Description

dans un boîtier comportant une chape creuse constituée d'un fond et d'au moins un bras de cardan sur lequel s'appuie une coque creuse de forme de préférence sphérique. Le dispositif de prises de vues est placé dans la coque, les fils de connexion passant de la coque à l'intérieur de la chape par l'intermédiaire d'au moins une articulation assurant la mobilité de la coque autour d'un axe passant par son centre et perpendiculaire au bras de cardan et la chape étant elle-même mobile autour d'un axe perpendiculaire à l'axe précité et parallèle au bras de cardan. in a housing comprising a hollow yoke consisting of a bottom and at least one universal joint arm on which a hollow shell of preferably spherical shape is supported. The filming device is placed in the shell, the connection wires passing from the shell to the interior of the yoke via at least one hinge ensuring the mobility of the hull around an axis passing through its center and perpendicular to the universal joint arm and the yoke itself being movable about an axis perpendicular to the aforementioned axis and parallel to the universal joint arm.
Ce dispositif a pour inconvénient de ne pas proposer de solution pour la gestion de l'information concernant le positionnement réel de la caméra sur ses axes de rotation. En outre, l'utilisation des articulations comme moyen permettant de faire passer des câbles a pour désavantage de limiter les possibilités de rotation du module de prise de vues aux capacités de torsion desdits câbles. De plus, le boîtier de prise de vues ne possède pas de moyen de protection de l'objectif de la caméra qu'il contient. Ce document reste très vague quant aux capacités de zoom de la caméra. Or, le diamètre de la sphère de vision proposée par un tel dispositif, reste limité auxdites capacités de zoom. Le document français n° 2789253 décrit un dispositif de dôme pour caméra de vidéo surveillance remarquable en ce qu'il comporte un capot de protection nommé ogive qui n'est pas solidaire du fût, mais pivote avec la caméra dont la vision est assurée au travers d'une fenêtre optique à profil plat permettant une vision au-dessus de l'horizontale. L'étanchéité de la partie inférieure rotative est assurée à l'aide d'un joint à lèvre ou par une platine à bord rabattu qui trempe dans une gorge remplie de liquide. Bien que proposant une fenêtre de visualisation à profil plan autorisant une vision au-delà de l'horizontale et évitant une focalisation sur une surface sphérique ce dispositif nécessite un déplacement du dôme de protection en même temps que la caméra pour sa rotation selon un axe vertical. De plus, la surface sphérique est présente en extrémité d'ogive.This device has the disadvantage of not providing a solution for the management of information concerning the actual positioning of the camera on its axes of rotation. In addition, the use of the joints as a means for passing cables has the disadvantage of limiting the possibilities of rotation of the camera module torsion capabilities of said cables. In addition, the camera has no means of protecting the lens of the camera it contains. This document is very vague about the zoom capabilities of the camera. However, the diameter of the sphere of vision proposed by such a device remains limited to said zoom capabilities. The French document No. 2789253 describes a dome device for a video surveillance camera which is remarkable in that it includes a protective cap called a ogive which is not secured to the shaft, but pivots with the camera whose vision is ensured through a flat-profile optical window allowing vision above the horizontal. The sealing of the rotating lower part is ensured by means of a lip seal or by a flanged plate which dipped in a groove filled with liquid. Although offering a viewing window with a plane profile allowing a vision beyond the horizontal and avoiding focusing on a spherical surface this device requires a displacement of the protection dome at the same time as the camera for its rotation along a vertical axis. In addition, the spherical surface is present in ogive end.
Ce document reste vague sur les capacités de zoom de la caméra ainsi que sur les moyens de gestion de ses mouvements .This document remains vague on the zoom capabilities of the camera and on the means of management of its movements.
Un autre inconvénient constaté sur les dispositifs de l'art antérieur concerne la limitation du nombre et du type de moyens de prise de vues mis en œuvre. En effet, la plupart des dispositifs assure la gestion et la mise en mouvement d'un seul moyen de prise de vues de type vidéo classique. DESCRIPTION DE L'INVENTIONAnother disadvantage found on the devices of the prior art relates to the limitation of the number and type of shooting means implemented. Indeed, most of the devices provide management and movement of a single means of shooting conventional video type. DESCRIPTION OF THE INVENTION
Partant de cet état de fait, la demanderesse a mené des recherches ayant pour but de concevoir un dispositif mettant en œuvre un moyen de prise de vues ou une caméra, notamment à des fins de vidéo surveillance, obviant aux inconvénients de l'art antérieur.Based on this fact, the Applicant has conducted research aimed at designing a device implementing a means of shooting or a camera, especially for video surveillance purposes, overcoming the drawbacks of the prior art.
