Description

Title of the invention: Real-time detection and alert device Technical field

[0001] The present invention relates to an on-board detection system, by video processing, and alert, multi-use (such as civil security, agriculture, defense), and multi-support (such as aerial drones or fixed masts) to alert the end user in real time of an event of interest to him. STATE OF THE ART

[0002] For the detection and emission of alerts, known solutions increasingly resort to the use of sensors. Typically, a camera continuously captures a video stream which is transmitted to a remote server for analysis. When a situation of interest is detected, the remote server triggers an alert. For example, one device is configured to identify the start of a fire. Another device may, for example, be configured to identify a person who is in a situation requiring the intervention of a rescue team.

[0003] These solutions prove to be costly in practice in terms of deployment and maintenance.

[0004] Thus, even though these solutions would make it possible to considerably increase the security of certain situations, they are in practice not very widespread.

[0005] An object of the present invention is therefore to propose a solution making it possible to limit or even eliminate at least some of the limitations of existing solutions.

[0006] An object of the present invention is to propose a solution to facilitate the deployment of detection solutions based on video stream analysis.

[0007] Other objects, features and advantages of the present invention will become apparent from a consideration of the following description and accompanying drawings. It is understood that other advantages may be incorporated. SUMMARY

[0008] To achieve this objective, according to one embodiment, a detection and alert device is provided, comprising a housing and an electronic card, embedding processing software, housed in the housing, the device being configured to process in real time on the electronic card video streams acquired by sensors integrated into the housing or external to the housing, and to transmit the extracted information on different channels, the housing further having mechanical interfaces to install it on different supports taken from a fixed mast or a drone nacelle.

[0009] Thus, the device offers great agility, allowing it to be installed on different supports and processing video streams coming from on-board or external sensors. The user thus has the possibility of using this device for a first application, by installing it on a first support and using first sensors, then, by using it for a second application by installing for example on a second support and possibly using other sensors.

[0010] Typically, the same device according to the invention can be used by the same professional intervention team:

[0011] - in periods of high fire risk for fire outbreak monitoring by being fixed on a fixed high point of a natural site. For this first use, a first type of sensor can be used, such as an optical camera operating in a first spectral band adapted to the detection of fire starts. This can for example be a camera external to the housing.

[0012] - in periods of low fire risk, for the search for victims while being placed on a drone gimbal. For this second use, a second type of sensor can be used, such as an optical camera operating in a second spectral band suitable for detecting individuals. This could, for example, be an infrared camera. This second type of camera can be integrated inside the housing in addition to the first, for example upon delivery from the factory.

[0013] It thus appears clearly that the same device can receive a more intense application throughout the year by being used for different missions by the same user, the same team of users or the same company.

[0014] Thus, a single team of users can acquire a single device that it can use for numerous applications, which makes it possible to considerably reduce the cost associated with observing the different uses.

[0015] Furthermore, the device is configured to transmit only useful information, including an alert with an image of the detection, to the end user. Thus, the device makes it possible to drastically reduce the transmission of video streams and their storage, which are very energy-intensive. However, in the context of the development of the present invention, it has been found that the transmission of video streams for processing by a remote server and their storage, even transiently for the duration of their processing, represents a significant part of the cost of using this type of solution.

[0016] The proposed device thus has the advantage of having very low energy consumption. It also makes it possible to considerably reduce the memory required for processing and storing the information since the latter is processed as the video stream is captured by the sensors and only the relevant video sequences are stored, preferably only the relevant images are processed and stored or sent.

[0017] According to an object, a device is provided, intended to process in real time on its electronic card, video streams acquired by integrated or external sensors, and to transmit the extracted information on different channels. The device is characterized by its capacity to be integrated on different vectors, such as aerial drones or fixed masts, thanks to its low consumption, with possible power supply by internal battery, and thanks to its compact size.

[0018] According to another object, a method of using the above device is provided, the method comprising:

[0019] - a first phase comprising a selection by the user of a first type of use of the device, the installation of the device on a first support and the use of the device on the first support and for this first use. The installation of the device on the first support can be carried out before or after the first selection.

[0020] - a second phase comprising, a selection by the user of a second type use of the device, and the use of the device for this second use.

[0021] According to one option, the second phase comprises, a detachment of the device from the first support, an installation of the device on a second support different from the first support. The second use is therefore carried out while the device is on the second support. The installation of the device on the second support can be carried out before or after the second selection. The detachment of the device can be carried out before or after the selection of the second use.

[0022] According to one option, the method comprises, after or before the selection of a second use, the addition of sensors comprising a step of connecting external sensors to connection ports carried by the housing.

