Description

Système de reconnaissance d'une personne  Person recognition system
Le domaine de l'invention est celui des systèmes gouvernementaux et concerne plus précisément un système électronique permettant de reconnaître automatiquement une personne, par son aspect physique et plus précisément par la reconnaissance de son visage, de son iris. The field of the invention is that of government systems and concerns more precisely an electronic system for automatically recognizing a person, by its physical appearance and more specifically by the recognition of his face, his iris.
Les systèmes de reconnaissance physique sont classiquement employés dans les aéroports, les ambassades, les écoles, les centres de recherche, et de manière générale, dans tous les lieux où un contrôle d'accès est nécessaire.  Physical recognition systems are typically used in airports, embassies, schools, research centers, and generally in all places where access control is required.
Traditionnellement, un contrôle d'immigration d'une personne dans un aéroport consiste à se présenter à un guichet tenu par un officier d'immigration à qui le voyageur présente son passeport, sa carte d'identité ou tout autre document de voyage. Le douanier, après avoir vérifié que le visage du voyageur qui se présente à lui correspond bien à celui qui figure sur la photographie du passeport (en sus d'avoir vérifié que cette personne n'est pas recherchée), autorise ce voyageur à se présenter dans la salle d'embarquement.  Traditionally, an immigration check of an individual at an airport consists of presenting himself at an ATM held by an immigration officer to whom the traveler presents his passport, identity card or other travel document. The customs officer, after checking that the face of the traveler who comes to him matches the one on the photograph of the passport (in addition to having verified that this person is not wanted), authorizes this traveler to present himself in the departure lounge.
Depuis l'apparition des passeports électroniques, une photographie du voyageur peut être enregistrée dans une puce électronique comprise dans son passeport. Le douanier dispose d'un lecteur apte à lire cette photographie qui s'affiche alors sur un écran. La comparaison de la photographie affichée et du visage du voyageur qui se présente au douanier permet à ce dernier de vérifier l'authenticité du voyageur.  Since the advent of electronic passports, a photograph of the traveler can be recorded in an electronic chip included in his passport. The customs officer has a reader able to read this photograph which is then displayed on a screen. The comparison of the photograph displayed and the face of the traveler who comes to the customs officer allows the latter to verify the authenticity of the traveler.
Afin de limiter la durée des contrôles douaniers et de diminuer le taux d'échec des identifications des personnes, des systèmes de reconnaissance physique électroniques automatiques ont été déployés dans les aéroports. Ces systèmes comportent un sas (une porte d'entrée et une porte de sortie limitant un espace clos) dans lequel le voyageur pénètre. Le sas mesure quelques mètres de long. Lors de l'entrée dans le sas et muni de son document de voyage électronique, le voyageur présente son passeport à un lecteur électronique qui lit la photographie du voyageur qui y est stockée. A proximité de l'obstacle de sortie du sas, une caméra ou un appareil photographique prend plusieurs photographies du visage de la personne qui s'avance dans le sas et compare ces images avec celle lue dans le passeport électronique. Si une des photographies prise par la caméra ou l'appareil photographique est exploitable et correspond à la photographie lue dans le passeport électronique, la personne a été reconnue et la porte de sortie du sas s'ouvre. La personne peut alors sortir du sas. Dans le cas contraire, la personne n'a pas été reconnue et celle-ci est invitée à passer un contrôle traditionnel, tel que mentionnée ci-dessus. In order to limit the duration of customs controls and to reduce the failure rate of person identifications, automatic electronic physical recognition systems have been deployed at airports. These systems include an airlock (an entrance door and an exit door limiting an enclosed space) into which the traveler enters. The airlock is a few meters long. When entering the airlock and carrying his electronic travel document, the traveler presents his passport to an electronic reader who reads the photograph of the traveler who is stored there. Near the exit obstacle of the airlock, a camera or a camera takes several photographs of the face of the person who walks in the airlock and compares these images with the one read in the electronic passport. If one of the photographs taken by the camera or the camera is exploitable and corresponds to the photograph read in the electronic passport, the person has been recognized and the exit door of the airlock opens. The person can then leave the airlock. Otherwise, the person has not been recognized and they are invited to pass a traditional control, as mentioned above.
On connaît, par la demande de brevet WO 2010/045941 , un tel système de reconnaissance physique d'une personne.  Patent application WO 2010/045941 discloses such a system for physically recognizing a person.
