[13] As a variant, the display device, and possibly also the data processing device, are arranged to be placed in a fixed manner, in a building or an outdoor courtyard for example.
[14] Selon l’un des aspects de l’invention, le dispositif de traitement est agencĂ© pour faire le diagnostic de maniĂšre automatique, sans une intervention humaine. [14] According to one of the aspects of the invention, the processing device is arranged to make the diagnosis automatically, without human intervention.
[15] Du fait d’un traitement automatique, l’invention permet un diagnostic rapide et/ou un dĂ©pistage massif permettant un retour au travail ou un dĂ©confinement plus rapide. [15] Due to automatic processing, the invention allows rapid diagnosis and/or massive screening allowing a return to work or faster deconfinement.
[16] Selon l’un des aspects de l’invention, le dispositif d’acquisition de donnĂ©es d’examen est agencĂ© pour permettre des mesures sans contact et Ă  distance de sĂ©curitĂ©, de signaux vitaux et d'imagerie thermique et visible sur la personne Ă  examiner. [16] According to one of the aspects of the invention, the examination data acquisition device is arranged to allow non-contact and safety distance measurements of vital signals and thermal and visible imaging on the person to examine.
[17] Le systĂšme selon l’invention utilise ainsi avantageusement la fusion de mesures sans contact et Ă  distance de sĂ©curitĂ©, de signaux vitaux et d'imagerie thermique et visible. [18] Selon l’un des aspects de l’invention, l’unitĂ© d’intelligence artificielle est agencĂ©e pour utiliser un modĂšle de diagnostic basĂ© sur l'intelligence artificielle et nourri par un nombre raisonnable de mesures cliniques. [17] The system according to the invention thus advantageously uses the fusion of measurements without contact and at a safety distance, of vital signals and of thermal and visible imaging. [18] According to one of the aspects of the invention, the artificial intelligence unit is arranged to use a diagnostic model based on artificial intelligence and fed by a reasonable number of clinical measurements.
[19] L’invention, du fait d’un Ă©quipement relativement lĂ©ger, permet notamment un dĂ©ploiement facilitĂ© d’hĂŽpitaux de campagne en soutien aux populations. [19] The invention, due to relatively light equipment, notably allows easy deployment of field hospitals in support of populations.
[20] L’invention permet de rĂ©alisation des diagnostics de maniĂšre mobile. Sa mise en place, par exemple Ă  l’aide d’une camĂ©ra thermique, un capteur de mesure physiologique tel qu’un radar et un ordinateur personnel portable, est facile. L’invention permet son implantation rapide sur tout un territoire. [20] The invention allows diagnostics to be carried out in a mobile manner. Its implementation, for example using a thermal camera, a physiological measurement sensor such as a radar and a portable personal computer, is easy. The invention allows its rapid implementation throughout a territory.
[21] Selon l’un des aspects de l’invention, le dispositif d’acquisition comprend un radar pour acquĂ©rir des donnĂ©es relatives aux signes vitaux de la personne, une camĂ©ra thermique pour les mesures de tempĂ©rature fournissant des donnĂ©es de tempĂ©rature, et une camĂ©ra fonctionnant dans le spectre visible pour la caractĂ©risation de la personne testĂ©e fournissant des donnĂ©es caractĂ©risation de la personne. [21] According to one of the aspects of the invention, the acquisition device comprises a radar to acquire data relating to the vital signs of the person, a thermal camera for temperature measurements providing temperature data, and a camera operating in the visible spectrum for the characterization of the person tested providing data characterization of the person.
[22] Selon l’un des aspects de l’invention, le dispositif de traitement de donnĂ©es est agencĂ© pour faire tourner un algorithme de diagnostic basĂ© sur une fusion des donnĂ©es vitales, notamment un rythme respiratoire, une amplitude de respiration, un temps d'inspiration et d'expiration, un rythme et arythmie cardiaque. [22] According to one of the aspects of the invention, the data processing device is arranged to run a diagnostic algorithm based on a fusion of vital data, in particular a respiratory rate, an amplitude of respiration, a time of inspiration and expiration, heart rhythm and arrhythmia.
[23] Selon l’un des aspects de l’invention, l’algorithme utilise des tempĂ©ratures mesurĂ©es sur des zones remarquables, localisĂ©es par traitement de l'image, ou encore le taux d’oxygĂšne liĂ© Ă  la personne examinĂ©e. [23] According to one of the aspects of the invention, the algorithm uses temperatures measured on remarkable areas, located by image processing, or even the oxygen level linked to the person examined.
[24] De prĂ©fĂ©rence, ces zones remarquables de mesure de tempĂ©rature sont localisĂ©es Ă  l’intĂ©rieur de la bouche, sur le bout du nez, sur les pommettes et la paume de la main. [24] Preferably, these remarkable temperature measurement zones are located inside the mouth, on the tip of the nose, on the cheekbones and the palm of the hand.
[25] Selon l’un des aspects de l’invention, l’algorithme de diagnostic utilise une caractĂ©risation de la personne, telles que des donnĂ©es d’ñge, de genre, d’habillage, de taille, d’indice de masse corporelle, encore appelĂ© BMI. [25] According to one of the aspects of the invention, the diagnostic algorithm uses a characterization of the person, such as data on age, gender, clothing, height, body mass index , also called BMI.
[26] Selon l’un des aspects de l’invention, le systĂšme est agencĂ© pour rĂ©aliser l’acquisition de donnĂ©es d’examen jusqu’à la mise Ă  disposition de l’information de diagnostic dans un laps de temps compris notamment entre 30 et 120 secondes. [27] Selon l’un des aspects de l’invention, le systĂšme est agencĂ© pour permettre une acquisition des donnĂ©es d’examen en faisant des mesures Ă  une distance de 60 cm Ă  2 m entre le dispositif d’acquisition et la personne. On Ă©vite que la personne n’ait Ă  ĂȘtre en contact avec le dispositif d’acquisition. [26] According to one of the aspects of the invention, the system is arranged to carry out the acquisition of examination data until the provision of the diagnostic information in a period of time comprised in particular between 30 and 120 seconds. [27] According to one of the aspects of the invention, the system is arranged to allow acquisition of examination data by taking measurements at a distance of 60 cm to 2 m between the acquisition device and the person. It is avoided that the person has to be in contact with the acquisition device.