[0023] According to one example, the proposed list of uses includes at least one of the following uses: fire detection, identification of an individual, monitoring of an urban or natural area, identification of a road, maritime or air accident situation, identification of an industrial accident or incident situation, presence of diseases on plants or crops, presence of boats for example in navigation or fishing zones subject to restrictions, presence of animals or species to be protected

[0024] According to one example, the support is taken from a fixed mast, a robotic arm, a drone nacelle, a support carried by an aircraft, a land vehicle or a maritime vehicle.

[0025] According to a purely optional example, the method comprises, after or before the selection of a second use, modifying, adding or removing integrated sensors connected to the electronic card of the device. Preferably, this modification or addition or removal is carried out in the factory or by specialized personnel who are not the end user of the product.

[0026] The user's selection of a type of use includes the connection, wired or wireless, of the box with a user terminal and the selection, on a graphical interface of the terminal, of a use from a list of proposed uses.

[0027] Preferably, the user terminal is a laptop or a smartphone.

[0028] The connection between the user terminal is made by one of the following communication modes: wired communication, Bluetooth, Wifi, satellite.

[0029] According to another object, a system is provided, comprising a device as described above, as well as a support configured to receive the housing, the support being taken from among a fixed mast, a robotic arm, a drone nacelle, an aerostat, an aircraft, a land vehicle or a maritime vehicle.

[0035] The drawings are given as examples and are not limiting of the invention. They constitute schematic representations of principle intended to facilitate the understanding of the invention and are not necessarily on the scale of practical applications. DETAILED DESCRIPTION

[0036] Before commencing a detailed review of embodiments of the invention, optional features which may optionally be used in combination or alternatively are set out below:

[0037] According to one example, the device comprises at least two locations for cameras housed in the housing.

[0038] According to one example, the device comprises a video module and the closure plates integrate connectors for interfacing cameras external to the video module.

[0039] According to one example, the device comprises a video module and the housing comprises connectors for interfacing cameras external to the video module.

[0040] According to one example, the device comprises portholes through which cameras arranged on the locations can capture a video stream.

[0041] According to one option, the housing can be configured so that the portholes can be replaced by closure plates, shaped to ensure sealing of the housing. According to one example, the device comprises a video module and the closure plates integrate connectors for interfacing external cameras with the video module.

[0042] Thus, the same device can easily be adapted to operate either with cameras integrated inside the housing, or with external cameras. This makes it possible to considerably reduce the cost of producing the housing, since the same housing can be used with different components and for different applications.

[0043] According to an example, the housing comprises at least one connector for connecting to the housing external cameras not housed in the housing.

[0044] According to one example, the electronic card is configured to retrieve images from cameras taken from among cameras housed in the housing or from cameras external to the housing.

[0045] According to one example, the device comprises at least one fixing plate comprising several mechanical interface points allowing different cameras to be fixed.

[0046] According to one example, the housing comprises a cover forming a single-piece assembly closed except for a lower opening, the housing comprising a lower face configured to close the opening, the internal face comprising at least one mechanical interface for fixing the housing to a plurality of supports.

[0047] According to one example, the card is configured to retrieve images from cameras taken from among cameras housed in the housing or cameras external to the housing.

[0048] According to one example, the system comprises a support on which the housing is installed by one of its mechanical interfaces, the support being taken from among a fixed mast, a drone nacelle, a robotic arm, an aircraft, an aerostat, a land vehicle, a maritime vehicle.

[0049] According to one example, the radio module is configured to transmit alerts.

[0050] According to one example, the device comprises at least one fixing plate featuring multiple mechanical interface points for attaching different cameras.

[0051] According to one example, the device preferably comprises, inside the housing, sensors taken from a temperature sensor, a humidity sensor, a brightness, a satellite geolocation module of the GPS (Global Positioning System or Galileo) type

[0052] It is specified that, in the context of the present invention, the terms “on”, “overcomes”, “covers”, “underlying”, “opposite” and their equivalents do not necessarily mean “in contact with”.

[0053] In the present patent application, the term "solidary" used to qualify the connection between two parts means that the two parts are linked / fixed relative to each other, according to all degrees of freedom, unless explicitly specified differently.

[0054] With reference to Figures 1 and 2, an example of a detection and alert device according to the invention will now be described.

[0055] The device comprises a housing 1 and an electronic card 2 housed in the housing. The device is configured to process in real time on the electronic card 2 video streams acquired by sensors 8a integrated into the housing 1 or external 8b to the housing 1. The device is configured to transmit the extracted information on different channels 3.

