in step S610, the processing unit 140 performs The face recognition algorithm obtains the first facial feature data. In other words, the first facial feature data can be used as a basis for later identifying the target person. The implementation of the face recognition algorithm to obtain the first facial feature data is similar to the previous embodiment, so please refer to the foregoing. The above steps S605 and S610 may be performed in step S2254 of FIG. 2 or before or after step S2254, which is not limited by the present invention.

Next, in step S615, the temporary passport is received by the second input/output hole 170, and after receiving the temporary passport, the processing unit 140 triggers the image capturing unit 110 to capture the facial object including the target person in step S620. image. Thereafter, in step S625, the processing unit 140 performs a face recognition algorithm to obtain a second facial feature. The above manner regarding the face recognition algorithm and the processing unit 140 obtaining the face object is similar to the previous embodiment, so please refer to the foregoing.

In step S630, the processing unit 140 determines whether the second facial feature data meets the first facial feature data corresponding to the temporary passport. When the second facial feature data meets the first facial feature data, the processing unit 140 outputs the identification object corresponding to the first facial feature data through the first input/output hole 160 in step S635. and When the second facial feature data does not conform to the first facial feature data, then in step S640, the temporary passport is outputted through the second input/output hole 170. The above steps S615 to S640 can be performed after the step S2254 of FIG. 2 . Thereby, the electronic janitor device 100 of the present embodiment can exchange the corresponding identification object back to the target person by comparing the temporary pass and the facial feature data of the target person after realizing the function of recovering the temporary pass.