[28] L’invention permet ainsi un diagnostic rapide sans dĂ©lai d’acheminement additionnel vers un mĂ©decin par exemple. Les informations de diagnostic peuvent, le cas Ă©chĂ©ant, ĂȘtre envoyĂ©s automatiquement Ă  un mĂ©decin et peuvent ĂȘtre conservĂ©s sur un systĂšme de stockage de donnĂ©es de type Cloud. [28] The invention thus allows rapid diagnosis without additional delay in getting to a doctor, for example. Diagnostic information can, if necessary, be automatically sent to a doctor and can be kept on a cloud-type data storage system.
[29] Selon l’un des aspects de l’invention, le dispositif de traitement de donnĂ©es utilise un algorithme d’analyse des donnĂ©es d’examen acquises et, le cas Ă©chĂ©ant, de tri des personnes dans le but de dĂ©tecter les cas de personnes malades, en se basant sur l'ensemble des donnĂ©es collectĂ©es et une intelligence artificielle dont le premier niveau d'apprentissage est rĂ©alisĂ© sur un Ă©chantillon en milieu hospitalier. [29] According to one of the aspects of the invention, the data processing device uses an algorithm for analyzing the acquired examination data and, if necessary, for sorting people with the aim of detecting cases of sick people, based on all the data collected and an artificial intelligence whose first level of learning is carried out on a sample in a hospital environment.
[30] Cet apprentissage par l’intelligence artificielle peut ĂȘtre rĂ©alisĂ©e au moyen d'un set de mesures collectĂ© par le systĂšme mais aussi au moyen du suivi mĂ©dical des patients. Ceci permet l'amĂ©lioration du modĂšle au cours du temps. [30] This learning by artificial intelligence can be carried out by means of a set of measurements collected by the system but also by means of the medical follow-up of patients. This allows the improvement of the model over time.
[31] Selon l’un des aspects de l’invention, les mesures rĂ©alisĂ©es par le dispositif d’acquisition peuvent servir pour affiner ultĂ©rieurement le diagnostic fait par l’intelligence artificielle. [31] According to one of the aspects of the invention, the measurements taken by the acquisition device can be used to subsequently refine the diagnosis made by the artificial intelligence.
[32] GrĂące Ă  l’invention, la pose d’un diagnostic peut se faire sans contact avec la personne, ce qui limite les risques de contamination, ce qui est particuliĂšrement avantageux par exemple dans le cas d’une pandĂ©mie telle que celle liĂ©e au COVID 19. [32] Thanks to the invention, a diagnosis can be made without contact with the person, which limits the risks of contamination, which is particularly advantageous, for example, in the case of a pandemic such as that linked to COVID 19.
[33] Selon l’un des aspects de l’invention, les donnĂ©es d’examen mesurĂ©es comprennent au moins l’une des donnĂ©es suivantes : des tempĂ©ratures mesurĂ©es en diffĂ©rents points du corps de la personne Ă  examiner, une caractĂ©ristique respiratoire ou cardiaque. [33] According to one of the aspects of the invention, the measured examination data includes at least one of the following data: temperatures measured at different points of the body of the person to be examined, a respiratory or cardiac characteristic.
[34] Selon l’un des aspects de l’invention, le dispositif d’acquisition est agencĂ© pour acquĂ©rir des donnĂ©es d’examen comprenant une tempĂ©rature extĂ©rieure, une tempĂ©rature mesurĂ©e sur une pommette de la personne, une tempĂ©rature mesurĂ©e sur le bout du nez de la personne, et Ă©galement le cas Ă©chĂ©ant, une tempĂ©rature maximale du visage et une tempĂ©rature d’un vĂȘtement ou d’une surface Ă  tempĂ©rature contrĂŽlĂ©e de rĂ©fĂ©rence. [34] According to one of the aspects of the invention, the acquisition device is arranged to acquire examination data comprising an outside temperature, a temperature measured on a cheekbone of the person, a temperature measured on the tip of the person's nose, and also, where appropriate, a maximum face temperature and a reference temperature-controlled garment or surface temperature.
[35] Selon l’un des aspects de l’invention, les points remarquables de mesure sont localisĂ©s par une intelligence artificielle au moyen d’un organigramme d’identification d’objet. [35] According to one of the aspects of the invention, the remarkable measurement points are located by an artificial intelligence by means of an object identification flowchart.
[36] Selon l’un des aspects de l’invention, la tempĂ©rature relative Ă  un point remarquable est obtenue par moyenne temporelle et par moyenne des tempĂ©ratures d’une surface dĂ©finie par des pixels issu d’une image de camĂ©ra infrarouge Ă  proximitĂ© du point remarquable identifiĂ© sur l’image visible au moyen d’un algorithme d’identification d’objets. [36] According to one of the aspects of the invention, the temperature relative to a remarkable point is obtained by time average and by average of the temperatures of a surface defined by pixels taken from an infrared camera image near the remarkable point identified on the visible image by means of an object identification algorithm.
[37] Selon l’un des aspects de l’invention, l’identification des caractĂ©risations personnelles se fait au moyen des camĂ©ras Rouge Vert Bleu (ou camĂ©ra RGB) ou Infrarouge lointain (camĂ©ra FIR) en complĂ©ment d’une lecture d’identitĂ© de la personne, grĂące Ă  un systĂšme de classification dont l’apprentissage peut ĂȘtre rĂ©alisĂ© sur des images RGB (Rouge Vert Bleu) ou Infrarouge. L’utilisation d’un plus grand nombre de paramĂštres, notamment l’ñge, le genre, la taille, l’indice de masse corporelle, le phĂ©notype par exemple, sert Ă  amĂ©liorer les modĂšles de diagnostic. [37] According to one of the aspects of the invention, the identification of personal characterizations is done by means of Red Green Blue cameras (or RGB camera) or Far Infrared (FIR camera) in addition to an identity reading of the person, thanks to a classification system which can be learned on RGB (Red Green Blue) or Infrared images. The use of more parameters, including age, gender, height, body mass index, phenotype for example, serves to improve diagnostic models.
