Abstract

The invention relates to a door installation comprising at least one closeable and openable door, a door drive, and a door control unit for automatically actuating the drive, wherein at least one camera is provided for detecting a person in the door-passing area, and is connected to the door control unit via a data connection, said door control unit comprising means for biometric facial recognition and authentication of the detected person.

Description

gate system

The invention relates to a door system with at least one closable and openable door, a door drive and a gate control for automatic Antriebssbetäti- supply.

Frequently, commercially available doors, in particular garage doors, can be actuated either via a stationary operating element, such as a key switch, or else by means of a radio switch. In addition, there are so-called "keyless" systems that enable user verification by entering a number code on a corresponding control panel or by means of fingerprint sensors. It is common to all these systems that a specific manual user action via the respective input device is required for authentication. This often proves to be disadvantageous, either because the user has no hand free or weather-related by appropriate clothing (eg gloves) the input is not readily possible.

As a further alternative, an authentication by means of RFID tags is known. However, if the user forgets to carry the transmitter with them, opening the gate is no longer possible. The object of the present application is to provide an alternative solution for the identification and authentication of users for operating a door, in particular garage door, show by which the problem described above can be solved or at least reduced.

This object is achieved by a door system according to the features of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

According to the invention, it is proposed to expand a generic gate system by at least one camera for detecting a person in the gate passage area or in a suitable position in the gate area. By means of a data connection of the camera for gate control, a transmission of the image data from the camera to the gate control is ensured. The data connection can be wired or wireless. The latter optionally allows more degrees of freedom in the placement of the camera at a suitable location.

The door control of the door system further comprises means for biometric facial recognition in order to enable identification and authentication of the detected person on the basis of his face. As a result, the gate controller analyzes the received camera images to detect the face of the person being photographed. While the identification involves merely detecting the person being detected as a system aware person, the authentication involves further steps to verify that the identified person is authorized to operate the door, i. to open or close.

The solution according to the invention requires no separate interaction of the operator, any action with the hands becomes unnecessary. It is also no longer necessary to carry mobile operating or recognition features (transmitting unit). Instead, it is sufficient for the person in question to enter the camera's coverage area. If necessary, the operator must allow a close-up of his face. According to an advantageous embodiment, it makes sense for the identification and authentication of the person if an identification and / or authentication is carried out to match the recognized face with personal image data stored in an image memory. As a rule, significant facial features are measured in biometric procedures. These measured data can then be compared with stored reference values of the respective persons. With the image data, additional data for the authorization of the person can be stored. For a verification, however, it may be sufficient if only image data is available for the recognized face, ie the person detected by the camera is known to the system and can be successfully identified.

The image memory can be part of the door control or door system. Alternatively, an external image memory can be accessed by means of data connection through the gate control. In a further preferred embodiment, the means for facial recognition may also be outsourced, i. In such a case, the image data from the gate controller is forwarded to an external face recognition server. Based on the server feedback, the gate controller can then take the necessary control measures. The data connection to an external memory or a face recognition means can take place by means of a wireless connection, such as WLAN, mobile radio, etc., or else by wire-bound communication.

It is advantageous if the personal image data within the image memory can be linked or linked with one or more control commands for the door drive. This allows a personal control of the door drive. Such control commands may include, in addition to simple opening and closing commands of the door, one or more conditions for conditional control command execution.

In this context, it is conceivable, for example, to associate one or more individual control commands with corresponding time windows, by one Time-limited command execution can be defined. In practice, for example, a door opening for certain persons could only be released and triggered within a valid time window, while the door access remains locked outside the time window. Other people, however, can be accessed around the clock gate access. Not only a daytime-dependent control is possible, but also date-dependent control.

The configuration and subsequent adaptation of corresponding time windows can be made possible for example via a special configuration access of the door control.

In addition to the means for face recognition, the door control may additionally comprise at least one means for detecting and / or interpreting a graphic code within the provided camera images. With the aid of such a code, further information can be fed to the door control at the same time, either to increase the security during the authentication of the detected person or else to synchronously feed in a special control command. For example, a person may additionally wear a graphic code visibly. If the person is identified by the door control and if necessary authenticated, the door control can additionally execute the recognized graphic code. The use of a so-called QR code is conceivable. It is also conceivable to use such graphic codes for training a new person. In this case, the code is used to signal to the door controller that the person carrying the code is authorized, even if the associated data in the image memory show the opposite. After successful interpretation of the code in the image memory, the door control can release already existing data for the recognized person for the door opening or by means of the face recognition for the first time create a corresponding memory entry to the person with the recognized facial features from the executed face recognition.

