Definitions

  • the present invention relates to a radial objective arrangement for generating an optical image of a detection area, in particular a radial objective arrangement for an all-round optical sensor.

  • the previously known all-round camera has motion sensors, which are arranged laterally in a housing jacket of the panoramic camera and are aligned in such a way that a range of 360 ° relative to an optical axis of the panoramic camera is detected. If a motion sensor indicates a movement, the panoramic camera is triggered and the image information reflected via the mirror is converted into digital data by a semiconductor chip of the panoramic camera.
  • a disadvantage of the known all-round camera is that said movement sensors must be provided for the operation in order to ensure detection of an object in the detection area can.
  • DE 600 37 040 T2 discloses a radial objective arrangement according to the preamble of patent claim 1.
  • a disadvantage of the radial objective arrangement known from this document is the inaccurate positioning of the light collecting unit, which is designated in the document as a "general parabolic omnidirectional mirror" and is designated in the figures there by the reference numeral 112. This mirror is designed as a separate component and must Because of this imprecise positioning, an image projected onto the viewing surface is blurred and / or incomplete.
  • the radial lens assembly includes the central light-deflecting unit (sometimes referred to simply as a "light-deflecting unit" in the description of the present invention) that is configured and arranged to break and initially conduct directionally incoming light from the detection area.
  • the detection area is, for example, an area lying above to / and / or below the radial objective arrangement. If, for example, a center of the radial objective arrangement is considered to be the center of a spherical coordinate system, the detection area comprises coordinates which have an arbitrary azimuth angle between -180 ° to +180 ° and a polar angle between approximately 0 ° to 90 ° and / or 90 ° to 180 °.
  • the detection area starts at the outer lateral surfaces of the central light deflection unit.
  • the detection area extends below to / and / or above the central light deflection unit, the incident light being incident on the outer surface of a respective one of the plurality of optical rings.
  • the light collection unit is configured and arranged to receive light transmitted by the central light deflection unit and to project it onto an observation surface of the light collection unit.
  • the light collecting unit is configured, for example, as an optical cone, wherein a base of the cone forms the observation surface. From the observation area, the light is preferred fed to an evaluation unit, which is designed, for example, to measure a brightness and / or to detect a brightness change.
  • the cone base of the cone is, for example, circular. Depending on the field of application, however, other shapes for the conical base come into consideration. For example, a substantially elliptical cone base is useful for detecting a playing field of a sports stadium.
  • the number of optical rings of the light collection unit functions as a lens of the radial lens assembly.
  • the optical rings are arranged such that the light coming from the detection area is incident on the respective outer surface of the mantle.
  • the central light deflection unit may in particular also comprise only a single optical ring.
  • the central light deflection unit and the light collection unit are formed from a monolithic piece of material.
  • the monolithic piece of material of the radial objective arrangement thus comprises the central light deflection unit and the light collection unit. Both the light gathering unit and the central light deflecting unit are formed in the same, single and continuous (monolithic) piece of material.
  • the monolithic piece of material may, for example, be a piece of plexiglass that has been processed to form the central light collecting unit and the light deflecting unit, for example by a grinding process.
  • the central light deflection unit and the light collection unit are exactly aligned with each other. All light coming out of the detection area is projected exactly onto the observation surface of the light collecting unit.
  • the central light deflection unit and the light collection unit have a common optical axis which runs along a z-axis of the radial objective arrangement and comprises a respective center of the number of optical rings. This aspect will be explained further below.
  • the radial objective arrangement according to the invention is further distinguished by a simple lens design, which can advantageously be integrated in an optical sensor and / or in a communication sensor.
  • the radial objective arrangement according to the invention has no moving optical parts. Due to the configuration of the central light deflection unit and the light collection unit in the monolithic piece of material, distance relationships, in particular between the light collection unit and the light deflection unit, are fixed and variable.
  • the radial objective arrangement according to the invention preferably comprises exclusively the light deflection unit and light collection unit formed in the monolithic piece of material.
  • the radial lens assembly is thus completely rigid and insensitive to shocks. In addition to the monolithic piece of material in which the Lichtumlenkmaschine and the Lichtsammeimaschine are formed, no further components are necessary to produce the optical image.
  • moving lenses or moving cameras have been used in the prior art to produce all-round views.
  • lenses are used which, for example, can detect 120 ° wide angles.
  • three of these lenses would be necessary to create a 360 ° view.
  • the radial lens assembly according to the invention is also characterized by a long service life, since the local strength causes both the radial lens assembly and the optical elements therein, in contrast to moving parts no wear. Because no movable optical elements are provided, well-founded measurement errors are completely avoided by a faulty movement of optical elements.
  • the radial lens assembly according to the invention is ideal for mass production.
  • the hardware usage for optics and sensors is significantly reduced.
  • the radial objective arrangement according to the invention is particularly suitable for use in the technical fields of motion detection, motion detection, image recognition and light intensity determination as well as in the field of data communication.