[38] Selon l’un des aspects de l’invention, le modĂšle de diagnostic, ou algorithme de diagnostic, qui est nourri de plus de donnĂ©es telles que des tempĂ©ratures remarquables du corps, une tempĂ©rature ambiante, une classe de caractĂ©ristiques personnelles, une heure du jour, peut ĂȘtre agencĂ© pour en plus utiliser des donnĂ©es de parcours de la personne examinĂ©e pour vĂ©rifier si elle a croisĂ© une personne malade ou est passĂ©e par une rĂ©gion Ă  risque. [38] According to one of the aspects of the invention, the diagnostic model, or diagnostic algorithm, which is fed with more data such as remarkable body temperatures, ambient temperature, a class of personal characteristics, a time of day, can be arranged to additionally use route data of the examined person to check whether he has come across a sick person or has passed through a region at risk.
[39] Selon l’un des aspects de l’invention, le systĂšme est agencĂ© pour fonctionner en l’absence d’un radar et en utilisant les camĂ©ras RGB pour estimer les paramĂštres cardiaques et respiratoires. [39] According to one of the aspects of the invention, the system is arranged to operate in the absence of a radar and using RGB cameras to estimate cardiac and respiratory parameters.
[40] Selon l’un des aspects de l’invention, la tempĂ©rature relative Ă  un point remarquable peut ĂȘtre obtenue par moyenne temporelle et par moyenne des tempĂ©ratures d’une surface dĂ©finie par des pixels issu d’une image de camĂ©ra Ă  proximitĂ© du point remarquable. Le point remarquable est par exemple dĂ©fini gĂ©omĂ©triquement au moyen d’une zone d’image appelĂ©e Building box, qui l’entoure, par exemple au moyen de la moyenne gĂ©omĂ©trique des cĂŽtĂ©s de la zone de l’image. Cette zone d’image est une surface dĂ©limitĂ©e par une sĂ©rie de points qui est construite par un algorithme d’identification d’objets. [40] According to one of the aspects of the invention, the temperature relative to a remarkable point can be obtained by time average and by average of the temperatures of a surface defined by pixels taken from a camera image near the remarkable point. The remarkable point is for example defined geometrically by means of an image zone called Building box, which surrounds it, for example by means of the geometric mean of the sides of the image area. This image area is a surface delimited by a series of points which is constructed by an object identification algorithm.
[41 ] Selon l’un des aspects de l’invention, le systĂšme est dĂ©pourvu de camĂ©ra RGB et/ou n’utilise pas la surface dont la tempĂ©rature est contrĂŽlĂ©e. Dans ce cas, le systĂšme utilise la tempĂ©rature externe et un modĂšle de transfert thermique sur les zones habillĂ©es ou encore uniquement les Ă©carts de tempĂ©ratures entre les points remarquables. [41] According to one of the aspects of the invention, the system does not have an RGB camera and/or does not use the surface whose temperature is controlled. In this case, the system uses the external temperature and a heat transfer model on the covered areas or even only the temperature differences between the remarkable points.
[42] Selon l’un des aspects de l’invention, le systĂšme est agencĂ© pour utiliser une fusion de mesures sans contact, notamment de signaux vitaux et d'imagerie thermique et visible. [42] According to one of the aspects of the invention, the system is arranged to use a fusion of non-contact measurements, in particular of vital signals and thermal and visible imaging.
[43] L’information de diagnostic est comporte une classe choisie parmi trois classes prĂ©dĂ©terminĂ©es qui sont « Personne saine », « Personne avec une suspicion de maladie », « Personne avec une forte probabilitĂ© de maladie ». [43] The diagnostic information is comprised of a class chosen from among three predetermined classes which are "Healthy person", "Person with a suspicion of disease", "Person with a high probability of disease".
[44] L’information de diagnostic peut Ă©galement comporter une Ă©valuation de la gravitĂ© de la maladie. [44] Diagnostic information may also include an assessment of disease severity.
[45] L’invention a Ă©galement pour objet un procĂ©dĂ© pour fournir une information de diagnostic pour la dĂ©tection d’une maladie sur une personne, notamment une maladie contagieuse telle que le COVID 19, ce procĂ©dĂ© comportant les Ă©tapes suivantes: [45] The invention also relates to a method for providing diagnostic information for the detection of a disease in a person, in particular a contagious disease such as COVID 19, this method comprising the following steps:

[105] Ces capteurs et camĂ©ras, qui font partie du dispositif d’acquisition 7, sont reprĂ©sentĂ©s par la rĂ©fĂ©rence 2 sur la figure 1. Certains capteurs 2 sont par exemple disposĂ©s sur un plafond du vĂ©hicule. L’une des autres camĂ©ras 2 est disposĂ©e dans un montant latĂ©ral 6 du vĂ©hicule V. [105] These sensors and cameras, which are part of the acquisition device 7, are represented by the reference 2 in Figure 1. Some sensors 2 are for example arranged on a ceiling of the vehicle. One of the other cameras 2 is arranged in a side upright 6 of the vehicle V.
[106] Le capteur rythme cardiaque et respiration peut ĂȘtre dans le dossier du siĂšge ou dans la console centrale au niveau de la cuisse du passager, ceci Ă©tant no limitatif. [106] The heart rate and respiration sensor may be in the seat back or in the center console at the level of the passenger's thigh, this being non-limiting.
