Abstract
Systems and methods of detecting a vortex made by a travelling object is disclosed. Techniques include positioning a media collector to capture a visual media file of the vortex. In some configurations, a graphic recognition algorithm and vortex similarity engine are used to determine whether a visual media file captured by a media collector contains a vortex. In some configurations, a computer may trigger an alert if a travelling object vortex is not expected to be in the visual media file.
Claims25
A system comprising:
- a media file analyzer configured to analyze visual media files of travelling object vortices and non-travelling object vortices;
- a vortex similarity engine comprising:
- a graphic recognition algorithm configured to generate graphic elements from the visual media files;
- an element profile generator configured to:
- identify an element in common amongst the visual media files;
- and
- generate an element similarity profile by:
- identifying a graphic property that some of the travelling object vortex visual media files share;
- identifying a graphic property that some of the non-travelling object vortex visual media files share;
- identifying a graphic property that some of the visual media files do not share;
- identifying a graphic property that some of the non-travelling object visual media files do not share;
- said vortex similarity engine configured to:
- receive an unclassified visual media file;
- compare the unclassified visual media file with the element similarity profile;
- determine a travelling object vortex similarity ratio to indicate whether the visual media files depict a travelling object vortex;
- a visual media file classifier configured to classify the visual media files as a travelling object vortex or not travelling object vortex based on the travelling object vortex similarity ratio of the visual media file;
- and
- an alert generator configured to generate an alert if the visual media file classifier determines the received unclassified visual media files contain a travelling object vortex.

- a probability calculator configured to determine an overall travelling object vortex probability based on an aggregation of the vortex similarity ratios;
- the overall travelling object vortex probability being a measurement of a probability that the first, second, and third visual media depict a travelling object vortex;
- and
- an alert trigger configured to trigger an alert if the overall travelling object vortex probability exceeds a predetermined threshold.

A method comprising the steps of:
- positioning a media collector to face a ground surface from an elevated position;
- the media collector facing a region of air above the ground surface;
- capturing one or more images or videos of the region above the ground surface;
- receiving the images or videos with a computer;

- triggering an alarm if the travelling object is not on a registered flight plan;
- and
- logging the flight into a flight plan as a validated flight if the travelling object is on a registered flight plan.
