First, the enterprise resource planning system 100 of the present invention will be described in detail below with reference to the block diagram of FIG. 1 and the block diagram of FIG. 3 .

First, the enterprise-wide resource management system 100 having a worker working time control function of the present invention includes a worker access control device 110 as shown in FIG. 1 ; The management server 120 and the management terminal 130; includes.

Here, the worker access control device 110 and the management server 120 , the management server 120 and the management terminal 130 establish a mutual wired or wireless communication network as shown in FIG. 1 to transmit and receive information and signals. Build the entire system in a state where this is possible.

According to the implementation, the worker access control device 110 and the management terminal 130 directly establish a mutual wired or wireless communication network without a relay device through the management server 120 to form a state in which mutual information and signal transmission and reception are possible. You may.

As shown in FIG. 1, the worker access management device 110 is installed at each work site (wp) and records the entrance and exit photos for each worker and access information about the arrival and departure times by photographing the worker's face when entering and leaving the office. As a terminal device for generating, depending on implementation, input of identification codes for each worker may also be provided such as face photographing when going to and from work.

The management server 120 receives the access information generated from the worker access management device 110, based on the received access information, can generate time and attendance information for each worker's daily working hours and accumulated working hours, and T&A information are stored and managed.

The management terminal 130 accesses the management server 120 to receive and use access information and attendance information, so that the manager can check the information anytime, anywhere.

Basically, the worker access control device 110 includes a signal input unit 110K such as a keypad for input of various information necessary for registration and identification of workers, a photographing unit 110C provided with a photographing module such as a cam or camera, a display and Similarly, a display unit 110D provided as an image output module for outputting visual information and a speaker unit (not shown) provided as an audio output module for outputting auditory information such as a speaker are installed.

In some implementations, the signal input unit 110K and the display unit 110D may be integrated as a touch screen and installed on one side of the worker access control device 110, so that both input and output of information may be performed on the touch screen.

Furthermore, the worker access control device 110 establishes a wired or wireless communication network with the management server 120 and the management terminal 130, and a communication unit 110T provided as a communication module for mutual information and signal transmission and reception is installed. have.

Specifically, when a worker goes to work at the work site wp or leaves work from the work site wp, the worker enters and leaves his/her departure from the work site wp through the photographing unit 110C of the worker access control device 110 installed at the entrance of the work site wp. It creates and records access information about photos and arrival and departure times in the worker access management device 110 .

Depending on the implementation, an identification code such as a resident number, management number, driver's license number, etc. representing the worker's own identity is inputted into the signal input unit 110K such as a keypad or a touch screen, and then, if approved, through the photographing unit 110C. It may be provided so that filming can proceed.

In addition to this, the worker access control device 110 includes a photo generation unit 111, a reference photo storage unit 112, a worker determination unit 113, a recognition rate analysis unit 114a, and a reference photo update as shown in FIG. unit 114b, sharpness analysis unit 115b, photo generation control unit 115b, recognition area display unit 116, information display unit 117, output language change unit 118, character recognition unit 119 and access information generation Includes part (not shown).

First, the photographing unit 110C means a camera module means for photographing a worker who approaches within a certain range of the worker access management device for work or leaving.

Next, the photo generating unit 111 is configured to recognize only the face F of the worker photographed through the photographing unit 110C and generate a work-to-work photo or a leave-off photo for each recognized area T1, according to the prior art. Instead of recklessly recognizing faces to generate a photo or a photo from work, an administrator can set conditions for creating a specific photo.

To this end, the photo generating unit 111 includes a face recognition part 111a, a face occlusion determining part 111b, a recognition range determining part 111c, a recognition distance determining part 111d, and a photo generating part 111e. .

Here, the face recognition part 111a recognizes the face part of the worker by analyzing the image captured by the photographing unit 110C.

In addition, as shown in FIG. 5 , the face occlusion determination part 111b analyzes the image in the region T1 recognized through the face recognition part 111a to determine the degree of occlusion of the face. By analyzing the part that occupies the face of make it

Specifically, the face occlusion determination part 111b analyzes the image in the area T1 recognized through the face recognition part 111a as shown in FIG. 5 to determine the degree of occlusion of the face F, and determines the recognition area ( T1) Only when the degree of occlusion of my face F is less than or equal to the preset minimum occlusion level, the function of the photo generating part 111e, which will be described below, is activated.

