Definitions

  • the present invention relates to the field of urban furniture. More specifically it relates to methods and systems to detect objects in a space.
  • W02020084213 describes a people counting device. It comprises a sensor to detect people, such as a camera.
  • a problem is to guarantee the anonymity of the people counted.
  • This document solves the problem by defining a specific method to count people, including not furnishing information if the number is too low. Such solution therefore leads to a lack of information in some cases.
  • people tend not to accept to be captured by a camera in a public place.
  • a camera on such an urban furniture is usually vandalized.
  • the present invention concerns an urban furniture.
  • Such urban furniture comprises a display and a structure surrounding such display. It further comprises a lidar integrated in the structure.
  • a cover covers the lidar, such cover being transparent in the operating wavelength range of the lidar and opaque in the visible wavelength range.
  • the urban furniture further comprises communication means configured to send data from the lidar to a server, the communication means being hidden in the structure.
  • the present invention also concerns the use of such an urban furniture for object recognition and tracking.
  • FIG.1a illustrates an urban furniture, exemplified as a digital totem.
  • Fig.lb illustrates the same digital totem in an exploded view.
  • Fig.lc illustrates an alternative embodiment.
  • Fig.2 illustrates an urban furniture, exemplified as a bus shelter.
  • the present invention proposes an urban furniture.
  • urban furniture encompasses digital totem or kiosk, also referred to as advertising panel, as well as bus shelter. It could also consist of a candelabra for public lighting, a public restroom building, ...
  • the urban furniture comprises a display.
  • a display instead of a display, one or more posters made of paper or the like could be used.
  • the display could be onesided or two-sided viewable, meaning the display forecasts on one or two faces.
  • the urban furniture further comprises a structure configured to surround the display.
  • Such structure is usually made in a plastic or metallic material.
  • the urban furniture further comprises a lidar integrated in the structure.
  • Lidar is an acronym for “light detection and ranging”. It is sometimes called “laser scanning” or “3D scanning”.
  • the technology uses eye-safe laser beams to create a 3D- representation of the surveyed environment.
  • Operating wavelength of lidar compatible with the present invention is comprised between 750 and 1650nm (usually referred to as near-infrared range). More specifically, known operating wavelengths of currently produced lidars compatible with the present invention are 850nm, 905nm, 940nm, 1064nm, 1310nm, 1350nm, 1550nm, 1650nm.
  • An acceptable variance of 25nm around the nominal value of the wavelength may be considered, such that, for example, a wavelength range of 1525 to 1575nm may be accepted around the nominal value of 1550nm.
  • Lidar acquires anonymized data (i.e. no acquisition of biometric data like facial information or skin/hair color) which makes it naturally GDPR (General Data Protection Regulation) compliant, contrary to a camera. This key feature allows the installation of the system in a city without extensive authorizations and security protocols.
  • the urban furniture further comprises a cover covering the lidar.
  • the cover is transparent in the operating wavelength range of the lidar.
  • the cover is further opaque in the visible wavelength range. It therefore allows the lidar to operate efficiently while being hidden behind the cover, being then less exposed to vandalism.
  • the urban furniture further comprises communication means allowing the lidar to send data to a server. These communication means are hidden in the structure.
  • Non-limiting examples of communications means are a central unit connected to the lidar and able to transmit data through a wireless communication protocol to an external server, or such central unit equipped with a communication port in order to retrieve information manually, or any other communication mean known by the skilled in the art.
  • the cover has a transmission in the visible wavelength range of less than 1 %, preferably less than 0.1 %, more preferably less than 0.01 %.
  • the visible wavelength range is defined as from 380nm to 780nm.
  • the luminous transmittance represents the percentage of light flux emitted between wavelengths 380nm and 780nm which is transmitted through the cover.
  • the cover is understood to have a luminous transmittance of less than 1 %, preferably less than 0.1 %, more preferably less than 0.01 %. It allows the cover to hide the lidar placed behind.
  • the cover can be colored in the bulk, meaning that the material of the cover itself is colored in the visible wavelength range (while still being transparent at the operating wavelength range of the lidar).
  • the cover could also be printed (with an ink or an enamel) or coated (for example through plasma vapor deposition process or any other process known by the skilled in the art) in order to render it opaque in the visible wavelength range.
  • the cover comprises at least one glass sheet.
  • the glass sheet has a composition that is not particularly limited.
  • the glass sheet may be a soda-lime-silicate glass, an alumino-silicate glass, an alkali-free glass, a boro-silicate glass, ...
  • the glass sheet of the invention is made of a sodalime glass or an alumino-silicate glass.
  • the glass sheet according to the invention may be a glass sheet obtained by a floating process, a drawing process, a rolling process or any other process known to manufacture a glass sheet starting from a molten glass composition.
  • the glass sheet is a float glass sheet.
  • float glass sheet is understood to mean a glass sheet formed by the float glass process, which consists in pouring the molten glass onto a bath of molten tin, under reducing conditions.
  • the glass sheet preferably has a thickness comprised between 0.5mm and 6mm, more preferably between 1 mm and 4mm. Usual thickness for such glass sheet is 1 ,6mm, 2.1 mm, 3.1 mm or 4mm.
  • the at least one glass sheet has an absorption coefficient at the operating wavelength of the lidar of less than 15m -1 , preferably less than 10m -1 , even more preferably less than 5m’ 1 .
  • the absorption coefficient is used in the wavelength range from 750 to 1650nm.
  • the absorption coefficient is defined by the ratio between the absorbance and the optical path length traversed by electromagnetic radiation in a given environment. It is expressed in rrr 1 . It is therefore independent of the thickness of the material but it is function of the wavelength of the absorbed radiation and the chemical nature of the material.
  • the glass having an absorption coefficient at the operating wavelength of the at least one lidar of less than 15m’ 1 , preferably less than 10m’ 1 , even more preferably less than 5m’ 1 may be a soda-lime-silica glass, alumino-silicate, boro-silicate, ...

  • the glass may include other components, nature and adapted according to quantity of the desired effect.
  • a solution to obtain a very transparent glass in the near infrared, with weak or no impact on its aesthetic or its color, is to combine in the glass composition a low iron quantity and optionally chromium in a range of specific contents.
