Definitions

  • the present invention relates to a pest detector for usage in various fields, such as agriculture, for instance in greenhouses, or food and grain storage.
  • catch plates equipped with sticky surfaces are applied.
  • the catch plates are typically set up in a matrix like structure, such that the density is one catch plate per, for example, 20 m2 of productive greenhouse area.
  • the catch plates are to some degree covered with pests and are currently inspected by means of magnifying glasses and/or microscopes, in order to determine which kind of pests have been gathered and in order to estimate their quantity.
  • the images must be of high resolution and of sufficient clarity to allow correct identification of, for instance, the subspecies of pests caught on the catch surface, potentially calling for specific pest treatment. This practically necessitates segmenting the catch surface 3 and taking for instance 50 segment images per catch surface, such that the entire surface can be captured in high resolution, in close proximity of the captured pests, yielding highest possible, warp-free image resolution (pixels per area).
  • the camera could be traversed over a flat catch plate surface, for instance by the use of two motors, one traversing in each direction of the plane wherein the catch plate lies.
  • the present solution resolves this situation such that only a single motor 12 must be applied to record images of essentially the entire surface.
  • the image capturing process may begin with the catch surface set to its lowest position (FIG. 1).
  • the catch surface is turned step-wise, each step corresponding to the width captured by the camera.
  • the steepness of the thread is determined by the fact that after one turn, the camera should depict essentially a hitherto uncovered area above the area covered by the camera one turn previous.
  • the image capturing Upon the catch surface reaching its maximal vertical position, the image capturing is completed.
  • the number of captured images, and therefore the number of steps, directly relates to the desired image resolution (pixels per area).
  • the detection unit connects to a local wifi network and uploads the images and other relevant information to a computer hosting or in connection with a neural network trained specifically to detect pests and/or other objects of interests, for instance, but not limited to, thrips, whiteflies or pollen particles.
  • a software program can be constructed to, via a graphical user interface, produce heat maps of the pest density. This would produce an easily accessible visual indication of state-at- hand to the controller.
  • FIG. 1 shows, from an upper view, an embodiment of the detector 1 with attached camera 2, in its collapsed state, where the rotating central body and the catch surface is lowered as much as possible.
  • the current rotational position of the catch surface 3 can be inferred from the position of the marker 4.
  • FIG. 2 shows, from an upper view, an embodiment of the detector with attached camera, in its extended state, where the rotating central body and the catch surface is elevated as much as possible.
  • the thread 5 on the stationary central body 9 is here clearly visible.
  • FIG. 3 shows, from a low view, an embodiment of the detector with attached camera, in its collapsed state, where the rotating central body and the catch surface is lowered as much as possible.
  • the slide groove in the stationary central body 6 is visible, as is the sliding assembly 7. Also depicted is the supporting surface 14 of the detector.
  • FIG. 4 shows, from a low view, an embodiment of the detector with attached camera, in its extended state, where the rotating central body and the catch surface is elevated as much as possible.
  • the slide groove in the stationary central body 6 is here clearly visible.
  • FIG. 5 shows, from an upper view, an embodiment of the detector with attached camera, in its collapsed state, where the rotating central body and the catch surface is lowered as much as possible and where the indicated cone 8 represents the volume covered by the view angles of the camera, roughly indicating the area of the catch surface covered by the camera in the current position. Notably, the camera in this position covers an extreme high area of the catch surface.
  • FIG. 6 shows, from a low view, an embodiment of the detector with attached camera, in its extended state, where the rotating central body and the catch surface is elevated as much as possible and where the indicated cone 8 represents the volume covered by the view angles of the camera, roughly indicating the area of the catch surface covered by the camera in the current position. Notably, the camera in this position covers an extreme low area of the catch surface.
  • FIG. 7 shows an exploded view of an embodiment of the detector from a top view, showing the key components: a stationary central body 9 equipped with a slide groove 6, a thread 5 and being connected to a radially positioned inward facing camera 2, a rotating central body 10, a central sliding body 11, a motor 12 having an output shaft 13, and a catch surface 3.
  • FIG. 8 shows an exploded view of an embodiment of the detector from a low view, revealing the key components: a stationary central body 9 equipped with a slide groove 6, a thread 5 and being connected to a radially positioned inward facing camera 2, a rotating central body 10 equipped with a thread 15, a central sliding body 11, a motor 12 having an output shaft 13, and a catch surface 3.
  • FIG. 9 shows a cut through an embodiment of the detector, revealing the key components: a stationary central body 9 equipped with a slide groove 6, a thread 5 and being connected to a radially positioned inward facing camera 2, a rotating central body 10 where the catch surface 3 is positioned in the lowest possible position, also showing the motor 12 and output shaft 13, here connected to the rotating central body, a central sliding body 11, here fastened to the motor.
  • FIG. 10 shows the same embodiment as shown in FIG. 11, albeit in the state where the catch surface 3 is positioned in the highest possible position.
  • FIG. 11 shows an alternative embodiment 16 where a sliding axle 14 connected to the axle of the motor is visible, in a top view with collapsed detector
  • FIG. 12 shows the same alternative embodiment in a low view where the detector is maximally extended.

  • FIG. 1 shows the compactness that this embodiment can achieve in its collapsed form, where FIG. 2 shows the maximal vertical dimension of the embodiment.
  • the threads are shown in the figures to be external to the stationary central body and internal to the rotating central body. In alternative embodiments, the thread on the stationary central body could be internal and the thread on the rotating central body could be external.
  • the invention however embodied, provides a detection unit for detecting pests, for instance thrips or whiteflies by relatively simple mechanical means, applying a threaded rotating and extending mechanism ensuring the best possible image resolution for the least possible financial expenditure.
  • the invention has the additional advantage that the exterior dimensions of the detector can be kept small. This allows the detector to not consume more space than a regular pot plant, making placement of the detector unproblematic for greenhouse workers.
