Forest-Fire Response System Using Deep-Learning-Based Approaches With CCTV Images and Weather Data

Abstract

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, a large-scale fire dataset with approximately 400,000 images is used to train and test object-detection models. The optimal backbone for the faster region-based convolutional neural network (Faster R-CNN) model is determined using a DetNAS-based architecture search algorithm. Then, the searched light-weight backbone is compared with well-known backbones, such as ResNet, VoVNet, and FBNetV3. In addition, 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 Bayesian neural network (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.

A Forest Fire Recognition Method Based on Modified Deep CNN Model

“…A study used a deep CNN for recognition and achieved improved accuracy compared with that of traditional methods; however, identifying the entire video input required considerable time in practical applications [36]. A study used an SVM classifier to identify flames; however, different features need to be selected as inputs to the classifier, and the selected features are subjective and cannot be guaranteed to be the best features [37].…”

Deep Learning-Based Pose Estimation for Identifying Potential Fall Hazards of Construction Worker

“…Recent advancements in technology are poised to significantly transform the paradigm of worker safety through the automation of risk assessments. Noteworthy progress has been achieved in the application of computer vision to identify potential hazards (Tran, et al, 2022). However, some studies exhibit limitations in their scope, especially regarding the precise localization of dangers and the evaluation of workers' proximity to such hazards.…”

Identifying Hazards in Construction Sites Using Deep Learning-Based Multimodal with CCTV Data

“…In construction sites, object detection can identify critical elements such as workers, machinery, tools, and other potential hazards, thereby playing a vital role in safety monitoring. However, traditional object detection models typically operate independently, failing to incorporate the broader context of a scene (Jeon et al, 2023;Tran et al, 2022). These models often struggle with complex environments like construction sites, where multiple objects interact dynamically, and understanding these interactions is crucial for effective hazard detection.…”