In addition, the use of graphical codes offers further possibilities. It is also conceivable that using the graphic code, the regular for the Torsteuerung necessary identification and authentication by means of facial recognition is at least temporarily disabled. For example, it is conceivable to enable a control command for person-independent door opening by means of a corresponding graphic code. If the code is successfully recognized, the gate can be opened or closed independently of the person detected.

For security reasons, it makes sense to provide such codes with limited validity, especially in terms of time and / or frequency. In terms of frequency, in this context, the code is valid only for a limited number of gate operations. Corresponding information on the validity can also be stored in the memory of the gate control or be included in the code itself. This makes it possible that an individual code is only suitable for a single activation or door opening of the gate, preferably only within a fixed predetermined time window.

According to a further advantageous embodiment of the invention, it can be provided that the means for facial recognition can also detect one or more gestures of the detected user. Such a gesture recognition can be done, for example, by temporal analysis of a chronological image sequence of the camera. The possibility of gesture recognition creates the prerequisite for an extended control of the door drive. In addition, the gesture recognition can also be used to improve the simple door control, since the operator can express expressly his desire to control the door drive by means of the gesture control and misopenings due to a random presence of the person in the detection area of the camera can be purposefully avoided. Against this background, it makes sense if a gate operation is carried out by the gate control only if the detected person is identified and authenticated by means of the face recognition and additionally actually executes a gesture associated with the person in the memory of the gate control and by the person Gate control is detected correctly. For easy commissioning and subsequent configuration of the door system, it is particularly useful if the door control provides at least one communication interface for a configuration access. Such access can ideally be done by means of an external programming device, for which commercially available smartphones, tablets or notebooks can be used. It is also conceivable to integrate the gate control by means of the communication interface into an existing network, in particular a LAN network.

For example, the configuration access can be used to access the corresponding image memory in order to be able to define individual control commands for the individual persons. It is also conceivable to select one or more gestures that can be linked to corresponding control commands or personal data or image data. In sum, the configuration access allows the easy release of persons who are to be authorized for the gate control.

According to a further advantageous embodiment of the invention, the means for facial recognition allows adjustment of a so-called coincidence factor. By means of the matching factor, the degree of the necessary agreement of the detected face with the stored image data in the memory can be defined. This allows the owner of the door himself to determine the relationship between the security and reliability of the face recognition. A high matching factor requires as exact a match as possible, which may increase the frequency of erroneous detection processes, in particular under difficult light or weather conditions or in the case of a certain occultation of facial areas. For example. The reliability of the detection could be increased by reducing the matching factor during difficult light or weather conditions or in the cold season.

The gate control could provide for manual adaptation of the match factor by the user, for example via the already mentioned configuration interface. However, it is alternatively or additionally conceivable that the door To equip the controller with suitable logic for automatically adjusting the matching factor. This logic could automatically adjust the match factor depending on the weather and / or lighting conditions. Also, a daytime and / or season-dependent automatic adjustment of the matching factor is conceivable.

In a preferred embodiment, the gate control is configured to record successful access attempts over a certain period of time. Only successful, only unsuccessful or all access attempts can be recorded. The combined storage of access attempts together with image data of the detected persons is also conceivable, whereby the door system plays the role of a surveillance camera in an abuse attempt.

The operation of the door system does not necessarily have to be reduced to face recognition. At the same time, conventional operating elements such as radio remote controls, key switches, etc. can be supported. Corresponding control elements can either be connected directly to the door operator or to the door controller. It is also conceivable support of mobile devices, such as smartphones, tablets, etc., as controls.

Further advantages and properties of the door system according to the invention will be described in more detail below with reference to the exemplary embodiments illustrated in the figures. Show it:

Figure 1: a sketch of the door system according to the invention to illustrate the basic idea of the invention.

FIG. 2 shows the door system according to FIG. 1 with an optional interface for the configuration access.

Figure 3: the gate system of Figure 1 with optional extension to a

Code recognition. Figure 4: the gate system of Figure 1 with optional extension of a gesture recognition.

FIG. 1 shows the door system 17 according to the invention with the actuatable roller door 18. Although the exemplary embodiments described show a roller door 18, the core idea of the invention is not limited to the type of door shown, but rather can be used with all door types.

The door control 14 is connected via a control line 16 with the door drive, not shown, for actuating the door 18 in connection. Furthermore, a suitable camera 12 is placed in the gate area and records in front of the gate person. The type of camera and the orientation of the camera 12 are chosen so that it is possible to obtain images of the facial area 11 of the person 10 present in the detection area which are sufficiently high-quality.

