Description

Method and Vorrichtun g for identification and recognition of living things and / or articles

The invention relates to a method and an apparatus for identification and recognition of living things and / or articles according to the preamble of claim 1 and the preamble of claim 31st

Such methods and devices are used everywhere, where for example the identity of a person must be detected in order for example. to forgive, justifying to g angs supply an access or. These include ATMs, computer workstations, access to farms, security areas or lockers. are known methods and devices in which identity cards, chip cards are assigned with or without personal identification number (PIN) or password. proves to be disadvantageous in these known methods and devices that a special agent for the identification of the person must always be carried. If this means forgotten, access or access is not possible. If the agent is stolen by an unauthorized person, then this access or access can provide. In order for these known processes for the user consuming and in their handling are not reliable.

Furthermore, methods and devices are known (US 5,067,162), in which resorted to identify a person on the fingerprint data. Of the dermal ridges of a finger of the person to be identified a picture is taken and saved them. For recognition of that person another recording is made and compared it directly with the stored first recording. If the two images match, the person is deemed to be identified. It proves disadvantageous that the test is relatively expensive due to the direct comparison of the two images here. Therefore, the test takes a correspondingly long and takes in which the method by leading computer a lot of memory. In addition, the recognition or identification of an individual fails when have the dermal ridges, for example, due to injury, changed.

In contrast, the inventive method having the characterizing features of claim 1 and the apparatus according to the invention with the characterizing features of claim that firstly a reference image is created, 31 the advantage is in which a predetermined portion of the to be identified living organism or to be identified object by an image pickup apparatus is recorded. characteristic features and their position are then determined and stored as a reference data set on a memory from the reference image. For the identification or recognition of the subject or of the object is recorded a s B il DAU ooting device from the predetermined portion using a Ide s ti n fi zi ng ERU s bi ld. Then the identifying image is the presence of features and Po sitions the reference data set examined. the characteristics of finally find functions at the specified Posi in identifying image again, the creatures or the subject in question is identified as valid. the characteristics, however not find or at other positions, so the animal or object is deemed not to be identified. The number of data stored in the reference data set characteristics may vary depending on the application. It depends on the complexity of the recorded structures to be identified creature or object, on the desired accuracy of the identification and of the possibilities offered by the image capture device. The inventive method and the inventive device work quickly and reliably, since the number of data to be stored is small, and no direct comparison between the reference image and identifying image takes place, but only the data of the reference data set in the I denti fi zierungsbildgesuchtwe gestures. Of the

Identification is in progress so rapidly and without increased memory requirements. As suitable for identifying portions of the living creature concerned or of the object in question, for example, parts of the surface of the article or special parts of the skin of the animal are suitable. In a person, this example the fingers or face may be because they are rarely covered by clothing and thus always available for test purposes are available.

According to an advantageous embodiment of the method according to the invention the relative positions of the features are determined to each other and stored in the reference data set. The zero point of the relevant reference system can thereby be placed for example in the position of the features. This facilitates finding the features in the identifying image.

According to a further advantageous Au sgestaltung of the inventive method takes into account the existing laws in the section or regularities in the identification of the animal or the object. In this way, organisms can be identified at low damage and recognized even in minor injuries or deformities of their body parts or objects.

According to a further advantageous embodiment of the inventive method, the reference data set is adapted to changes in the characteristics and their position. So chronic changes or ernde counter s tänden andau changes can be considered in people. An appropriate examination of the reference data set can be carried out at each identification process.

According to a further advantageous embodiment of the method of the invention a plurality of different types of features are used as reference data set. Should there be, for example, in the section to be identified around the finger of a person, such as topological or morphological structures may be used as a characteristic species. These include, for example, dermal ridges or glands such as tallow or sweat glands. The use of multiple feature types increases the reliability of the method, particularly in the identification of portions which are changed by damage or injury in respect of individual features.

According to a further advantageous embodiment of the inventive method a plurality of features to be converted into numerical values ​​and combined to form a value. In this way, the amount of data can be reduced and the identification process to be accelerated.

According to a further advantageous embodiment of the inventive method a plurality of features of a certain type are combined to form a pattern or a pattern group. In this way, multiple people or objects can be examined for matching features and divided into groups.