[107] Ces capteurs 2 sont reliĂ©s pour Ă©changes d’informations avec un dispositif de traitement de donnĂ©es 3 placĂ©e sur le vĂ©hicule V. [107] These sensors 2 are connected for exchange of information with a data processing device 3 placed on the vehicle V.
[108] Le dispositif de traitement de donnĂ©es 3 comporte une unitĂ© d’intelligence artificielle agencĂ©e pour traiter les donnĂ©es d’examen obtenues par le dispositif d’acquisition 7 et fournir ladite information de diagnostic. [109] Le dispositif de traitement de donnĂ©es 3 et le dispositif d’affichage 30 font partie d’un mĂȘme appareil, par exemple un ordinateur, notamment un ordinateur portable. [108] The data processing device 3 comprises an artificial intelligence unit arranged to process the examination data obtained by the acquisition device 7 and supply said diagnostic information. [109] The data processing device 3 and the display device 30 are part of the same device, for example a computer, in particular a laptop computer.
[110] Dans ce cas, le dispositif d’affichage 30 est un Ă©cran de l’ordinateur portable et le dispositif de traitement de donnĂ©es comprend microprocesseur de cet ordinateur. [110] In this case, the display device 30 is a screen of the laptop computer and the data processing device includes this computer's microprocessor.
[111] Le dispositif d’affichage 30 est agencĂ© pour ĂȘtre visible de la personne examinĂ©e, et notamment le dispositif d’affichage, qui comprend notamment un Ă©cran, est distant du dispositif de traitement de donnĂ©es, ces dispositif d’affichage et de traitement de donnĂ©es Ă©tant par exemple reliĂ©s entre eux par une liaison sans fil, par exemple par un protocole de communication 3G, 4G ou 5G, ou par le rĂ©seau Internet, ou Wifi par exemple. [111] The display device 30 is arranged to be visible to the person examined, and in particular the display device, which notably comprises a screen, is remote from the data processing device, these display and processing devices data being for example interconnected by a wireless link, for example by a 3G, 4G or 5G communication protocol, or by the Internet network, or Wifi for example.
[112] Le dispositif d’affichage 30, et Ă©galement le dispositif de traitement de donnĂ©es 3, sont ici agencĂ©es pour ĂȘtre embarquĂ©s sur un vĂ©hicule automobile. [112] The display device 30, and also the data processing device 3, are here arranged to be embedded in a motor vehicle.
[113] En variante, le dispositif d’affichage 30, et Ă©ventuellement Ă©galement le dispositif de traitement de donnĂ©es 3, sont agencĂ©s pour ĂȘtre placĂ©s de maniĂšre fixe, dans un bĂątiment ou une cour extĂ©rieure par exemple. [113] As a variant, the display device 30, and possibly also the data processing device 3, are arranged to be placed in a fixed manner, in a building or an outdoor courtyard for example.
[114] Le dispositif de traitement 3 est agencé pour faire le diagnostic de maniÚre automatique, sans une intervention humaine. [114] The processing device 3 is arranged to make the diagnosis automatically, without human intervention.
[115] Le dispositif d’acquisition 7 de donnĂ©es d’examen est agencĂ© pour permettre des mesures sans contact et Ă  distance de sĂ©curitĂ©, de signaux vitaux et d'imagerie thermique et visible sur la personne Ă  examiner. [115] The examination data acquisition device 7 is arranged to allow non-contact and safety distance measurements of vital signals and thermal and visible imaging on the person to be examined.
[116] Le systĂšme selon l’invention utilise ainsi avantageusement la fusion de mesures sans contact et Ă  distance de sĂ©curitĂ©, de signaux vitaux et d'imagerie thermique et visible. [116] The system according to the invention thus advantageously uses the fusion of measurements without contact and at a safe distance, vital signals and thermal and visible imaging.
[117] L’unitĂ© d’intelligence artificielle est agencĂ©e pour utiliser un modĂšle de diagnostic basĂ© sur l'intelligence artificielle et nourri par un nombre raisonnable de mesures cliniques. [117] The artificial intelligence unit is arranged to use a diagnostic model based on artificial intelligence and fed by a reasonable number of clinical measures.
[118] L’invention permet de rĂ©alisation des diagnostics de maniĂšre mobile. Sa mise en place, par exemple Ă  l’aide d’une camĂ©ra thermique, un capteur de mesure physiologique tel qu’un radar et un ordinateur personnel portable, est facile. [118] The invention allows diagnostics to be carried out in a mobile manner. Its implementation, for example using a thermal camera, a sensor of physiological measurement such as a radar and a portable personal computer, is easy.
[119] Le dispositif d’acquisition 7 comprend un radar pour acquĂ©rir des donnĂ©es relatives aux signes vitaux de la personne, une camĂ©ra thermique pour les mesures de tempĂ©rature fournissant des donnĂ©es de tempĂ©rature, et une camĂ©ra fonctionnant dans le spectre visible pour la caractĂ©risation de la personne testĂ©e fournissant des donnĂ©es caractĂ©risation de la personne. [119] The acquisition device 7 comprises a radar to acquire data relating to the vital signs of the person, a thermal camera for temperature measurements providing temperature data, and a camera operating in the visible spectrum for the characterization of the person being tested providing data characterizing the person.
[120] Le dispositif de traitement de données 3 est agencé pour faire tourner un algorithme de diagnostic basé sur une fusion des données vitales, notamment un rythme respiratoire, une amplitude de respiration, un temps d'inspiration et d'expiration, un rythme et arythmie cardiaque, une oxymétrie. [120] The data processing device 3 is arranged to run a diagnostic algorithm based on a fusion of vital data, in particular a breathing rhythm, a breathing amplitude, an inspiration and expiration time, a rhythm and cardiac arrhythmia, oximetry.
[121] L’algorithme utilise des tempĂ©ratures mesurĂ©es sur des zones remarquables, localisĂ©es par traitement de l'image. [121] The algorithm uses temperatures measured on remarkable areas, localized by image processing.