[0056] The device is very energy efficient. It is small in size, which allows it to be installed on many supports, such as, but not limited to, aerostats with battery power, or fixed masts with mains or solar panel power.

[0057] The device according to the invention mainly makes it possible to:

[0058] - acquire a multispectral video stream,

[0059] - process images in real time, possibly with Artificial Intelligence embedded in the box 1, preferably embedded in the electronic card.

[0060] - generate and transmit an alert containing at least one of a visualization of the detected event, its geolocation, its dating, its precision,

[0061] - integrate on fixed supports or embedded systems,

[0062] - operate in an outdoor environment regardless of conditions weather.

[0063] Preferably, the optical sensors have different detection spectral bands from each other. Thus, the detection is made more precise and suitable for a higher number of uses.

[0064] The majority of cameras used in known solutions, such as video surveillance type cameras, only use sensors in the Red / Green / Blue bands, or even in the infrared thermal band, sometimes with on-board processing but specialized for limited use cases (such as the detection of people). Advantageously, the invention provides for equipping the housing with cameras using multispectral sensors in different bands and with on-board processing. This combination of cameras using multispectral sensors in different bands and with on-board processing is not found in existing solutions.

[0065] The housing 1 has mechanical interfaces for installing it on different supports taken from a fixed mast, a drone nacelle, a robotic arm, a support carried by an aircraft or an aerostat, a maritime or terrestrial vehicle. The mechanical interfaces comprise for example tapped holes for installing it on these different supports.

[0066] According to one example, it has a parallelepiped shape, with a closing cover 1 bis allowing access to its components, for example, for the purpose of repair or improvement, while guaranteeing good sealing against water and humidity.

[0067] Depending on its use case, the housing may be made of anodized alloy to better resist corrosion and shocks. It may also be made of reinforced plastic, for example reinforced with a metal such as aluminum. It may be covered with thermal paint on the outside in order to limit or even prevent the propagation of heat inside the housing.

[0068] Optical ports 7a are configured to allow the video stream sensors embedded inside the housing 1, typically cameras 8a, to be protected inside the housing while capturing a video stream outside the housing. Preferably, the optical ports 7a are installed on one side of the housing 1.

[0069] The device comprises at least one connector 4, of the USB-C type, configured to connect an external power supply or other equipment, such as a screen. The device also comprises an optional battery 5, possibly making it possible to power the device in certain use cases such as aerial drones, or to guarantee operation in the event of a cut in the external power supply via the connector 5.

[0070] The electronic card 2, which embeds the processing software, is fixed inside the housing 1. It is designed to evacuate its heat dissipation. To carry out the video processing on its electronic chip, the card 2 recovers the images coming from the optical sensors via its connectors (such as USB, MIPI, Ethernet).

[0071] The housing 1 is configured to connect additional, external optical sensors, for example to have a spectral band different from that offered by the cameras 8a embedded in the housing 1. Thus, according to one option, the housing 1 also comprises connectors 7b configured so that the user connects external cameras 8b to the housing 1.

[0072] The housing 1 also comprises a radio wave transmission module 3 and a geolocation module. Preferably, the transmission module 3 is multi-channel. It transmits the alerts. According to one example, and as illustrated in FIGS. 1 and 2, the transmission module 3 and the geolocation module form a single module. The alerts can be sent to a user terminal 100, for example a smartphone or a laptop. They can also be sent to a remote server 200. Furthermore, it is provided that these alerts are sent to a plurality of user terminals, for example the smartphones of people concerned by the alert, for example people located in a given area or able to intervene for a given type of event. This alert transmission can be done by wired or wireless communication 101, 201 (4G, 5G, Wifi, UMTS, Ethernet, satellite etc.) The alert is sent with geolocation information of the event for which an alert is sent.

[0073] Advantageously, the radio module 3 also sends one or more photos taken by the cameras 8a, 8b. Preferably, the device does not transmit a video stream but only one or more photos characteristic of the event for which an alert is sent. This makes it possible to reduce its energy consumption as well as the cost linked to the transmission of a large volume of information.

[0074] In one version of the device, the fixing plate 6a has different mechanical interface points for fixing different cameras 8a. Therefore, in the case of use with several cameras 8a, the latter are co-aligned on this plate 6a before being itself integrated into the housing 1. This makes it easier to assemble the device and therefore to reduce its production cost. Furthermore, this makes it very easy to customize the device, in particular by integrating optical sensors adapted to the applications desired by the customer, while having an identical manufacturing process and housing for varied applications.