According to a further advantageous embodiment of the method of the reference data set in memory to enter additional data (personal identification number, data on a data carrier) as a search help for the search. This speeds up the identification process further. According to a further advantageous embodiment of the inventive method for creating the reference data set and identifying of the animal or the object several different numerical methods are used simultaneously. This leads on the one hand to an increased flexibility and speed of the method and the apparatus. On the other hand thereby the interference, distortion, or copy of the method or the apparatus becomes difficult, thereby increasing the safety and reliability.

According to a further advantageous embodiment of the method the Trelly method is used to create the reference data set and identifying of the animal or object in addition to other numerical method used.

In a further advantageous embodiment of the inventive method, the wavelet method is used to create the reference data set, and to search the features of the reference data set in the identifying image next to other numerical methods. Here, in particular the possibilities of Datenkomprimi augmentation, the B ildzu s ammens nuation, the reconstruction of image defects, recognizing and selecting traits and the exploitation of property that phase information is transmitted exploited. In addition, M ö ö glichkeitenzur e rh hungder

According to a further advantageous embodiment of the method to be identified animal is an individual. According to a further advantageous embodiment of the method according to the invention characteristic portions of the epidermis to be used for the identification of the person as characteristics for the individual. These include, for example, dermal ridges, sweat and sebaceous glands and their openings, vessels, particularly blood vessels and their movements due to the pulse beat. It is particularly advantageous here to indicate the positions of the openings relative to the skin glands strips. In a temporally resolved recording also the registering of dynamic effects such as pumping or flow movements or changes in diameter of the vessels, and their use for identification are possible.

According to a further advantageous embodiment of the method, the portion of the person to be identified is facing away from the nail side of the finger. This side of the finger of fingerprint fingerprints are recorded and evaluated in the known processes. In contrast to the known fingerprinting methods are not only detected in the invention, the characteristics of the dermal ridges and evaluated, but also more in the epidermis existing structures such as sweat or sebaceous glands or vessels. With the use of image pickup devices with a correspondingly high sensitivity and small Stukturen as glands or vessels or Strukuren can be detected under the skin surface and used for identification. The method may also provide for the recording and evaluation of several fingers. Thus, the recognition rate can be increased. In addition, the other fingers are in an injury to a finger for identification available. Darüberhinau s can bring different intentions of the person to express different fingers. According to a further advantageous embodiment of the method, the portion of the person to be identified is the face or parts of the face. As features the properties of the epidermis, or the position or color of the eyes, the position of the nose, the shape of the mouth, the position of folds of skin or the shape of the face can also be used here.

According to a further advantageous embodiment of the method the natural heat radiation of the human body is taken to create the reference image and to identify the person by the image pickup device. Receiving the reference or identification image can be done without j ny illumination or lighting of the relevant body part. It works even in total darkness.

The process of the present invention may be an integrated part of the authorization check. During the authorization may be an access or access authorization. These are used for example in automatic teller machines, staff entrances or security areas application. Due to the identification of a person authorized person is not given to serve, for example, a particular device or open a door. An authorized person may also assign additional permissions to third parties. Certain groups of people are entitled to different actions, so that a decision tree can be created for the system. Here, the mechanisms of the Petri net may apply. Permissions can also be combined or divided or withdrawn subsequently. The method may be integrated in a process control or monitoring language or in an instrumentation, or data flow representation language. Examples include the software tools from National Instruments such as Labview, LabWindows / CVI or Bridgeview. The method can be applied, for example, when buying in the cash payout in a database access or an access control.

According to a further advantageous embodiment of the invention, the permission can be spatially and / or temporally restricted. This is for example advantageous when a person concerned is absent for a certain time at a certain place. It may be a hotel, which inhabits the person on their holidays or a hospital or a sanatorium, which seeks the person to recovery. For example, Upon completion of the stay, the assigned permissions can complete and, for example, all payments made by the person will be charged. The external memory on which the reference data are stored, for example, can be integrated into one used by the person in time during their stay in key or a pin. It can also be provided that the reference data are stored in a central storage or a computer network, so that identification no additional disk must be carried. As search help a personal identification number or other additive can be awarded.