[122] De prĂ©fĂ©rence, ces zones remarquables de mesure de tempĂ©rature sont localisĂ©es Ă  l’intĂ©rieur de la bouche, sur le bout du nez, sur les pommettes et la paume de la main. [122] Preferably, these remarkable temperature measurement zones are located inside the mouth, on the tip of the nose, on the cheekbones and the palm of the hand.
[123] L’algorithme de diagnostic utilise une caractĂ©risation de la personne, telles que des donnĂ©es d’ñge, de genre, d’habillage, de taille, d’indice de masse corporelle. [123] The diagnostic algorithm uses a characterization of the person, such as data on age, gender, dress, height, body mass index.
[124] Le systĂšme est agencĂ© pour rĂ©aliser l’acquisition de donnĂ©es d’examen jusqu’à la mise Ă  disposition de l’information de diagnostic dans un laps de temps compris notamment entre 30 et 120 secondes. [124] The system is designed to carry out the acquisition of examination data until the provision of diagnostic information in a period of time comprised in particular between 30 and 120 seconds.
[125] L’invention permet ainsi un diagnostic rapide sans dĂ©lai d’acheminement additionnel vers un mĂ©decin par exemple. Les informations de diagnostic peuvent, le cas Ă©chĂ©ant, ĂȘtre envoyĂ©s automatiquement Ă  un mĂ©decin et peuvent ĂȘtre conservĂ©s sur un systĂšme de stockage de donnĂ©es 40 de type Cloud. [125] The invention thus allows rapid diagnosis without additional delay in getting to a doctor, for example. The diagnostic information can, if necessary, be sent automatically to a doctor and can be kept on a data storage system 40 of Cloud type.
[126] Le dispositif de traitement de donnĂ©es 3 utilise un algorithme d’analyse des donnĂ©es d’examen acquises et, le cas Ă©chĂ©ant, de tri des personnes dans le but de dĂ©tecter les cas de personnes malades, en se basant sur l'ensemble des donnĂ©es collectĂ©es et une intelligence artificielle dont le premier niveau d'apprentissage est rĂ©alisĂ© sur un Ă©chantillon en milieu hospitalier. [127] Les mesures rĂ©alisĂ©es par le dispositif d’acquisition peuvent servir pour affiner ultĂ©rieurement le diagnostic fait par l’intelligence artificielle. [126] The data processing device 3 uses an algorithm for analyzing the acquired examination data and, if necessary, sorting people with the aim of detecting cases of sick people, based on the set collected data and an artificial intelligence whose first level of learning is carried out on a sample in a hospital environment. [127] The measurements taken by the acquisition device can be used to later refine the diagnosis made by the artificial intelligence.
[128] GrĂące Ă  l’invention, la pose d’un diagnostic peut se faire sans contact avec la personne, ce qui limite les risques de contamination, ce qui est particuliĂšrement avantageux par exemple dans le cas d’une pandĂ©mie telle que celle liĂ©e au COVID 19. [128] Thanks to the invention, a diagnosis can be made without contact with the person, which limits the risks of contamination, which is particularly advantageous, for example, in the case of a pandemic such as that linked to COVID 19.
[129] Selon l’un des aspects de l’invention, les donnĂ©es d’examen mesurĂ©es comprennent au moins l’une des donnĂ©es suivantes : des tempĂ©ratures mesurĂ©es en diffĂ©rents points du corps de la personne Ă  examiner, une caractĂ©ristique respiratoire ou cardiaque. [129] According to one of the aspects of the invention, the measured examination data includes at least one of the following data: temperatures measured at different points of the body of the person to be examined, a respiratory or cardiac characteristic.
[130] Le dispositif d’acquisition 7 est agencĂ© pour acquĂ©rir des donnĂ©es d’examen comprenant une tempĂ©rature extĂ©rieure, une tempĂ©rature mesurĂ©e sur une pommette de la personne, une tempĂ©rature mesurĂ©e sur le bout du nez de la personne, et Ă©galement le cas Ă©chĂ©ant, une tempĂ©rature maximale du visage et une tempĂ©rature d’un vĂȘtement ou d’une surface Ă  tempĂ©rature contrĂŽlĂ©e de rĂ©fĂ©rence. [130] The acquisition device 7 is arranged to acquire examination data comprising an outside temperature, a temperature measured on a cheekbone of the person, a temperature measured on the tip of the person's nose, and also, if necessary , a peak face temperature, and a reference temperature-controlled clothing or surface temperature.
[131] Les points remarquables de mesure sont localisĂ©s par une intelligence artificielle au moyen d’un organigramme d’identification d’objet. [131] The remarkable points of measurement are located by an artificial intelligence by means of an object identification flowchart.
[132] L’identification des caractĂ©risations personnelles se fait au moyen des camĂ©ras Rouge Vert Bleu (ou camĂ©ra RGB) ou Infrarouge lointain (camĂ©ra FIR) en complĂ©ment d’une lecture d’identitĂ© de la personne, grĂące Ă  un systĂšme de classification dont l’apprentissage peut ĂȘtre rĂ©alisĂ© sur des images RGB (Rouge Vert Bleu) ou Infrarouge. L’utilisation d’un plus grand nombre de paramĂštres, notamment l’ñge, le genre, la taille, l’indice de masse corporelle, le phĂ©notype par exemple, sert Ă  amĂ©liorer les modĂšles de diagnostic. [132] The identification of personal characterizations is done by means of Red Green Blue cameras (or RGB camera) or Far Infrared (FIR camera) in addition to a reading of the person's identity, thanks to a classification system whose learning can be performed on RGB (Red Green Blue) or Infrared images. The use of more parameters, including age, gender, height, body mass index, phenotype for example, serves to improve diagnostic models.