La demanderesse s'est attachée dans sa conception à essayer d'obtenir les différents avantages connus séparément dans les dispositifs de l'art antérieur.The Applicant has attached in its design to try to obtain the various advantages known separately in the devices of the prior art.
Ces recherches ont abouti à la conception d'un dispositif assurant la gestion et la mise en mouvement d'au moins un moyen de prise de vues, remarquable en ce qu'il est constitué par un boîtier qui, formant une enceinte de protection autour d'au moins un moyen de prise de vues, est monté mobile en rotation selon un premier axe par rapport à au moins un bras solidaire d'une platine qui est elle-même montée mobile en rotation selon un deuxième axe perpendiculaire au premier par rapport à un socle fixe, les deux mouvements de rotation étant réalisés sur trois cent soixante degrés sans butée, la disposition et les dimensions du moyen de prise de vues par rapport à la disposition et aux dimensions de la platine et du socle , - -This research led to the design of a device ensuring the management and the setting in motion of at least one means of shooting, remarkable in that it is constituted by a housing which, forming a protective enclosure around at least one camera means is rotatably mounted along a first axis with respect to at least one arm integral with a plate which is itself rotatably mounted along a second axis perpendicular to the first axis relative to a fixed base, the two rotational movements being carried out over three hundred and sixty degrees without stop, the arrangement and the dimensions of the means of shooting relative to the arrangement and the dimensions of the plate and the base, - -
définissant un champ de visibilité d'au moins deux cent soixante dix degrés.defining a field of view of at least two hundred and seventy degrees.
Ce boîtier de protection est donc susceptible de réaliser une rotation complète aussi bien selon un axe horizontal que selon un axe vertical. La caméra dispose d'une totale mobilité en rotation selon deux axes. Son champ visuel n'est limité que par la présence du socle dont le volume n'empêche pas l'objectif de la caméra d'aller au-delà de l'horizontale. En effet, ledit socle est avantageusement préformé pour de pas former un obstacle lorsque l'objectif de la caméra dépasse le plan horizontal. La mobilité permet de résoudre aussi bien les problèmes de vitesse de mise en mouvement que ceux de difficulté d'installation. Ainsi, il n'est plus nécessaire d'étudier très précisément en fonction notamment de toutes les pentes du terrain, le positionnement de la caméra. Le dispositif peut donc se disposer aussi bien debout que tête en bas. Ce dispositif est en outre sans dôme et n'est donc pas équipé d'un support de dôme qui limite le champ de vision du dispositif selon un angle de 180° au-dessus ou au dessous du support de dôme selon sa disposition.This protective case is thus capable of performing a complete rotation both along a horizontal axis and along a vertical axis. The camera has full mobility in rotation along two axes. Its visual field is limited only by the presence of the base whose volume does not prevent the camera's lens from going beyond the horizontal. Indeed, said base is advantageously preformed to not form an obstacle when the lens of the camera exceeds the horizontal plane. Mobility makes it possible to solve problems of speed of movement as well as problems of difficulty of installation. Thus, it is no longer necessary to study very precisely, in particular according to all the slopes of the terrain, the positioning of the camera. The device can be arranged as well as upside down. This device is also without a dome and is therefore not equipped with a dome holder which limits the field of view of the device at an angle of 180 ° above or below the dome support according to its arrangement.
Afin de permettre de proposer des fonctionnalités supplémentaires, le boîtier de protection du dispositif de l'invention accueille plusieurs moyens de prise de vues de même technologie. Cette caractéristique permet d'envisager des prises de vues périmétriques instantanées sans exiger un mouvement de rotation. De même, selon une autre caractéristique, le boîtier de protection accueille plusieurs moyens de prise de vues de technologies différentes comme par exemple des moyens de vision infrarouge ou ultraviolet proposant pour un seul dispositif plusieurs solutions de visibilité.In order to make it possible to propose additional functionalities, the protection case of the device of the invention accommodates several means of shooting of the same technology. This feature makes it possible to consider instantaneous perimeter shots without requiring a rotational movement. Similarly, according to another characteristic, the protection housing accommodates several different technologies shooting means such as infrared or ultraviolet viewing means proposing for a single device several visibility solutions.