In addition, the face occlusion determination part 111b determines the degree of occlusion of the face, and when the degree of occlusion of the face in the recognition area exceeds a preset minimum occlusion level, the output of notification information to warn to cancel the occlusion of the face. To generate a notification information output request signal for transmission to the notification information display portion (117d) to be set below.

Therefore, the worker takes a face at the time of going to work or leaving the office through the photographing unit 110C to generate a picture to go to work or a picture to leave, so that a process such as updating a reference picture or generating access information and transmission of the management server 120 is performed. In order to do this, first, the wearing means (H), such as a mask or hard hat, must be removed and then the shooting must proceed with a bare face.

In addition, the recognition range determination unit 111c determines the recognition range for the size of the region recognized through the face recognition unit 111a, and is determined to be within a level greater than or equal to the preset reference recognition range minimum value and less than or equal to the reference recognition range maximum value. In this case, the function of the photo generating part 111e, which will be described below, is activated.

In this case, the worker who wants to create a picture to go to work or a picture to leave the office by photographing his or her face at work or leaving the office widens the recognition range by narrowing the distance to the photographing unit 110C, or narrows the recognition range by widening the distance to the minimum value of the preset standard recognition range A worker face recognition area (T1) of a size with a level below the maximum value of the above and standard recognition ranges should be prepared.

Otherwise, the function of the photo generation part 111e is deactivated, so that the creation of a work photo or a leave photo itself does not occur.

In addition, the recognition distance determining part 111d determines the recognition distance for the separation distance between the face part F of the worker in the area T1 recognized through the face recognition part 111a and the photographing unit 110C, Only when it is determined to be within a level less than the set maximum recognition distance, the function of the photo generating part 111e to be described below is activated.

To this end, a separate distance sensor is provided on one side of the photo generating unit 111, and the distance between the face part F of the worker in the area T1 recognized through the face recognition part 111a and the photographing unit 110C Distance can be measured more clearly.

However, the recognition distance determination unit 111d is not limited thereto, and a method of inferring the distance between the photographed worker object and the photographing unit 110C through analysis of the image photographed by the photographing unit 110C may be adopted.

In this case, the worker who wants to create a photo to go to work or a photo to leave the office by taking a picture of his or her face at work or leaving the office, the longer the preset maximum recognition distance in the recognition distance determination part 111d, the longer the face recognition and attendance based on it. A photo or a photo from work may be created.

Finally, the photo generation part 111e is a configuration that generates a work-to-work photo or a leave-off photo for each worker's face part F within the area recognized through the face recognition part 111a, and the active state is continuously maintained. As described above, the degree of occlusion of the face F determined by analyzing the image within the region T1 recognized through the face recognition part 111a through the face occlusion determination part 111b is the preset minimum occlusion. The recognition range for the size of the area recognized through the face recognition part 111a through the recognition range determination part 111c is provided within the level of the predetermined minimum value or more and the reference recognition range maximum value or less. is judged or Maximum recognition distance in which the recognition distance for the separation distance between the face part F of the worker in the area T1 recognized through the face recognition part 111a through the recognition distance determination part 111d and the photographing unit 110C is preset It is activated only in the following cases.

Next, as shown in FIG. 4 , the reference photo storage unit 112 stores at least two or more preset reference photos for each worker's attendance reference photo and departure standard photo, respectively, as shown in FIG. 4 . This is a configuration of a database in which information about the recognition rate of each photo is stored.

Here, the standard photo storage unit 112 stores and manages the standard photo for attendance and the standard photo for leaving. The standard photo for each worker and the standard photo for leaving is identification information (I) including information on the name and nationality of the worker. It is classified and stored and managed according to the standard.

More specifically, the identification information (I), which is the standard for classification of the standard photo for arrival and departure, contains information about the worker's name, a separate ID code, date of birth, resident registration number, phone number, gender, country, etc. Identification by worker is possible through this information.

Therefore, in the reference photo storage unit 112, each storage space 112a is partitioned based on the identification information (I) generated by the initial input by the worker as shown in FIG. 4, and the storage space 112a Reference pictures are stored in the preset number of reference pictures.

