 4. Prediction of 3D position of pests by modelling their flight
    pattern

Prediction of 3D position of pests by modelling their flight pattern

- Contributes to technological development for pest extermination by
high-power lasers -

National Agriculture and Food Research Organization (NARO) has
developed a method to predict the pest flight position. This method
can detect the three-dimensional position of flying pests from the
image captured by the camera and predicts its movement. It is
expected that this research result will contribute to the development
of a new pest control system to exterminate pests, such as
irradiating a high-power laser at the predicted position.

Overview

NARO has succeeded in predicting the pest flight position by fusing
the modeled flight pattern of the pest with the three-dimensional
position calculated from the image captured by the stereo camera.

Efficient extermination of pests flying quickly in the air is not
possible with existing pest control technologies. As an epoch-making
physical method, technological development to exterminate pests with
high-power lasers etc. is in progress. In order to achieve this, it
was necessary to spot the exact pest location and eliminate the time
lag from detection to extermination.

Therefore, we captured the flight activity of Spodoptera litura (a
type of moth), a typical agricultural pest, with a stereo camera. We
measured the three-dimensional position and investigated their flight
pattern. Then we modeled the obtained flight pattern and developed a
new method that can predict the position several steps ahead (0.03
seconds ahead) with an accuracy of about 1.4 cm from the real-time
image.

It is expected to break away from dependence on pesticides by means
of applying this method to technology for exterminating pests with
high-power lasers, etc. Thereby we can realize sustainable
agricultural production that can balance both pest control and
environmental conservation. We aim for the practical utilization of
the technology to exterminate pests by irradiating the predicted
position with a laser by the year 2025.