[133] Le modĂšle de diagnostic, ou algorithme de diagnostic, qui est nourri de plus de donnĂ©es telles que des tempĂ©ratures remarquables du corps, une tempĂ©rature ambiante, une classe de caractĂ©ristiques personnelles, une heure du jour, peut ĂȘtre agencĂ© pour en plus utiliser des donnĂ©es de parcours de la personne examinĂ©e pour vĂ©rifier si elle a croisĂ© une personne malade ou est passĂ©e par une rĂ©gion Ă  risque. [134] La tempĂ©rature relative Ă  un point remarquable peut ĂȘtre obtenue par moyenne temporelle et par moyenne des tempĂ©ratures d’une surface dĂ©finie par des pixels issu d’une image de camĂ©ra Ă  proximitĂ© du point remarquable. Le point remarquable est par exemple dĂ©fini gĂ©omĂ©triquement au moyen d’une zone d’image appelĂ©e Building box, qui l’entoure. Cette zone d’image est une surface dĂ©limitĂ©e par une sĂ©rie de points qui est construite par un algorithme d’identification d’objets. [133] The diagnostic model, or diagnostic algorithm, which is fed with more data such as remarkable body temperatures, ambient temperature, class of personal characteristics, time of day, can be arranged to additionally use journey data of the person examined to check whether they have crossed paths with a sick person or passed through a region at risk. [134] The temperature relative to a remarkable point can be obtained by temporal average and by average of the temperatures of a surface defined by pixels resulting from a camera image near the remarkable point. The remarkable point is for example defined geometrically by means of an image zone called Building box, which surrounds it. This image area is a surface delimited by a series of points which is constructed by an object identification algorithm.
[135] L’information de diagnostic est comporte une classe choisie parmi trois classes prĂ©dĂ©terminĂ©es qui sont « Personne saine », « Personne avec une suspicion de maladie », « Personne avec une forte probabilitĂ© de maladie ». [135] The diagnostic information is comprised of a class chosen from three predetermined classes which are "Healthy person", "Person with a suspicion of disease", "Person with a high probability of disease".
[136] L’invention met ainsi en oeuvre les Ă©tapes suivantes: [136] The invention thus implements the following steps:
- acquĂ©rir des donnĂ©es d’examen sur la personne Ă  l’aide du dispositif d’acquisition 7, qui sont les Ă©tapes 20 Ă  25 de la figure 2, - acquiring examination data on the person using the acquisition device 7, which are steps 20 to 25 in Figure 2,

[137] Les Ă©tapes 20 Ă  25 sont les suivantes : [137] Steps 20 to 25 are as follows:
- l’identification des caractĂ©risations personnelles se fait au moyen des camĂ©ras Rouge Vert Bleu (ou camĂ©ra RGB), c’est l’étape 20, - the identification of personal characterizations is done by means of Red Green Blue cameras (or RGB camera), this is step 20,

[141 ] De mĂȘme les informations utiles au modĂšle de diagnostic, ou algorithme de diagnostic, peuvent ĂȘtre reçues du systĂšme distant de type Cloud. [141] Similarly, information useful for the diagnostic model, or diagnostic algorithm, can be received from the cloud-type remote system.
[142] Potentiellement deux caméras, NIR et FIR, sont utilisées. La caméra FIR pour les températures et les caractéristiques de la respiration et la caméra NIR pour l'oxymétrie et le rythme cardiaque. [142] Potentially two cameras, NIR and FIR, are used. The FIR camera for temperatures and respiration characteristics and the NIR camera for oximetry and heart rate.

[152] Les questions à poser sont à caractÚre médical, utiles pour améliorer le diagnostic en combinaison avec les autres données. [152] The questions to be asked are of a medical nature, useful to improve the diagnosis in combination with the other data.
[153] Le systĂšme 1 est agencĂ© pour effectuer, Ă  l’aide de l’un des capteurs 2 sans contact, une mesure dont les donnĂ©es de rĂ©sultat sont comparĂ©es Ă  une rĂ©ponse fournie par la personne en rĂ©ponse Ă  une question du questionnaire. [153] The system 1 is arranged to perform, using one of the contactless sensors 2, a measurement whose result data is compared with an answer provided by the person in response to a question in the questionnaire.
[154] On va maintenant dĂ©crire en rĂ©fĂ©rence Ă  la figure 3 diffĂ©rentes Ă©tapes de mise en oeuvre de l’invention. [154] We will now describe with reference to Figure 3 various stages of implementation of the invention.

[158] This step 51 can be performed by the person via a touch screen 35 coupled to a disinfection device 36 using UV. A microphone 33 can be used to record the person's responses to questions. A voice recognition device 38 is muted at the microphone 33 to input data picked up by the microphone 33 into the data processing unit 3.
[159] Des donnĂ©es de contexte 37, par exemple une tempĂ©rature ambiante, peut ĂȘtre acquise par un capteur 2. [159] Context data 37, for example an ambient temperature, can be acquired by a sensor 2.
[160] A l’étape 52, des caractĂ©ristiques liĂ©es Ă  la personne sont dĂ©terminĂ©es grĂące Ă  un ou plusieurs capteurs 2 via un systĂšme 39 de reconnaissance d’images objet, comme dĂ©crit dans l’exemple prĂ©cĂ©dent. [160] In step 52, characteristics related to the person are determined using one or more sensors 2 via an object image recognition system 39, as described in the previous example.
[161] Des questions supplĂ©mentaires sont posĂ©es Ă  l’issue de l’étape 52 pour prĂ©ciser l’état clinique de la personne. [162] Pour cette Ă©tape 53 de questions / rĂ©ponses, les questions sont choisies par exemple dans la liste suivante : Avez-vous mal Ă  la poitrine? Avez-vous une toux sĂšche? Avez-vous mal Ă  la gorge? Avez-vous le nez qui coule? Avez-vous du mal Ă  respirer ? [161] Additional questions are asked at the end of step 52 to clarify the person's clinical condition. [162] For this step 53 of questions/answers, the questions are chosen for example from the following list: Do you have chest pain? Do you have a dry cough? Do you have a sore throat? Do you have a runny nose? Do you have trouble breathing?