Next, the worker determination unit 113 analyzes the attendance photos or exit photos for each worker generated through the photo generation unit 111 and compares them with the attendance reference photos or exit photos stored in the reference photo storage unit 112 . A configuration for identifying and judging workers who want to go to work or leave work. It includes a registration determination part 113a, a worker judgment part 113b, an identification information input interface activation part 113c, a character recognition part activation part 113d, and an identification information generation part 113e.

Here, the registration status determination part (113a) is stored in the reference photo storage unit of the reference photo or reference photo of the corresponding worker through the analysis of each worker's attendance photo or leaving photo generated through the photo generation unit 111. and whether it is registered or not.

Accordingly, the worker determination part 113b is activated when it is determined through the registration determination part 113a that the worker's attendance standard photo or the departure standard photo is pre-stored and registered in the reference photo storage unit 112, Or, it identifies and judges workers who want to leave the office.

In other words, the worker determination part 113b compares the attendance picture or exit picture for each worker generated through the photo generation unit 111 and the reference picture to go or exit from the reference picture stored in the corresponding reference picture storage unit 112. It is ultimately decided whether the worker is the right person or not.

On the other hand, when it is determined that the worker's departure standard photo or the leaving standard photo is not pre-stored and registered in the reference photo storage unit 112 through the registration determination part 113a, the worker determination part 113b is a photo By activating the identification information input interface activation part 113c and the character recognition part activation part 113d by recognizing that the worker corresponding to the attendance picture or leaving picture generated through the generating unit 111 is in the first visit state, the worker After entering the identification information directly or automatically reading the means on which the identification information is displayed through character recognition, the identification information is generated, and the reference picture storage unit ( 112) to be stored.

Specifically, when it is determined that the identification information input interface activation part 113c is not pre-stored and registered in the reference photo storage unit 112, the employee's attendance reference picture or exit reference picture is not registered through the registration status determination part 113a. It is activated so that an identification information input interface capable of inputting a signal for generating identification information of a worker is output and displayed on the display unit 110D.

In this case, the worker may generate identification information by applying touch pressure on the display unit 110D or directly inputting information into the signal input unit 110K based on the identification information input interface output on the display unit 110D. let it be

In addition, the text recognition unit activation part 113d is below when it is determined that the employee's attendance standard picture or exit reference picture is not pre-stored and registered in the reference picture storage unit 112 through the registration status determination part 113a. The character recognition unit 119 to be described is activated.

And the identification information generating part (113e) is input through the identification information input interface activation part (113c) as a signal input for generating the identification information of the worker is made using the output-displayed identification information input interface on the display unit 110D, The identification information of the worker is generated based on the signal, and the reference photo storage unit 112 stores and registers the worker's attendance reference picture or exit reference picture based on the generated identification information.

According to the implementation, the identification information generating part 113e generates identification information of workers based on the characters extracted by the character recognition unit 119 activated through the character recognition unit activation part 113d, and based on the generated identification information It is also possible to register the reference photo storage unit 112 to store the reference photo of the worker at work or the reference photo for leaving the office.

In this regard, the character recognition unit 119 is an OCR-based character recognition module that extracts only characters recorded on an object such as an ID card or card through scanning or image taking, and captures the identification information display means including the worker's identification information. Thus, only the characters displayed on the identification information display means are recognized, and only the characters that are the basis of the identification information are extracted.

Here, the identification information display means is, for example, a resident registration card, a driver's license. It means a passport, a company ID card, etc., and the character recognition unit 119 extracts only the characters in the photographed image so that the identification information generation unit 113e can generate identification information.

To this end, the character recognition unit 119 captures or scans the identification information display means provided by the worker in the seating space to generate an image of the surface on which the identification information of the means is displayed. and a character extraction part 119b for extracting and converting the characters in the generated image using a character recognition technology such as optical character recognition (OCR) to data.

Next, the recognition rate analysis unit 114a is a configuration that analyzes the recognition rate of the attendance photo or the leave photo generated through the photo generation unit. Therefore, it is necessary to extract the recognition rate information of the photo image generated through each shooting and update the reference photo based on it.