[0075] [Fig.2] illustrates a variant. The optical subsystem, i.e. the plate 6a and the cameras 8a, is replaced by a video module 6b making it possible to acquire the video signal from cameras 8b external to the housing 1. In addition, the portholes 7a are closed. They are for example replaced by closing plates 7b configured to ensure sealing. These closing plates may be opaque to solar radiation. According to an advantageous embodiment, these closing plates integrate connectors making it possible to interface the external cameras with the video module 6b.

[0076] Thus, from the same housing comprising orifices on the front, it is possible either to have portholes for the use of cameras embedded in the housing, or to close these portholes and use them as communication ports. This makes it possible in particular to reduce the cost price.

[0077] As illustrated in the examples of Figures 1 and 2, the housing 1 has a container 10a configured to house the internal components of the housing. The container 10a defines an opening 10b through which the internal components are inserted. The upper opening 10b is configured to be covered by a cover 10c.

[0078] [Fig.4] illustrates a variant of devices. This variant can be combined with all the embodiments described above. In this variant, the housing 1 forms a cover 11 that is entirely closed except for one face, here the lower face If. The cover 11 forms a single piece, obtained by welding, folding, 3D printing. In this example, this cover 11 has five faces la-le, ensuring between them a perfect seal. The sixth face of this 3D volume forms an opening through which the various internal components of the housing 1 can be inserted. This opening is closed by the sixth face forming here the lower face If or the base of the housing 1. The lower face If comprises the members 1g of mechanical interface with a support for fixing the housing 1 to the support. These are holes for the passage of screws that screw into the support. This embodiment makes it possible to greatly simplify the sealing.In fact, it is sufficient to place a seal at the interface between the cover 11 and the lower face If in order to protect the interior of the housing 1 from humidity and water. Furthermore, this embodiment makes it possible to greatly simplify the assembly of the device.

[0079] In this example, a cap 12 is provided on each of the portholes 7a in order to protect them from direct sunlight and from water flow which could prematurely dirty the porthole 7a.

[0080] In the top view, the cover 11 is covered with the device 1. The internal components housed inside the housing 1 can be seen there. In this example, the cameras 7a, the electronic card 2, the radio communication module 3, the fixing plates 6a of the cameras 7a can be seen there. Advantageously, there is also a location card 9 with an inertial unit configured in particular for the geolocation function. The housing 1 can also have a storage card 13, of the SSD type, among other things for the embedded software. The latter can then be "booted" (i.e. loaded for its execution), at each (re)start, on the electronic card 2.

[0081] By way of non-limiting example, the system will preferably have a volume of less than 3000cm3, preferably a weight of less than 1kg, and an average consumption of less than 15W. Its design is compatible with outdoor use in all weather conditions.

[0082] Due to its low weight, its small volume, its low consumption, it is particularly suitable as a payload for on-board systems such as wired aerostats or aerial drones, to alert in real time on events of interest which require several spectral bands (in the visible or infrared spectrum).

[0083] For example, the device is equipped with a camera whose spectrum is configured to allow the detection of smoke or flames during the day, typically a detection spectrum in the visible wavelengths as well as another sensor having a different detection spectrum, for example in infrared, to detect people or animals at night with a thermal sensor.

[0084] With reference to [Fig.3] as well as to figures 1, 2 and 4, an example of a method of using the device according to the invention will now be detailed.

[0085] A technician, and advantageously the user himself, interacts with the device via a graphical interface, implemented for example on a user terminal such as a computer 100, 200 or a smartphone 100. This interaction 101, 201 can be carried out at a relatively close distance, for example by Bluetooth or by wifi, or at a more distant distance by wireless or wired connection. The user selects 301 a first use of the device. Before or after this selection 301, he installs 302 the device on a first support. The software of the electronic card checks that the sensors relevant for this use are present and activates them as needed. The electronic card then controls the different sensors, receives their data, typically video streams, processes the images, and sends an alert if necessary. Preferably one or more images are sent in the alert.The device can thus ensure this first use.

[0086] When the user wishes to carry out another type of observation or detection, he can initiate a second phase. During this second phase, he selects 311 a second type of use via the graphical user interface. Before or after this selection, and optionally, he uninstalls 312 the device from the support on which it was previously fixed. Optionally, and before or after the previous steps, he can modify 313 the sensors to which the electronic card 2 is connected. For example, the user can connect external cameras 8b to the device. To do this, he can connect the external cameras 8b to the connectors 7b provided on the housing 1. Modify here means that he can add sensors. For example, he can add cameras 8b to the cameras 8a already present, these cameras 8b and 8a having, for example, different spectral bands or different zoom or field width capabilities.This further increases the versatility of the device without having to open the housing 1 and compromise its sealing. If this second use requires a change of support, then the user installs 314 the device on a second support. The second use 315 can begin. The electronic card 2 controls the sensors relevant for this second use.