Toujours dans le souci de proposer des fonctionnalités supplémentaires, la demanderesse a prévu certaines applications où le ou les moyens de prise de vues est associé dans le boîtier de protection à au moins un capteur proposant ainsi l'enregistrement de paramètres autres que visuels. Les applications d'un tel dispositif vont donc au-delà de la simple surveillance et comprennent notamment : la détection, suivi, le surveillance de processus, l'automatisation de surveillance, l'enregistrement de prise de vues, etc..Still with the aim of proposing additional functionalities, the Applicant has provided certain applications where the means of shooting is associated in the protective case with at least a sensor thus offering the recording of non-visual parameters. The applications of such a device therefore go beyond simple monitoring and include in particular: detection, monitoring, process monitoring, surveillance automation, recording of shots, etc.
Selon une autre caractéristique de l'invention, la disposition et les dimensions du moyen de prise de vues par rapport à la disposition et aux dimensions de la platine et du socle, définissent un champ de visibilité d'au moins deux cent soixante dix degrés.According to another characteristic of the invention, the arrangement and the dimensions of the means of shooting relative to the arrangement and the dimensions of the plate and the base, define a field of visibility of at least two hundred and seventy degrees.
Selon une caractéristique particulièrement avantageuse de l'invention, les mouvements de rotation sont assurés pour chaque axe par un moteur pas à pas et suivis pour chaque axe par un codeur. Ainsi, le dispositif fonctionne en boucle fermée c'est à dire qu'il dispose des éléments fonctionnels nécessaires pour reconnaitre les diverses positions angulaires prises par des sous-ensembles tournants. En outre, un tel suivi de position vient en parfaite adéquation avec une gestion beaucoup plus précise des mouvements que propose le dispositif de l'invention, précision de l'ordre du dixième de degré .According to a particularly advantageous characteristic of the invention, the rotational movements are ensured for each axis by a stepping motor and tracked for each axis by an encoder. Thus, the device operates in a closed loop that is to say that it has the necessary functional elements to recognize the various angular positions taken by rotating subassemblies. In addition, such a position tracking comes perfectly in line with a much more precise management of the movements proposed by the device of the invention, a precision of the order of a tenth of a degree.
Selon une autre caractéristique particulièrement avantageuse de l'invention, ledit boitier de protection comprend une fenêtre devant laquelle l'objectif du moyen de prise de vue est installé, fenêtre fermée par une plaque de matériau transparent. L'utilisation d'un élément plan pour la protection de l'objectif du moyen de prise de vue évite les inconvénients de l'art antérieur à savoir la focalisation sur les parties sphériques protectrices.According to another particularly advantageous feature of the invention, said protective housing comprises a window in front of which the lens of the shooting means is installed, window closed by a plate of transparent material. The use of a planar element for the protection of the objective of the shooting means avoids the drawbacks of the prior art namely focusing on the spherical protective parts.
Cette caractéristique permet d'envisager un moyen de prise de vues à capacités de zoom largement supérieures à ce qui est normalement proposé pour les dispositifs de type dôme. Ainsi, la capacité du zoom n'est limitée que — —This feature makes it possible to envisage a means of shooting with zooming capabilities much greater than what is normally proposed for dome-type devices. Thus, the zoom capability is limited only - -
par les limitations technologiques actuelles des dispositifs de prise de vues embarqués. Aussi, le dispositif de l'invention a été conçu pour recevoir les moyens de prises de vues les plus récents et dont les capacités aussi bien en zoom qu'en précision sont susceptibles d'augmenter. Ainsi, selon une autre caractéristique particulièrement avantageuse, la capacité du zoom du moyen de prise de vues est au moins si ce n'est largement supérieure à vingt-cinq. Selon une variante, ledit boîtier de protection comprend accueille plusieurs moyens de prises de vues et est ménagé de plusieurs fenêtres devant lesquelles l'objectif des moyens de prise de vues est installé, fenêtres fermées par une plaque de matériau adapté au type de moyen de prise de vues. En effet, selon le type de moyen de prise de vues (spectre visuel classique, infrarouge, ultraviolet, etc..) la fenêtre de protection ne peut être protégée par le même matériau.by the current technological limitations of on-board cameras. Also, the device of the invention has been designed to receive the most recent shooting means and whose capabilities in both zooming and precision are likely to increase. Thus, according to another particularly advantageous characteristic, the zoom capability of the imaging means is at least substantially greater than twenty-five. According to a variant, said protective housing comprises accommodates several means of shooting and is provided with several windows in front of which the lens of the camera means is installed, windows closed by a plate of material adapted to the type of gripping means of views. Indeed, depending on the type of shooting medium (conventional visual spectrum, infrared, ultraviolet, etc. ..) the protection window can not be protected by the same material.