Specifically, the recognition rate analysis unit 114a converts the worker face image within the recognition area of the image captured by the photographing unit 110C into the frequency domain using a Fourier transform formula, and then applies a high-pass filter to After excluding the low-frequency region and selecting only the high-frequency region, the recognition rate can be derived through digitization based on the number or range of clear regions.

The recognition rate derivation method through the recognition rate analysis unit 114a as described above corresponds to one example, and is not limited thereto, and it is preferable to perform a batch digitization based on one of various known image recognition rate measurement methods.

Next, the reference photo update unit 114b is a reference photo storage unit 112, the number of reference photos stored in the worker determination unit 113 is determined to identify the worker's attendance reference picture or the recognition rate analysis unit of the reference picture leaving. At the same time, the attendance reference photo or the departure standard photo, which has a low recognition rate compared to the attendance picture or exit photo analyzed through (114a), is deleted, and at the same time, the attendance picture or exit photo analyzed through the recognition rate analysis unit (114a) is displayed as the attendance reference picture or exit standard. update with pictures.

More specifically, as shown in FIG. 4 , the reference photo update unit 114b stores four reference photos as the reference photos for arrival or reference photos when the preset number of reference photos is 4 in the reference photo storage unit 112 . The division 112 is classified and stored based on the identification information (I), and it is analyzed through the recognition rate analysis unit 114a among the employee's attendance standard photo or the departure standard picture identified through the worker determination unit 113. To compare the recognition rate of the departure and departure photos (P5) and the reference photo storage unit (112) based on the identification information (I) stored in the standard photo or reference photos (P1, P2, P3, P4) do.

In this case, the reference photo for arrival or departure corresponding to the third of the reference photo storage unit 112 classified and stored based on the identification information (I) or the reference photo for leaving the office (P1, P2, P3, P4). The recognition rate of the reference photo (P3) is 87, and among the standard photos or photos of the workers identified through the worker determination unit 113, the attendance photo or the leaving photo (P5) analyzed through the recognition rate analysis unit 114a. Since the recognition rate is lower than 90, the third reference photo or reference photo (P3) is deleted, and the photo or photo (P5) analyzed through the recognition rate analysis unit 114a is updated as the reference photo. .

As another example, when the reference photo update unit 114b is in a state in which at least two or more preset number of reference photos are not stored in the reference photo storage unit 112 for each worker's arrival and departure reference photos, the recognition rate analysis unit ( 114a) is stored in the reference photo storage unit 112 along with the information on the recognition rate of the picture to go to work or the picture to leave the office analyzed as the reference picture to go to work or the reference picture to leave.

Next, the sharpness analyzer 115a analyzes the sharpness of the degree of shaking in the face region T1 of the worker recognized through the photo generator 111 among the images captured by the photographing unit 110C.

More specifically, the sharpness analysis unit 115a detects the edge of the image within the face region T1 of the worker recognized through the photo generator 111 among the images captured by the photographing unit 110C. It continuously analyzes image shake information in real time using various techniques such as image differentiation, corner extraction, Hough line transformation, feature point extraction, and image histogram.

If the degree of shaking is excessive, it affects the state of the attendance picture or exit picture based on the image taken through the photographing unit 110C, and the identification result of the worker as well as the management of the worker's access information. Significant problems arise.

Next, the photo generation control unit 115b compares the sharpness analyzed by the sharpness analyzer 115a with a preset minimum sharpness reference value, and controls whether the photo generation unit 111 generates a photo to go to work or a photo to leave.

Specifically, when the sharpness analyzed by the sharpness analysis unit 115a is provided to be greater than or equal to a preset minimum sharpness reference value, the photo generation control unit 115b controls the photo generation unit 111 for the recognized worker's face region for each worker. Activate the function to create work photos or leave photos.

In addition, when the sharpness analyzed through the sharpness analysis unit is provided to be less than a preset minimum sharpness reference value, the photo generation control unit 115b is configured to include a picture of each worker going to work or a picture of leaving the workplace for the face region of the worker recognized by the picture generation unit 111 . Disable the creation function.

Therefore, the function of generating a photo for each worker at work or leaving a photo through the photo generating unit 111 is possible only when the degree of shaking of the image captured by the capturing unit 110C is stabilized.