[0087] Thus, it clearly appears that this device and its method of use make it possible to use this device in a particularly simple manner, for varied applications, and without requiring particular expertise when changing use.

[0088] A particular example of embodiment will now be described. This example, like the previous examples, is in no way limiting and numerous variations may be made.

[0089] Case

[0090] The housing may have at least some of the following additional features.

[0091] It has a cap system to prevent water droplets on the Camera ports. The camera protection ports are secured with a gasket to ensure watertightness. In the version without a camera, they are replaced by waterproof caps. The electronic boards are secured inside the housing, slightly raised in case of water condensation at the bottom of the housing.

[0092] The dimensions of the case are suitable for being mounted on a drone nacelle or supported by a turret or mast. The maximum reference size: 237x184x288 centimeters.

[0093] The software embedded in the box 12 controls the entire device, actuators and external devices (motors, IP / USB camera, etc.) in real time. This software is compatible with low-power electronic chips (CPU, GPU, TPU). The modular software solution is composed of several interdependent bricks that integrate seamlessly. This thus offers a complete and optimized solution that allows management of sensors and consumption modes, processing and data exchange.

[0094] Several bricks will now be detailed.

[0095] Image acquisition: this software brick controls the cameras connected to the device. It acquires images in real time for processing by the AI. To acquire a multispectral image, from two cameras, the image capture is synchronized very precisely. Then a correction and a superposition of the images are carried out in order to create a multispectral "cube", the number of spectral bands is then greater than 3. In the context of an acquisition with an external IP camera, the device will use the input points of the external device.

[0096] AI: this building block makes decisions in real time: very low latency. It uses local data. The data is all processed internally and then destroyed, with the exception of detections, thus preserving data confidentiality. Typically, the processed images are destroyed, except those that characterize an alert and are sent or stored. This AI is frugal in data and resources necessary for its operation. Remotely, the client can modify the sensitivity of the AI ​​and update it. This building block is an ideal solution for applications requiring high responsiveness.

[0097] Geolocation: this brick is configured to precisely determine the geographical position of an event detected by the “Intelligence” software brick. Artificial” in an image from a camera, in real time and with great reliability.

[0098] Acquisition _ sensors: this sensor data acquisition technology building block is designed to collect accurate data in real time. It interfaces with different types of sensors and communications protocols and processes the data using advanced signal processing algorithms. This building block allows data to be filtered, anomalies to be detected and measurement errors to be compensated. Depending on the weather conditions (temperature, humidity and brightness) the device will autonomously decide to change the sensitivity threshold of the AI, to go into standby (very low power consumption), to turn off a camera if it is dark, etc.

[0099] Actuator control (PTZ, Nacelle ...): this innovative brick attaches an action (rotate, zoom, center ...) to the results of the "AI" brick. Indeed, depending on the detection results and if the box 1 is connected to positioning actuators, it will position the detected object in the center of the image and be able to zoom according to the capacity of the camera used.

[0100] Transmission: this innovative brick transmits alerts immediately after detection. Indeed, if all useful data is collected (image, detection, geolocation of the object), the alert is transmitted by the available means of communication (4G / 5G, Wifi, Ethernet or Satellite). Since transmission is a major energy consumption item, it is therefore reduced as much as possible to sending alerts and other data strictly necessary for the end user.

[0101] Operational control: this technological brick for monitoring the good health of the device or "Health check" in English, is designed to ensure continuous monitoring of the integrity and performance of the software system. Integrated into a set of several bricks, this brick makes it possible to proactively identify anomalies, malfunctions and potential failures, thus guaranteeing high availability and optimal reliability of the system. It constitutes an essential tool for optimizing the maintenance and lifespan of the software system.

[0102] HMI: this software brick notifies users 100, 200 of an alert in real time. The user can view and validate these alerts. It also allows, and in a non-limiting manner, to configure and calibrate the cameras (technician side) and to modify AI parameters (e.g. sensitivity threshold).

[0103] Power management: this software brick optimizes the energy consumed by the device, including an accumulator and recharging options via solar panels, mains, POE. This ensures prolonged autonomy without human intervention. It implements different consumption modes, in order to ensure maximum autonomy of the system by guaranteeing the proper functioning of the device. In Combining battery management, solar energy monitoring and deep sleep features, this brick allows energy consumption to be adapted in real time to available resources. It is a very advantageous solution for adapting to different use cases, both over a long lifespan and for low consumption.