Une autre caractéristique particulièrement avantageuse de l'invention concerne ses moyens de nettoyage. En effet, le dispositif de l'invention est remarquable en ce que ladite platine comprend au niveau de la base du bras, au moins un moyen de nettoyage. Ainsi, un procédé de travail du dispositif consiste à faire réaliser au boîtier de protection une rotation pour amener la fenêtre de visualisation au niveau du moyen de nettoyage pour réaliser le nettoyage de cette dernière. La zone vers laquelle le moyen de prise de vues est aveugle est donc avantageusement utilisée pour recevoir un moyen de nettoyage .Another particularly advantageous feature of the invention relates to its cleaning means. Indeed, the device of the invention is remarkable in that said plate comprises at the base of the arm, at least one cleaning means. Thus, a working method of the device consists in causing the protective casing to rotate to bring the viewing window to the cleaning means in order to clean the latter. The zone towards which the camera is blind is therefore advantageously used to receive a cleaning means.
Selon une autre caractéristique particulièrement avantageuse de l'invention, ladite platine est équipée à la base du bras d'éléments en saillie formant avec la surface extérieure du boîtier mobile en rotation une enceinte de protection. Un autre procédé de travail du dispositif consiste à faire réaliser une rotation du boîtier pour amener la fenêtre de visualisation dans ladite enceinte afin de la protéger.According to another particularly advantageous feature of the invention, said plate is equipped at the base of the projecting element arm forming with the outer surface of the rotating housing a protective enclosure. Another method of working the device is to rotate the housing to bring the viewing window into said enclosure to protect it.
Un autre procédé de travail consiste à intégrer une fonction de verrouillage et de déverrouillage juridique d'un masquage des images qui peut être traité soit localement (enregistreur embarqué dans le dispositif), soit par un dispositif de traitement sur demande de la justice.Another method of work consists in integrating a function of locking and unlocking legal image masking which can be processed either locally (on-board recorder in the device), or by a processing device on request of justice.

4 et 5, le dispositif de l'invention référencé D qui assure la gestion du fonctionnement et la mise en mouvement d'un moyen de prise de vues 100, est constitué — o —4 and 5, the device of the invention referenced D which provides the management of the operation and the setting in motion of a means of shooting 100, is constituted - o -
par un boîtier de protection 200 dudit moyen de prise de vues 100 qui est monté mobile en rotation selon un premier axe X par rapport à au moins un bras 310a solidaire d'une platine 300 qui est montée mobile en rotation selon un deuxième axe perpendiculaire Y au premier par rapport à un socle fixe 400. Comme illustrée, la rotation sur ces deux axes X et Y peut être réalisée à 360 degrés sans butée.by a protective case 200 of said camera means 100 which is rotatably mounted along a first axis X with respect to at least one arm 310a integral with a plate 300 which is rotatably mounted along a second perpendicular axis Y at first relative to a fixed base 400. As illustrated, the rotation on these two axes X and Y can be performed 360 degrees without stop.
Conformément à l'invention et selon le mode de réalisation illustré, ladite platine 300 comprend deux bras 310a et 310b entre lesquels évolue en rotation ledit boîtier de protection 200. Selon le choix technologique illustré, seul un bras 310a assure seul le guidage et la mise en mouvement en rotation selon l'axe X du boîtier de protection. Comme illustré, ledit boîtier de protection 200 comprend une fenêtre 210 devant laquelle l'objectif 110 du moyen de prise de vues 100 est installé. Cette fenêtre 210 est fermée par une plaque 211 de matériau transparent qui adopte ici la forme d'un disque. Le boîtier de protection est donc équipé d'une fenêtre fermée par une vitre à surface plane.According to the invention and according to the illustrated embodiment, said plate 300 comprises two arms 310a and 310b between which rotates said protective casing 200. According to the technological choice illustrated, only one arm 310a alone ensures the guiding and in rotation movement along the X axis of the protective case. As illustrated, said protective housing 200 includes a window 210 in front of which the objective 110 of the imaging means 100 is installed. This window 210 is closed by a plate 211 of transparent material which here adopts the shape of a disk. The protective case is therefore equipped with a window closed by a flat-surface pane.