  • the radial lens assembly is good for both daytime use and night use.
  • the radial lens arrangement is preferably formed by a self-supporting construction, which preferably requires no calibration or adjustment prior to use. Rather, the radial lens assembly is ready for use after their production readily available. This results in particular from the use of the monolithic piece of material.
  • a respective one of the plurality of optical rings preferably comprises an inner circumferential surface facing in a direction opposite to the radial direction.
  • the central light deflection unit is preferably designed to decouple the light coming from the detection area via the respective inner jacket surface and to forward it to the light collecting unit.

Rather, the radial lens assembly preferably comprises only a single component, namely said monolithic piece of material, in which the light collecting unit and the Lichtumlenkmaschine are formed.
  • the 'number' of optical rings which - as I said - can also be one, results from the design of the outer and / or inner lateral surfaces. In this case, depending on the desired detection range, different angles of curvature or taper angle and / or curvature can be selected (which will be explained in more detail later), so that virtually a plurality of optical rings is formed.
  • the central light deflection unit is preferably designed to break the light coming from the detection area in such a way that a light transport in the beam path, that is to say when the observation surface passes through, has a parallel course. Furthermore, the central light deflection unit is preferably designed such that light is scattered and / or attenuated outside the parallel course on an upper and / or a lower jacket surface of the central light collecting unit. This scattered and / or dim light loses itself in the noise. With this approach, the refraction of light and the light transport are bound to simple calculation algorithms.
  • the number of optical rings are preferably designed to provide a light transport in a parallel beam path and / or in a focused light transport with total reflection.
  • the number of optical rings each have a shape of a hollow cylinder, wherein the outer radius of the respective hollow cylinder is preferably a multiple of the height.
  • the inner radius of the respective hollow cylinder is a multiple of the height.

  • the light collection unit of the radial lens assembly is configured as an optical cone or cylinder, wherein a base of the cone or the cylinder forms the observation surface on which the forwarded light is projected by the light collection unit.
  • the light collected by the light collecting unit thus preferably falls perpendicular to the observation surface. From there, it can be directed, for example, onto a photoresistive surface, which is preferably connected to an evaluation unit, such as a camera module.
  • the center angle of the optical cone is constant, for example, and is 45 degrees, for example.
  • at least part of the conical surface in one embodiment of the radial objective arrangement is, for example, concave and / or convex and / or lenticular.

  • the bevel angle By selecting the bevel angle, it can be defined which detection range is to be picked up by the radial lens arrangement.

With such a determination, an observation height and a distance of the objects are fixed, i. the determination of the focal points for sharpening. If the central light deflection unit comprises not only one optical ring but several, then the bevel angles can be chosen to be different from one another, so that the incident light is always forwarded to the light collection unit. Several optical rings define different observation areas of the detection area. The light collecting unit then projects the relayed light onto the observation surface.
