Smart mosquito trap for mosquito classification
An insect trap includes a combination of one or more components used to classify the insect according to a genus and species. The trap includes an imaging device, a digital microphone, and passive infrared sensors at the entrance of the trap to sense wing-beat frequencies and size of the insect (to identify entry of a mosquito). A lamb-skin membrane, filled with an insect attractant such as carbon dioxide mixed with gas air inside, mimics human skin so that the insect can rest on the membrane and even pierce the membrane as if a blood meal is available. An imaging device such as a passive infrared sensor or a camera gathers image data of the insect. The insect may be a mosquito.
1 . An apparatus to catch an insect and gather identifying data regarding the insect, the apparatus comprising:
a lamb-skin membrane body positioned within a membrane enclosure configured to mimic human skin and support the insect thereon, wherein the lamb-skin membrane body is fillable with a carbon dioxide gas attractant and porous to allow the carbon dioxide gas attractant to slowly leak out, the lamb-skin membrane body connected to a brass puck comprising a cartridge heater for heating the brass puck, wherein the brass puck is positioned in proximity to an inlet opening for directing the insect to perch on the lamb-skin membrane body and seek the carbon dioxide gas attractant disposed within the lamb-skin membrane body;
a plurality of imaging devices having respective fields of view that encompass the lamb-skin membrane body;
a microphone having a user-adjustable frequency range for increased or decreased sensitivity positioned within the apparatus and configured to obtain audio signals;
an active infrared sensor positioned at the inlet opening, wherein data obtained from the active infrared sensor is used to trigger the microphone to obtain the audio signals;
at least one sensor on an external surface of the apparatus configured to capture ambient environmental data including at least one of temperature, air pressure, altitude, humidity, latitude, longitude, time, CO 2 concentration and ambient light conditions; and
a processor operatively coupled to the plurality of imaging devices, the processor being operably connected to computerized memory storing computer-executable instructions which when executed by the processor, cause the processor to:
receive the audio signals from the microphone;
calculate a frequency signal corresponding to a wingbeat frequency of the insect;
responsive to determining that the wingbeat frequency is within a predetermined frequency range, trigger, via the active infrared sensor, the plurality of imaging devices to obtain images of the insect from a plurality of different angles,
determine a size of the insect based on a wing-beat frequency determined from the audio signals,
determine at least one anatomical component of the insect from the obtained images;
classify, using a machine learning classifier, the insect into a genus and species based, at least in part, on the determined size of the insect and the at least one determined anatomical component,
store insect data and the ambient environmental data in the computerized memory, and
responsive to detecting that the insect cannot be identified, generate an alert and transfer at least a portion of the stored data including the insect data and the ambient environmental data to a digital repository,
wherein the data is used to generate a set of training images for training one or more machine learning algorithms to identify the insect.