Via a data link, the camera 12 delivers captured image data to the gate controller 14 equipped with suitable biometric facial recognition means. The data connection between the camera 12 and the Torsteue- tion 14 may optionally be wireless or wired. In the gate control 14, the recorded face 11 of the person 10 is compared with the biometric data within the image database 15. In case of a match, the person 10 can be identified and their authorization verified. If the test is positive, the door controller 14 can send an opening / closing command via the control line 16 to the door drive of the door system 17 in order to trigger the opening / closing of the door 18.

Not only image data are contained in the image memory 15 of the door control 14, but also individual-individual control commands which are to be executed by the door controller 14 or the door drive if the person 10 is identified and authenticated accordingly. Such control commands can not only contain simple opening or closing commands, but also much more complex control systems. tasks that may be linked to certain conditions. Theoretically, the opening degree and / or the opening speed could also be controlled individually by means of such control commands.

In FIG. 2, a communication interface 20 for door control 14 is indicated by way of example, via which access to the door control 14 by means of an external device 19 is made possible. The interface 20 not only enables the targeted control of the door drive by means of a device 19, but also serves as a configuration access to the door control 14, via which, for example, the administration of the image memory 15 is possible. Thus, for example, image data for person identification and / or verification can be transmitted or processed. Also, specific control commands or conditions associated with the image data may be set or manipulated.

It is also conceivable to associate the control commands stored in the door control 14 with time windows so that a release of persons 10 is only possible within a time window, for example via the programming device 19. This inclusion of conditions allows for conditional control commands, which can increase the security of the system. Scenarios are conceivable that unlock a gate access, for example, only on weekdays. Of course, more specific time periods can be set for certain people. For example, a domestic help could be allowed access only on Tuesdays and Thursdays between 10 and 12 o'clock.

FIG. 3 indicates a possible extension of the door system, according to which the release of individual faces 11 from persons 10 is supported by a printed data code 22 printed out and visible to the camera 12. Such a data code 22 would be stored as an instruction together with the face 11 in the door control 14 and in the future would allow door opening. For example. could be trained with the help of the code 22 new people in the door control 14. Such a code 22 could also serve as a one-time, possibly person-independent release. Such a one-time data code would only be valid for a one-time door opening, subsequent opening attempts are rejected. In practice, a postal or parcel delivery could be conveniently realized by sending a data code, which the messenger can print out and keep in the camera. The garage then serves as a protected storage location in the absence of the recipient.

Furthermore, such a one-time code could optionally be combined with a time slot. The validity of the code could thereby be restricted specifically to a time window, i. the code would not become valid until the time window was reached and be invalid after the time window has passed. The necessary information of the time window and the assignment to the code are likewise stored in the memory 15 of the door control.

As a further feature of comfort, it is proposed to carry out a release of a person 10 from a mobile terminal. Here, the required image is first entered in the database 15 with a blocking note, which could then if necessary be removed by remote access, in particular via the interface 20. The customer benefit here is the convenient release of people 10 from a distance, so that no release must take place directly on site.

In addition, the quality of identification of a person 10 may vary according to his or her face 11 (ambient light) or seasonally (clothing). A reduced quality of the camera recording leads to falsely ascertained differences between the recorded face 11 and the associated image data in the memory 15 of the door control 14, so that unsuccessful access attempts by a person 10 authorized per se can occur. This problem can be addressed by introducing a match factor. The matching factor thereby dynamically determines the necessary correspondence between the recognized facial features and the stored image data. For example, it is conceivable to reduce the necessary 100% to just 70% mood to cope with daily or seasonal problems. It can be particularly advantageous if the modification of the matching factor is set automatically by the gate control as a function of the ambient conditions.

If an authorized person 1 looks into the camera 12, then an intended opening pulse is sent from the gate control 14 to the gate system. Under certain circumstances, this can lead to unwanted door openings, provided that the person 10 only happens to be in the door area, but is not interested in a door opening. This problem is addressed by the introduction of additional gesture recognition. In addition to a successful identification and verification of the person 10 by means of face recognition, this must also perform the stored in the memory 15 gesture.

Accordingly, the gate controller 14 is provided with an appropriate gesture recognition means, which can identify and recognize gestures performed by timing and analyzing sequential camera images. As a gesture, for example, a defined head movement from bottom to top or laterally from left to right would be possible, as indicated by FIG.

As an additional extension, it is conceivable to log the accesses with and without an image in order to prevent misuse or to clarify a crime. Such a record of access attempts must then comply with the local data protection regulations.

As a further security feature, it is also proposed that with a system which is registered in the home network (bullet point: smart home), likewise registered cell phones can be used to release the gate system, since it is only sensible and possible to perform an opening.
