Real-time animal detection and prevention system for crop fields
KDU International Research Conference 2020(2020)
摘要
Every year, crop damaged by wild animals is
dramatically increasing in Sri Lanka. It often poses risks to
humans and animals. Since more and more wild animals
are causing damage to their cultivation; humans could not
tolerate it. Therefore, they require an effective mechanism
to overcome this situation. With that background, the
objective of this study is to detect wild animals before
entering into the crop fields and implementing appropriate
scare-away mechanisms in real-time. The presence of the
animal will be sent to the farmer via a mobile application.
In this study, two Convolutional Neural Network (CNN)
classification models have been developed using the
transfer learning approach with the VGG-16 as a pre-trained model to detect elephants, wild boars, and buffalos.
Both two models were combined and runs on Raspberry pi,
which acts as the processing unit for the system, captures
the images of animals, and predicts it. Whenever the
presence of the animal senses by the thermal sensor which
is installed on Arduino, it sends a trigger to capture the
image. Based on the prediction sudden flashes of light,
ultrasound, and bee sound will be produced to scare away
the animals. The mobile application was developed using
react native which is used to alert the user about the animal,
connected through the Firebase database. The findings of
this research indicate that the accuracy rate of the
classification model is 77 percentage. This system
significantly reduces human-animal conflict in crop fields
by automatically implementing scare-away mechanisms
based on the prediction.