Le boîtier de protection 200 forme, selon le mode de réalisation préféré illustré, une enveloppe cylindrique fermée autour du moyen de prise de vues 100 et dont une portion angulaire comporte une fenêtre 210 pour accueillir le disque de protection 211. Le volume intérieur du boîtier de protection 200 est aménagé pour accueillir un moyen de prise de vues 100 de forme quelconque. A cette fin, il est équipé de moyens de maintien en position 220 dudit moyen de prise de vues .The protective casing 200 forms, according to the preferred embodiment illustrated, a cylindrical envelope closed around the imaging means 100 and an angular portion of which comprises a window 210 for accommodating the protective disk 211. The interior volume of the housing protection 200 is arranged to accommodate a means of shooting 100 of any shape. To this end, it is equipped with holding means in position 220 of said camera means.
En outre, le fait que la surface de protection soit plane permet d'accueillir tout dispositif de prise de vues comportant un zoom de puissance quasi-illimitée.In addition, the fact that the protective surface is flat can accommodate any shooting device with a zoom of almost unlimited power.
Son champ visuel n'est limité que par la présence du socle 400 ou de la base de la platine 300 dont le volume n'empêche pas l'objectif de la caméra d'aller au-delà de 1 'horizontale.Its visual field is limited only by the presence of the base 400 or the base of the plate 300 whose volume does not prevent the camera's objective from going beyond 1 'horizontal.
Selon une caractéristique particulièrement avantageuse de l'invention, la disposition et les dimensions du moyen de prise de vues 100 par rapport à la disposition et aux dimensions de la platine 300 et du socle 400 (qui ne supporte pas de dôme), disposition notamment définie par la longueur du bras à l'extrémité duquel est guidé en rotation ledit moyen de prise de vues 100 contenu dans le boîtier de protection 200, définissent un champ de visibilité d'au moins deux cent soixante dix degrés. Le champ de vision proposé par le dispositif D de l'invention définit donc une sphère partielle de vision amputée d'un cône de "cécité" correspondant à la présence de la platine 300 et du socle 400, cône présentant un angle maximal de quatre-vingt dix degrés. Étant donné que conformément à l'invention, le moyen de prise de vues 100 n'est pas limité dans ses capacités de zoom (sauf par des considérations techniques), le diamètre de ladite sphère de vision est susceptible de varier et surtout de s'agrandir.According to a particularly advantageous characteristic of the invention, the arrangement and the dimensions of the imaging means 100 with respect to the arrangement and the dimensions of the plate 300 and the base 400 (which does not support a dome), a particularly defined arrangement by the length of the arm at the end of which is guided in rotation said means of shooting 100 contained in the protective case 200, define a field of view of at least two hundred and seventy degrees. The field of vision proposed by the device D of the invention thus defines a partial sphere of vision amputated from a cone of "blindness" corresponding to the presence of the plate 300 and the base 400, cone having a maximum angle of twenty ten degrees. Since according to the invention, the shooting means 100 is not limited in its zooming capabilities (except by technical considerations), the diameter of said sphere of vision is likely to vary and especially of enlarge.
En outre, comme illustrée et conformément à l'invention ledit socle est préformé pour ne pas constituer un obstacle lorsque la caméra dépasse le plan horizontal. POur ce faire son volume a été réduit. A cet effet, la platine 300 supportant les bras 310a et 310b est préformée de bords biseautés de façon à diminuer le plus possible l'obstacle visuel qu'elle pourrait constituer et ouvrir ainsi l'angle de vision vers le socle. Ainsi, selon le mode de réalisation illustré, l'angle du cône de "cécité" est largement inférieur à quatre vingt dix degrés augmentant ainsi les capacités de vision du dispositif D.In addition, as illustrated and in accordance with the invention said base is preformed to not constitute an obstacle when the camera exceeds the horizontal plane. To do this its volume has been reduced. For this purpose, the plate 300 supporting the arms 310a and 310b is preformed with beveled edges so as to reduce as much as possible the visual obstacle that it could constitute and thus open the viewing angle to the base. Thus, according to the illustrated embodiment, the angle of the cone of "blindness" is much less than ninety degrees thus increasing the vision capabilities of the device D.
La puissance du zoom et les capacités de résolution du moyen de prise de vues 100 vont en adéquation avec la précision des mouvements que propose le dispositif D de 1 ' invention .The power of the zoom and the resolution capabilities of the shooting means 100 are in line with the precision of the movements that the device D of the invention offers.