Ce système comprend, dans le sas, une caméra mobile montée sur une rampe verticale. Lorsque le voyageur entre dans le sas et se dirige vers la porte de sortie, plusieurs photographies de la personne en mouvement sont prises et la position verticale de la caméra est ajustée pour que celle-ci puisse prendre une photographie de face du voyageur. Ceci est nécessaire du fait des tailles différentes des voyageurs : une photographie d'une personne de 1 ,20 mètre (par exemple un enfant) ne peut pas être prise à la même hauteur qu'une personne qui mesure 2 mètres.  This system includes, in the airlock, a mobile camera mounted on a vertical ramp. When the traveler enters the airlock and heads for the exit door, several photographs of the moving person are taken and the vertical position of the camera is adjusted so that it can take a front view of the traveler. This is necessary because of the different sizes of the travelers: a photograph of a person of 1, 20 meter (for example a child) can not be taken at the same height as a person who measures 2 meters.
Les deux inconvénients principaux de cette solution sont les suivantes : The two main disadvantages of this solution are the following:
- Des éléments mécaniques et électriques sont utilisés pour mouvoir verticalement la caméra (de haut en bas et de bas en haut). Ces éléments (rampe sur laquelle peut se mouvoir la caméra, mécanisme d'entraînement, moteur,...) doivent subir un entretien régulier pour que la caméra soit toujours opérationnelle et puisse toujours prendre, en définitive, une photographie en face du visage du voyageur ; - Mechanical and electrical elements are used to move the camera vertically (from top to bottom and from bottom to top). These elements (ramp on which the camera can move, mechanism of drive, motor, ...) must undergo a regular maintenance so that the camera is always operational and can always take, finally, a photograph in front of the face of the traveler;
- Le déplacement vertical de la caméra prend un certain temps, avant qu'une bonne photographie de face du voyageur ne soit prise. Si le voyageur avance trop vite dans le sas, la caméra n'a pas le temps de se déplacer suffisamment vite pour qu'une photographie de face permettant de le reconnaître soit prise. Le voyageur devra donc reculer dans le sas et avancer à nouveau lentement pour que la caméra puisse se positionner en face de son visage avant de prendre une photographie qui pourra être comparée avec celle figurant dans son passeport électronique. Le dispositif de reconnaissance automatique de personnes perd alors de son intérêt puisqu'il est initialement sensé faire gagner du temps au contrôle migratoire.  - The vertical movement of the camera takes a while, before a good photograph of the traveler's face is taken. If the traveler moves too fast in the airlock, the camera does not have time to move fast enough for a front photograph to recognize it is taken. The traveler will have to step back in the airlock and move slowly again so that the camera can position itself in front of his face before taking a photograph that can be compared with that contained in his electronic passport. The automatic recognition of persons device then loses its interest since it is initially supposed to save time to migratory control.
La présente invention a notamment pour objectif de remédier à ces inconvénients.  The present invention is intended to overcome these disadvantages.
Plus précisément, un des objectifs de l'invention est de fournir un système de reconnaissance physique d'une personne alliant fiabilité, absence d'entretien et permettant de reconnaître physiquement bien plus rapidement une personne (par exemple un voyageur dans un aéroport) que dans l'état de la technique précité. More specifically, one of the objectives of the invention is to provide a physical recognition system of a person combining reliability, lack of maintenance and to physically recognize a person much faster (eg a traveler in an airport) than in the state of the art aforementioned.
Cet objectif, ainsi que d'autres qui apparaîtront par la suite, est atteint grâce à un système de reconnaissance d'une personne, le système comprenant des données biométriques de référence relatives au visage de la personne, le système comprenant des moyens de capture d'images du visage de la personne ainsi que des moyens de comparaison des données biométriques de référence avec les images issues des moyens de capture d'image pour authentifier ou non la personne.  This objective, as well as others that will appear later, is achieved through a system of recognition of a person, the system comprising reference biometric data relating to the face of the person, the system comprising means of capturing facial images of the person as well as means for comparing the reference biometric data with the images from the image capture means for authenticating or not the person.
Selon l'invention, les moyens de capture d'images sont constitués de plusieurs caméras fixes disposées verticalement les unes par rapport aux autres, afin de prendre des photographies à différentes hauteurs de la personne. Les caméras sont, chacune, aptes à prendre des photographies successives de la personne. Au moins les photographies exploitables sont comparées au fur et à mesure qu'elles sont prises avec les données biométriques de référence par les moyens de comparaison.  According to the invention, the image capture means consist of several fixed cameras arranged vertically relative to each other, in order to take photographs at different heights of the person. The cameras are each able to take successive photographs of the person. At least the exploitable photographs are compared as they are taken with the reference biometric data by the means of comparison.
Avantageusement, les photographies exploitables sont constituées par des photographies du visage de la personne.  Advantageously, the exploitable photographs consist of photographs of the person's face.
Dans un autre mode de mise en œuvre, les photographies exploitables sont constituées par des photographies de l'iris de la personne.  In another mode of implementation, the exploitable photographs are constituted by photographs of the iris of the person.