[163] Les rĂ©ponses peuvent ĂȘtre apportĂ©es par la personne via le microphone 33. [163] Answers can be given by the person via the microphone 33.
[164] A l’étape 54 suivante, les capteurs 2 procĂšdent Ă  l’acquisition de donnĂ©es relatives aux signes vitaux de la personne, comme dĂ©crit dans l‘exemple prĂ©cĂšdent. [164] In the following step 54, the sensors 2 proceed to the acquisition of data relating to the vital signs of the person, as described in the preceding example.
[165] Puis Ă  l’étape 55, l’intelligence artifice fournit un score prĂ©alable reprĂ©sentatif du diagnostic obtenu sur la base des donnĂ©es jusqu’alors saisies. [165] Then in step 55, the artificial intelligence provides a preliminary score representative of the diagnosis obtained on the basis of the data entered until then.
[166] A l’étape 56, des questions additionnelles sont posĂ©es Ă  la personne, et les rĂ©ponses obtenues sont utilisĂ©es pour affiner le score prĂ©alable obtenu Ă  l’étape 55. [166] In step 56, additional questions are asked of the person, and the answers obtained are used to refine the preliminary score obtained in step 55.
[167] Un score final est donnĂ© Ă  l’étape 57 par l’intelligence artificielle, qui est enregistrĂ© sur l’espace de stockage de donnĂ©es 40. [167] A final score is given in step 57 by the artificial intelligence, which is recorded on the data storage space 40.
[168] A l’étape 58, le score final est affichĂ© pour information Ă  la personne. [168] At step 58, the final score is displayed for information to the person.
[169] On va maintenant prĂ©senter un autre mode de rĂ©alisation de l’invention en rĂ©fĂ©rence Ă  la figure 4. [169] We will now present another embodiment of the invention with reference to Figure 4.
[170] Dans cet exemple, le systĂšme 1 d’aide pour fournir une information de diagnostic, lĂ©gĂšrement diffĂšrent de celui dĂ©crit plus haut, comporte: [170] In this example, the aid system 1 for providing diagnostic information, slightly different from that described above, comprises:
- un dispositif d’acquisition 7 de donnĂ©es d’examen sur la personne, ce dispositif d’acquisition comportant au moins un premier capteur, ici un capteur de mesure physiologique qui est un radar pour acquĂ©rir ces donnĂ©es d’examen, - a device 7 for acquiring examination data on the person, this acquisition device comprising at least a first sensor, here a physiological measurement sensor which is a radar for acquiring this examination data,
- un dispositif de traitement de donnĂ©es 3 agencĂ© pour recevoir ces donnĂ©es obtenues par le dispositif d’acquisition, - a data processing device 3 arranged to receive these data obtained by the acquisition device,
- un dispositif d’affichage 30 agencĂ© pour afficher une information de diagnostic de la maladie basĂ©e sur une analyse desdites donnĂ©es par le dispositif de traitement de donnĂ©es, cette information de diagnostic pouvant notamment ĂȘtre reprĂ©sentative d’un niveau de probabilitĂ© que la personne soit atteinte de la maladie, ce niveau de probabilitĂ© pouvant notamment ĂȘtre un score - a display device 30 arranged to display diagnostic information of the disease based on an analysis of said data by the data processing device, this diagnostic information being able in particular be representative of a level of probability that the person is affected by the disease, this level of probability possibly being in particular a score
- le dispositif d’acquisition 7 comprenant en outre un capteur de correction 33 diffĂ©rent dudit premier capteur, Ă  savoir le radar, et agencĂ© pour acquĂ©rir au moins une donnĂ©e sur la personne, cette donnĂ©e Ă©tant une donnĂ©e de correction diffĂ©rente de donnĂ©es acquises par le premier capteur, - the acquisition device 7 further comprising a correction sensor 33 different from said first sensor, namely the radar, and arranged to acquire at least one datum on the person, this datum being a different correction datum from data acquired by the first sensor,
- le dispositif de traitement de donnĂ©es Ă©tant agencĂ© pour utiliser cette donnĂ©e de correction pour corriger les donnĂ©es d’examen fournies par le premier capteur. - the data processing device being arranged to use this correction data to correct the examination data provided by the first sensor.
[171] Ce capteur de correction 33 est agencĂ© pour acquĂ©rir une donnĂ©e reprĂ©sentative d’une voix de la personne. [171] This correction sensor 33 is arranged to acquire data representative of a person's voice.
[172] Ce capteur de correction 33 agencĂ© pour acquĂ©rir une donnĂ©e reprĂ©sentative d’une voix de la personne comporte un microphone 33, notamment un microphone directionnel ou une camĂ©ra. [172] This correction sensor 33 arranged to acquire data representative of a voice of the person comprises a microphone 33, in particular a directional microphone or a camera.
[173] On peut prĂ©voir que le dispositif d’acquisition 7 comporte Ă  la fois un capteur de correction agencĂ© pour acquĂ©rir une donnĂ©e reprĂ©sentative d’un mouvement de la personne et un capteur de correction agencĂ© pour acquĂ©rir une donnĂ©e reprĂ©sentative d’une voix de la personne. [173] Provision may be made for the acquisition device 7 to comprise both a correction sensor arranged to acquire data representative of a movement of the person and a correction sensor arranged to acquire data representative of a voice of the person.
[174] Ce capteur de correction pour acquĂ©rir une donnĂ©e reprĂ©sentative d’un mouvement de la personne comporte une camĂ©ra, notamment de type 3D, pour acquĂ©rir une donnĂ©e reprĂ©sentative d’un mouvement de la personne. [174] This correction sensor for acquiring data representative of a person's movement comprises a camera, in particular of the 3D type, for acquiring data representative of a person's movement.