A cette fin, le dispositif D met en œuvre des caractéristiques d'entraînement, de suivi d'entraînement et de commandes spécifiques.For this purpose, the device D implements training characteristics, training follow-up and specific commands.
Ainsi, les mouvements de rotation sont assurés pour chaque axe par un moteur pas à pas . Le mouvement de rotation selon l'axe X est mis en œuvre par le moteur 320 qui est logé dans le bras 310a. Le mouvement de rotation selon l'axe Y est mis en œuvre par le moteur 330 qui est logé dans la platine 300. Ces moteurs pas à pas atteignent une précision de déplacement de l'ordre du dixième de degré. De même, la vitesse qui peut être pleinement exploitée de par l'absence de butée peut aller jusqu'à un tour par seconde sur les deux axes .Thus, rotational movements are provided for each axis by a stepping motor. The rotational movement along the X axis is implemented by the motor 320 which is housed in the arm 310a. The rotational movement along the Y axis is implemented by the motor 330 which is housed in the plate 300. These stepper motors achieve a displacement accuracy of the order of a tenth of a degree. Similarly, the speed that can be fully exploited by the absence of stop can go up to one turn per second on both axes.
Afin de disposer de l'information de la position angulaire réelle de la platine selon l'axe Y ou du boîtier de protection selon l'axe X, les mouvements de rotation sont suivis pour chaque axe par un codeur. Pour ce faire, chaque moteur 320 et 330 met en mouvement un pignon respectivement 321 et 331 qui, au moyen d'un lien souple, assure la rotation de l'axe d'un codeur respectivement 322 et 332. Le codeur permet de retourner au sous-ensemble de commande gérant les mouvements du dispositif D l'exacte position angulaire prise par les sous-ensembles auxquels leur axe sont cinématiquement liés. Le codeur permet donc de mettre à disposition l'information concernant la position angulaire même si le mouvement n'est pas généré par la commande des moteurs (mouvement accidentel, choc, forçage volontaire ou non des deux axes etc...).In order to have the information of the actual angular position of the plate according to the Y axis or of the protection box along the X axis, the rotational movements are tracked for each axis by an encoder. To do this, each motor 320 and 330 sets in motion a pinion respectively 321 and 331 which, by means of a flexible link, rotates the axis of an encoder respectively 322 and 332. The encoder makes it possible to return to control subassembly managing the movements of the device D the exact angular position taken by the subsets to which their axis are kinematically linked. The encoder thus makes it possible to provide the information concerning the angular position even if the movement is not generated by the control of the motors (accidental movement, shock, deliberate forcing or not of the two axes, etc.).
La présence des codeurs permet d'exploiter la précision de positionnement des moteurs (au dixième de degré) ce que ne permet pas les dispositifs de l'art antérieur.The presence of the encoders makes it possible to exploit the positioning accuracy of the motors (at a tenth of a degree) which is not possible with the devices of the prior art.
Les commandes, l'alimentation et les informations d'entrée et sortie sont transmises au niveau des articulations au moyen de joints tournants ou collecteurs 323 et 333. L'utilisation de ces collecteurs évite la présence de câbles susceptibles de gêner les mouvements de rotation à 360° sans butée sur les deux axes X et Y des différents sous-ensembles.The controls, the power supply and the input and output information are transmitted at the joints by means of rotating or collector seals 323 and 333. The use of these collectors avoids the presence of cables likely to hinder the movements of the joints. 360 ° rotation without stop on the two X and Y axes of the different subassemblies.
L'ensemble de ces caractéristiques contribue à une exploitation optimale des capacités de vélocité dans le repositionnement du moyen de prise de vues 100. L'absence de limitation quant à la course et au sens de rotation permet au dispositif de choisir la course angulaire la plus courte pour disposer d'une vue en urgence. L'information relayée par les codeurs permet d'assurer le retournement éventuel de l'image.All of these features contribute to an optimal exploitation of the velocity capabilities in the repositioning of the camera means 100. The absence of limitation as to the stroke and to the direction of rotation allows the device to choose the most angular stroke. short to have an emergency view. The information relayed by the encoders ensures the eventual reversal of the image.