Préférentiellement, le flux des photographies est affiché sur un écran en face duquel la personne est invitée à positionner son visage.  Preferably, the flow of photographs is displayed on a screen in front of which the person is invited to position his face.
Avantageusement, l'écran comprend un système d'assistance au positionnement du visage de la personne.  Advantageously, the screen comprises a system for assisting the positioning of the person's face.
Les moyens de comparaison sont préférentiellement reliés à un mécanisme d'ouverture d'une porte de sortie.  The comparison means are preferably connected to a mechanism for opening an exit door.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description suivante d'un mode de réalisation de l'invention, donné à titre illustratif et non limitatif, et de la figure unique annexée représentant un système selon la présente invention.  Other features and advantages of the invention will appear on reading the following description of an embodiment of the invention, given by way of illustration and without limitation, and of the single appended figure representing a system according to the present invention. .
Le système de la figure est destiné à reconnaître (authentifier) une personne The system of the figure is intended to recognize (authenticate) a person
10, de part son apparence physique. Cette reconnaissance peut consister à reconnaître son visage, une partie de son visage ou son iris par exemple. 10, because of his physical appearance. This recognition may consist of recognizing his face, a part of his face or his iris, for example.
Le système comporte des données biométriques de référence. Ces données biométriques de référence peuvent être stockées dans une base de données (une photographie du visage de la personne y a préalablement été stockée) ou avoir été lues par un lecteur (par exemple un lecteur de document de voyage électronique) sur lequel la personne aura préalablement déposé son document, à des fins d'authentification. The system includes biometric reference data. These biometric reference data can be stored in a database (a database photograph of the person's face has been previously stored) or have been read by a reader (eg an electronic travel document reader) on which the person has previously filed his document, for authentication purposes.
Dans le cas de l'utilisation d'un lecteur, la personne porte sur elle un document dans lequel sont enregistrées ces données biométriques de référence et ces données sont lues par le lecteur.  In the case of the use of a reader, the person carries on it a document in which these biometric reference data are recorded and these data are read by the reader.
Le système a pour but d'authentifier la personne pour lui laisser (ou non, en cas de non authentification) accès à un bâtiment, une salle d'enregistrement d'un aéroport, une salle de concert, un stade...  The system aims to authenticate the person to let him (or not, in case of non-authentication) access to a building, an airport registration room, a concert hall, a stadium ...
De même que dans l'état de la technique, des moyens de capture d'images du visage de la personne ainsi que des moyens de comparaison des données biométriques de référence avec les images issues des moyens de capture d'image pour authentifier ou non la personne sont prévus.  As in the state of the art, means for capturing images of the person's face as well as means for comparing the reference biometric data with the images from the image capture means to authenticate or not to authenticate the image. no one is expected.
Selon l'invention, ces moyens de capture d'images sont constitués par plusieurs caméras fixes 1 1 à 15 disposées verticalement les unes par rapport aux autres (par exemple sur un rail) afin de prendre des photographies à différentes hauteurs de la personne 10.  According to the invention, these image capturing means are constituted by several fixed cameras 1 1 to 15 arranged vertically relative to each other (for example on a rail) in order to take photographs at different heights of the person 10.
Une première caméra 1 1 est ici située à 210 cm du sol, une seconde 12 à 185 cm, une troisième 13 à 160 cm, une quatrième 14 à 135 cm et une cinquième 5 à 1 10 cm. Les caméras sont donc superposées verticalement.  A first camera 1 1 is here located 210 cm from the ground, a second camera 12 to 185 cm, a third 13 to 160 cm, a fourth 14 to 135 cm and a fifth 5 to 1 10 cm. The cameras are thus superimposed vertically.