[175] Cette caméra est notamment une caméra fonctionnant sur le principe du temps de vol (en anglais : Time of Flight, TOF) qui permet de mesurer en temps réel une scÚne en 3 dimensions (3D). Ce type de caméra est connu [175] This camera is in particular a camera operating on the principle of time of flight (in English: Time of Flight, TOF) which makes it possible to measure a scene in real time in 3 dimensions (3D). This type of camera is known
[176] Le radar est agencĂ© notamment pour acquĂ©rir une donnĂ©e reprĂ©sentative d’un rythme respiratoire de la personne, notamment en dĂ©tectant le mouvement de la peau de la personne. [176] The radar is arranged in particular to acquire data representative of the person's breathing rate, in particular by detecting the movement of the person's skin.
[177] Le radar est agencĂ© pour ĂȘtre placĂ© face Ă  la personne ou dans le dos de la personne. [177] The radar is arranged to be placed in front of the person or behind the person.
[178] Bien entendu, des capteurs autres que le radar peuvent ĂȘtre utilisĂ©s, par exemple une camĂ©ra Proche Infrarouge. [179] Le dispositif de traitement de donnĂ©es 3 est agencĂ© pour rĂ©aliser la correction des donnĂ©es d’examen en fonction de la donnĂ©e de correction Ă  l’aide d’une intelligence artificielle. [178] Of course, sensors other than radar can be used, for example a Near Infrared camera. [179] The data processing device 3 is arranged to carry out the correction of the examination data according to the correction data using an artificial intelligence.
[180] Le dispositif de traitement de données 3 est agencé pour obtenir un signal de correction basé sur les données de correction, ce signal de correction étant évolutif en fonction du temps. [180] The data processing device 3 is arranged to obtain a correction signal based on the correction data, this correction signal being evolving as a function of time.
[181] Le dispositif de traitement de donnĂ©es 3 est agencĂ© pour fournir les donnĂ©es d’examen, par exemple liĂ©es au rythme respiratoire, aprĂšs correction Ă  l’aide du signal de correction. [181] The data processing device 3 is arranged to provide the examination data, for example related to the breathing rate, after correction using the correction signal.
[182] L’invention permet de prendre en compte le bruit liĂ© aux mouvements de la personne et/ou Ă  sa voix, pour fournir des donnĂ©es d’examen fiables et prĂ©cises. [182] The invention makes it possible to take into account the noise linked to the movements of the person and/or to his voice, in order to provide reliable and precise examination data.
[183] En effet les mouvements et les paroles de la personne sont susceptibles de crĂ©er des interfĂ©rences dans l’acquisition de donnĂ©es, notamment de type physiologiques telles que le rythme respiratoire. [183] Indeed, the movements and words of the person are likely to create interference in the acquisition of data, in particular of physiological type such as the respiratory rate.
[184] On peut le voir par exemple sur les courbes de la figures 4. [184] This can be seen for example on the curves in figure 4.
[185] La courbe 101 illustre l’amplitude de l’erreur, au fil du temps, sur une mesure de rythme respiratoire sur la personne, cette erreur Ă©tant induite par des mouvements de la personne lors de la mesure et par le fait qu’elle parle pendant la mesure. [185] Curve 101 illustrates the magnitude of the error, over time, in a measurement of respiratory rate on the person, this error being induced by movements of the person during the measurement and by the fact that she speaks during the measurement.
[186] Cette amplitude d’erreur sur la courbe 101 est relativement grande. [186] This error amplitude on curve 101 is relatively large.
[187] La courbe 102 montre l’amplitude de l’erreur, au fil du temps, sur une mesure de rythme respiratoire sur la personne, lorsqu’est prise en compte une correction tenant compte des mouvements de la personne dĂ©tectĂ©s par la camĂ©ra de mouvements. [187] Curve 102 shows the magnitude of the error, over time, in a breathing rate measurement on the person, when taking into account a correction taking into account the movements of the person detected by the camera of movements.
[188] L’amplitude sur la courbe 102 est rĂ©duite par rapport Ă  la courbe 101. [188] The amplitude on curve 102 is reduced compared to curve 101.
[189] Enfin la courbe 103 illustre l’amplitude de l’erreur, au fil du temps, sur une mesure de rythme respiratoire sur la personne, lorsque sont prises en compte les corrections liĂ©es Ă  la fois aux mouvements et Ă  la parole de la personne. [189] Finally, curve 103 illustrates the amplitude of the error, over time, on a measurement of respiratory rate on the person, when the corrections linked to both the movements and the speech of the patient are taken into account. nobody.
[190] Cette courbe 103 est proche de zĂ©ro grĂące aux corrections rĂ©alisĂ©es. [191] Le systĂšme de l’invention permet ainsi de mettre en Ɠuvre le procĂ©dĂ© comportant les Ă©tapes suivantes: [190] This curve 103 is close to zero thanks to the corrections made. [191] The system of the invention thus makes it possible to implement the method comprising the following steps:
- acquĂ©rir des donnĂ©es d’examen sur la personne, Ă  l’aide d’un dispositif d’acquisition de donnĂ©es d’examen sur la personne, ce dispositif d’acquisition comportant au moins un premier capteur, notamment un capteur de mesure physiologique tel qu’un radar ou une camĂ©ra thermique pour acquĂ©rir ces donnĂ©es d’examen, notamment ce dispositif d’acquisition comportant une pluralitĂ© de capteurs agencĂ©s pour fonctionner sans contact avec la personne, notamment l’un au moins des capteurs sans contact Ă©tant agencĂ© pour acquĂ©rir une donnĂ©e rĂ©ponse fournie par la personne, - acquiring examination data on the person, using a device for acquiring examination data on the person, this acquisition device comprising at least a first sensor, in particular a sensor for physiological measurement such a radar or a thermal camera to acquire these examination data, in particular this acquisition device comprising a plurality of sensors arranged to operate without contact with the person, in particular at least one of the contactless sensors being arranged to acquire response data provided by the person,
- corriger ces donnĂ©es d’examen Ă  l’aide de donnĂ©es de correction, notamment acquises Ă  l’aide d’un capteur de correction. ) - correcting this examination data using correction data, in particular acquired using a correction sensor. )