L'ensemble de ces caractéristiques contribue également à une exploitation optimale des capacités de zoom que ne limite plus le choix de moyen de protection du moyen de prise de vues. Néanmoins, la demanderesse a imaginé d'utiliser les capacités de précision et de variation de la distance focale des moyens de prise de vues que peut exploiter efficacement le dispositif de l'invention, afin d'assurer la prise de vue d'éléments présents dans le champ de visualisation du moyen de prise de vues sans réaliser de mise en mouvement de ce dernier ce qui contribue à l'économie et donc à l'augmentation de durée de vie des sous-ensembles participant aux mouvements .All of these features also contribute to an optimal use of zoom capabilities that no longer limits the choice of means of protection of the medium of shooting. Nevertheless, the Applicant has imagined using the precision and variation capabilities of the focal length of the shooting means that the device of the invention can effectively exploit in order to ensure the shooting of elements present in the field of view of the shooting means without realizing the setting in motion of the latter which contributes to the economy and therefore the increase in life of the subsets participating in the movements.
L'adéquation entre précision de mouvement et précision de l'image avec des moyens de prise de vues dont la résolution évolue vers les dix millions de pixels permet d'envisager au moyen de sous-ensembles électroniques contenus dans le dispositif, les applications et procédés de travail suivants : - détection d'activité, d'inactivité de mouvement,The match between precision of motion and accuracy of the image with imaging means whose resolution evolves towards ten million pixels makes it possible to envisage by means of electronic subassemblies contained in the device, the applications and processes working conditions: - activity detection, motion inactivity,
- poursuite d'une cible détectée et/ou pré définie,- tracking a detected and / or pre-defined target,
- traitement de l'image par zone d'intérêt (zoom numérique sur une partie de l ' image sans mouvement moteur) avec une résolution d'environ cinq cent mille pixels transmis, - intégrer une fonction de verrouillage et de déverrouillage juridique d'un masquage des images qui peut être traité soit localement (enregistreur embarqué dans le dispositif), soit par dispositif de traitement sur demande de la justice,- image processing by area of interest (digital zoom on a part of the image without motor movement) with a resolution of about five hundred thousand pixels transmitted, - integrate a function of locking and unlocking a legal hiding images that can be treated either locally (on-board recorder) or by processing device at the request of the courts,
- embarquement de fonctionnalités jour/nuit à intégration lente des photons venant en association avec un déplacement lent du dispositif de prises de vues (par exemple un tour pour plusieurs heures) .- Loading day / night features slow integration of photons coming in association with a slow movement of the camera (for example a tour for several hours).
Le bras 310b forme un volume libre susceptible de contenir les susdits sous-ensembles électroniques. La fenêtre de protection fermant le boîtier de protection du dispositif de l'invention nécessite comme pour les dispositifs de l'art antérieur d'être nettoyée régulièrement. Les recherches de la demanderesse ont permis d'aboutir à la conception d'un dispositif de nettoyage automatique particulièrement judicieux.The arm 310b forms a free volume capable of containing the aforesaid electronic subassemblies. The protection window closing the protective case of the device of the invention requires as for the devices of the prior art to be cleaned regularly. The applicant's research led to the development of a particularly judicious automatic cleaning device.
Conformément à l'invention, ladite platine 300 comprend au niveau de la base du bras 310a, au moins un moyen de nettoyage 500. Selon le mode de réalisation illustré, ce moyen de nettoyage 500 se situe entre les deux bras 310a et 310b. Ainsi, le nettoyage peut être réalisé lorsque le boîtier de protection 200 réalise une rotation de façon à orienter la fenêtre 210 vers le moyen de nettoyage c'est à dire ici lorsque la fenêtre 320 passe entre la base des deux bras 310a et 310b. Le moyen de nettoyage 500 peut être constitué par une buse de projection de fluide de nettoyage (tel un liquide ou de l'air puisé) associé ou non à des moyens de frottement tels ceux illustrés en figure 4.According to the invention, said plate 300 comprises at the base of the arm 310a, at least one cleaning means 500. According to the illustrated embodiment, the cleaning means 500 is located between the two arms 310a and 310b. Thus, the cleaning can be performed when the protective housing 200 rotates so as to orient the window 210 to the cleaning means that is to say here when the window 320 passes between the base of the two arms 310a and 310b. The cleaning means 500 may consist of a nozzle for spraying cleaning fluid (such as a liquid or pulsed air) associated or not with friction means such as those illustrated in FIG. 4.