Chaque caméra 1 1 à 15 est apte à prendre des photographies successives de la personne 10. En pratique, chaque caméra filme la personne 10 qui s'est soit positionnée en face d'elles, soit qui se déplace dans leur direction. Une photographie de chaque film est sélectionnée à périodes régulières, par exemple toutes les 50 ms, ce qui permet d'obtenir une pluralité de photographies de la personne, prises à différentes hauteurs et éventuellement distances. Certaines de ces photographies sont bien sûr inexploitables (sujet trop éloigné, photographie floue, visage hors champ, sujet qui a tourné ou baissé la tête,...). L'invention propose de comparer au moins les photographies exploitables (voire toutes les photographies prises par les caméras 1 1 à 15), et ce au fur et à mesure qu'elles sont prises, avec les données biométriques de référence. Ces comparaisons sont effectuées, de même que dans l'état de l'art, par des moyens de comparaison reliés à la base de données et/ou au lecteur prévu à l'entrée de la zone de contrôle (par exemple un sas). Les champs de vision des caméras 1 1 à 15 sont respectivement référencés 16 à 20. Ces champs de vision se superposent et permettent donc d'obtenir de façon presque certaine au moins une photographie exploitable de la personne 10. Each camera 1 1 to 15 is able to take successive photographs of the person 10. In practice, each camera films the person 10 who has positioned himself in front of them, or who moves in their direction. A photograph of each film is selected at regular periods, for example every 50 ms, which makes it possible to obtain a plurality of photographs of the person, taken at different heights and possibly distances. Some of these photographs are of course unusable (subject too distant, photography blurred, face off, subject who turned or lowered his head, ...). The invention proposes to compare at least the exploitable photographs (or all the photographs taken by the cameras 1 1 to 15), and as they are taken, with the reference biometric data. These comparisons are made, as in the state of the art, by comparison means connected to the database and / or to the reader provided at the entrance of the control zone (for example an airlock). The fields of vision of the cameras 1 1 to 15 are respectively referenced 16 to 20. These fields of view are superimposed and thus allow to obtain almost certainly at least one exploitable photograph of the person 10.
Si l'une des photographies correspond aux données biométriques, la personne 10 est autorisée à passer : elle a été authentifiée. Une porte de sortie peut alors s'ouvrir par exemple (les moyens de comparaison sont reliés à un mécanisme d'ouverture d'une porte de sortie).  If one of the photographs corresponds to the biometric data, the person 10 is authorized to pass: it has been authenticated. An exit door can then open for example (the comparison means are connected to an opening mechanism of an exit door).
Si la personne 10 n'a pas été authentifiée dans une durée paramétrable (personne ayant tourné la tête par exemple pendant les prises des photographies), la personne 10 est considérée comme étant non authentifiée et invitée à quitter le sas pour un contrôle manuel.  If the person 10 has not been authenticated in a configurable time (person having turned their head for example during the taking of photographs), the person 10 is considered to be unauthenticated and invited to leave the airlock for manual control.
Un écran digital est associé à chacune des caméras. Un seul écran est actif à la fois, l'écran choisi étant celui le plus proche de l'axe horizontal des yeux. Ces écrans servent d'invite au voyageur (en comportement normal, un voyageur va instinctivement porter son regard sur une image mobile face à lui), et d'aide au positionnement du visage grâce à un cadre de couleur rouge ou verte indiquant l'exploitabilité des images capturées. Dans la figure, cet écran est l'écran 23 qui est situé sous la caméra 13. La caméra 13 est effectivement celle qui se trouve à hauteur du visage de la personne 10.  A digital screen is associated with each of the cameras. Only one screen is active at a time, the selected screen being the one closest to the horizontal axis of the eyes. These screens serve as an invitation to the traveler (in normal behavior, a traveler will instinctively look at a moving image in front of him), and help the positioning of the face with a red or green color indicating the operability captured images. In the figure, this screen is the screen 23 which is located under the camera 13. The camera 13 is actually the one at the height of the person's face 10.
L'écran 23 peut afficher le flux des photos prises par la caméra 13 ou alors la séquence filmée par la caméra 13. Le visage de la personne 10 peut être photographié par la caméra 13 avec précision une fois que cette dernière a positionné son visage en face de l'écran 23.  The screen 23 can display the flow of the photos taken by the camera 13 or the sequence filmed by the camera 13. The face of the person 10 can be photographed by the camera 13 accurately once the latter has positioned his face in face of the screen 23.
Dans le cadre de l'invention, les photographies exploitables sont constituées par des photographies du visage de la personne 10. Des logiciels de reconnaissance faciale sont utilisés. Par « visage de la personne », on entend également toute reconnaissance physique, par exemple de celle de l'iris d'une personne.  In the context of the invention, the exploitable photographs consist of photographs of the face of the person 10. Facial recognition software is used. By "face of the person" is also meant any physical recognition, for example that of the iris of a person.
L'invention permet de vérifier l'authenticité d'une personne bien plus rapidement que dans l'état de la technique, grâce à cette pluralité de caméras aptes à prendre plusieurs photographies d'une personne à différentes hauteurs, ces photographies étant comparées aux données biométriques de référence au fur et à mesure qu'elles sont prises. De plus, l'invention ne comportant pas de parties mobiles pour la capture d'images, la robustesse du système est améliorée (poids, freins, motorisation, ...). The invention makes it possible to verify the authenticity of a person much more quickly than in the state of the art, thanks to this plurality of cameras capable of taking several photographs of a person at different heights, these photographs being compared with the data reference biometrics as they are taken. In addition, the invention does not include any parts mobile for the capture of images, the robustness of the system is improved (weight, brakes, engine, ...).
