Forest-Fire Response System Using Deep-Learning-Based Approaches With CCTV Images and
Weather Data
An effective forest-fire response is critical for minimizing the losses caused by forest fires. The purpose
of this study is to construct a model for early fire detection and damage area estimation for response
systems based on deep learning. First, we implement neural architecture search-based object detection
(DetNAS) for searching optimal backbone. Backbone networks play a crucial role in the application of deep
learning-based models, as they have a significant impact on the performance of the model. A large-scale fire
dataset with approximately 400,000 images is used to train and test object-detection models. Then, the
searched light-weight backbone is compared with well-known backbones, such as ResNet, VoVNet, and FBNetV3.
In addition, we propose damage area estimation method using Bayesian neural network (BNN), data pertaining
to six years of historical forest fire events are employed to estimate the damaged area. Subsequently, a
weather API is used to match the recorded events. A BNN model is used as a regression model to estimate the
damaged area. Additionally, the trained model is compared with other widely used regression models, such as
decision trees and neural networks. The Faster R-CNN with a searched backbone achieves a mean average
precision of 27.9 on 40,000 testing images, outperforming existing backbones. Compared with other regression
models, the BNN estimates the damage area with less error and increased generalization. Thus, both proposed
models demonstrate their robustness and suitability for implementation in real-world systems.