Ces moyens de frottement sont constitués par une brosse 510 et par une lèvre de frottement ou lame en caoutchouc telle une lèvre d'essuie-glace. Telle qu'illustrée, une rotation du boîtier de protection 200 selon son axe X permet à la fenêtre 210 d'être brossée et/ou essuyée ou vice-versa selon le sens de rotation et selon le fait que la rotation est complète où qu'elle s'arrête entre la brosse 510 et la lame 520 dans la position illustrée en figure 5. Le dispositif D de l'invention dispose donc d'un moyen de nettoyage particulièrement efficace sans intervention extérieure.These friction means are constituted by a brush 510 and a friction lip or rubber blade such as a wiper lip. As illustrated, a rotation of the protective housing 200 along its axis X allows the window 210 to be brushed and / or wiped or vice versa in the direction of rotation and according to the fact that the rotation is complete or that it stops between the brush 510 and the blade 520 in the 5. The device D of the invention therefore has a particularly effective cleaning means without external intervention.
Selon une autre caractéristique particulièrement avantageuse de l'invention, la base des bras est utilisée d'une autre façon. En effet, comme illustrée, ladite platine 300 est équipée à la base du bras, d'éléments en saillie venant en contact avec ledit boîtier 200 mobile en rotation et formant avec la surface extérieure de ce dernier un volume fermé. Selon le mode de réalisation illustré, ces éléments en saillie sont constitués par ladite brosse 510 et ladite lame 520 qui, lorsque la fenêtre 210 se trouve orientée vers la base des bras 310a et 310b, encadrent et protègent dans le volume fermé ladite fenêtre 210 dans la position illustrée en figure 5.According to another particularly advantageous feature of the invention, the base of the arms is used in another way. Indeed, as illustrated, said plate 300 is equipped at the base of the arm, projecting elements coming into contact with said housing 200 rotatable and forming with the outer surface thereof a closed volume. According to the illustrated embodiment, these projecting elements are constituted by said brush 510 and said blade 520 which, when the window 210 is oriented towards the base of the arms 310a and 310b, surround and protect in the closed volume said window 210 in the position illustrated in Figure 5.
Sur cette base, la demanderesse a imaginé un procédé de fonctionnement remarquable en ce qu'il consiste à faire réaliser une rotation du boîtier pour amener la fenêtre de visualisation 210 et la vitre 211 la fermant, dans ledit volume fermé afin de les protéger.On this basis, the Applicant has devised a remarkable operating method in that it consists in rotating the housing to bring the viewing window 210 and the window 211 closing, in said closed volume to protect them.
Ce mouvement d' auto-protection peut être provoqué par tout événement prédéterminé par l'exploitant comme par exemple, la détection de conditions climatiques empêchant un bon fonctionnement du dispositif. De même, la détection optique d'un élément se dirigeant à grande vitesse vers l'objectif du moyen de prise de vues peut également provoquer ledit mouvement .This self-protection movement can be caused by any event predetermined by the operator such as, for example, the detection of climatic conditions preventing proper operation of the device. Similarly, the optical detection of an element moving at high speed towards the lens of the camera can also cause said movement.
Selon le mode de réalisation illustré, les bras et le boîtier de protection sont préformés de façon à ce que les extrémités des bras reproduisent le diamètre du boîtier de protection 200. Le dispositif D adopte ainsi à son extrémité mobile une configuration compacte, aérodynamique et ne présentant pas d'épaulements, d'éléments en saillie ou d'anfractuosités. On comprend que le dispositif et ses procédés de travail, qui viennent d'être ci-dessus décrits et - -According to the illustrated embodiment, the arms and the protective housing are preformed so that the ends of the arms reproduce the diameter of the protective housing 200. The device D thus adopts at its mobile end a compact, aerodynamic configuration and does not with no shoulders, projecting elements or crevices. It is understood that the device and its work processes, which have just been described above and - -
représentés, l'ont été en vue d'une divulgation plutôt que d'une limitation. Bien entendu, divers aménagements, modifications et améliorations pourront être apportés à l'exemple ci-dessus, sans pour autant sortir du cadre de l'invention.represented, have been for the purpose of disclosure rather than limitation. Of course, various arrangements, modifications and improvements may be made to the example above, without departing from the scope of the invention.
Par exemple, bien que le mode de réalisation illustre un dispositif avec un boîtier de protection accueillant un seul moyen de prise de vues, les caractéristiques ci- dessus décrites s'appliquent également à des boîtiers ménagés pour accueillir plusieurs moyens de prises de vues éventuellement de technologies différentes associés ou non à au moins un capteur. For example, although the embodiment illustrates a device with a protective housing accommodating a single means of shooting, the above-described features also apply to housings arranged to accommodate several means of shooting possibly different technologies associated or not with at least one sensor.
