Description

Title of the invention: Smart box for real-time detection and alert

[0001] The invention relates to a box, compatible with different media, making it possible to process video streams, including multispectral, to detect information of interest and alert the end user in real time. Technical field

[0002] 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. Prior art

[0003] The majority of cameras, such as video surveillance 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 people detection). A minority of cameras use multispectral sensors but without on-board processing. Statement of the invention

[0004] Thus, by transmitting only the information useful to the end user, our device according to the invention makes it possible to drastically reduce the transmission of video streams and their very energy-intensive storage, which is a growing problem inherent in the multiplication of systems using cameras. The invention has low energy consumption and is small in size, which allows it to be installed on numerous supports, such as, but not limited to, aerostats with a battery power supply, or fixed masts with a mains or solar panel power supply.

[0005] The system according to the invention mainly allows: • Acquire a multispectral video stream, • Process images in real time, possibly with on-board Artificial Intelligence, • Generate and transmit an alert containing in particular a visualization of the detected event, its geolocation, its dating, its precision, • Integrate into fixed supports or embedded systems, • Operate in an outdoor environment regardless of weather conditions, excluding exceptional climatic phenomena Brief description of the drawings

[0006] [Fig.l] represents the main constituent elements of the device of the invention and [Fig.2] represents a variant of this device.

[0007] With reference to [Fig.l], the device according to the invention uses a protective housing (1), of parallelepiped shape, with a closing cover (1a) allowing access to its components, for the purpose of repair or improvement, while guaranteeing at least IP64 compliance. Depending on its use case, the housing will be made of anodized alloy to better resist corrosion and shocks. It may be covered with thermal paint on the outside. The housing will also have mechanical interfaces (tapped holes) to install it on different supports such as a fixed mast or a drone nacelle. Optical portholes (7a) are installed on one side of the housing (1).

[0008] A connector (4), of the USB-C type, allows the connection of an external power supply or other equipment, such as a screen.

[0009] An optional battery (5) can be used to power the system in certain use cases such as aerial drones, or to guarantee operation in the event of a power cut from the external power supply via the connector (5).

[0010] An electronic card (2), which carries the processing software, is fixed inside the housing (1), and conductively connected to a dissipative surface. To carry out the video processing on its electronic chip, the card (2) recovers the images coming from the cameras via its connectors (such as USB, MIPI, Ethernet).

[0011] A radio module (3) for geolocation and multi-channel transmission transmits the alerts.

[0012] In the complete version of the system according to the invention, the fixing plate (6a) has different mechanical interface points allowing different cameras to be fixed. Therefore, in the case of use with several cameras (8), the latter can be co-aligned on this plate (6a) before being itself integrated into the housing (1).

[0013] In the variant [Fig.2], the optical subsystem, i.e. the plate (6a) and the cameras (8), is replaced by a video module (6b) for acquiring the video signal from cameras external to the housing (1). In addition, the portholes (7a) are replaced by closing plates (7b), guaranteeing the required sealing, and integrating the connectors for interfacing the cameras external to the video module (6b).

[0014] As a non-limiting example, the system will have a size of approximately 14cm in length, 12cm in width and 8cm in height, a weight of less than 1kg, and an average consumption of less than 10W. Its design is compatible with outdoor use in all weather conditions, except in exceptional climatic phenomena.

[0015] Examples

[0016] Our invention, due to its low weight, low volume and low consumption, 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.

Claims

Claims

1. The device, intended to process in real time on its electronic card (2), video streams acquired by integrated sensors (6a, 7a, 8) or external sensors (6b, 7b), and to transmit the extracted information on different channels (3), 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 (5), and thanks to its compact size (1, 1 bis).
