Suburban Forest Fire Risk Assessment and Forest Surveillance Using 360-Degree Cameras and a Multiscale Deformable Transformer

Abstract

In the current context of climate change and demographic expansion, one of the phenomena that humanity faces are the suburban wildfires. To prevent the occurrence of suburban forest fires, fire risk assessment and early fire detection approaches need to be applied. Forest fire risk mapping depends on various factors and contributes to the identification and monitoring of vulnerable zones where risk factors are most severe. Therefore, watchtowers, sensors, and base stations of autonomous unmanned aerial vehicles need to be placed carefully in order to ensure adequate visibility or battery autonomy. In this study, fire risk assessment of an urban forest was performed and the recently introduced 360-degree data were used for early fire detection. Furthermore, a single-step approach that integrates a multiscale vision transformer was introduced for accurate fire detection. The study area includes the suburban pine forest of Thessaloniki city (Greece) named Seich Sou, which is prone to wildfires. For the evaluation of the performance of the proposed workflow, real and synthetic 360-degree images were used. Experimental results demonstrate the great potential of the proposed system, which achieved an F-score for real fire event detection rate equal to 91.6%. This indicates that the proposed method could significantly contribute to the monitoring, protection, and early fire detection of the suburban forest of Thessaloniki.

AgriFireInfo v1.0: An Open-Source Platform for the Monitoring and Management of Open-Field Crop Residue Burning

“…In order to protect the environment and residents' health, numerous countries have implemented a series of policies and adopted heterogenous control measures to mitigate fire events [8,9]. These control measures primarily include traditional regular patrols [10,11], the installation of advanced electronic monitoring equipment [12], the utilization of unmanned aerial vehicles [13,14], and the establishment of watchtowers [15]. However, the above methods have inherent limitations, i.e., they are time-consuming and labor-intensive.…”

“…Not only in Brazil but also in different regions of the world, new research and fire risk models have been widely tested and used in an attempt to reduce the threat to life and ecosystems in these regions, such as the studies conducted in India [14], Greece [15], and China [16].…”

Accuracy Assessment of Drone Real-Time Open Burning Imagery Detection for Early Wildfire Surveillance

“…Unfortunately, these sensors may work efficiently in a closed environment but are unsuitable in forests because they are less effective in close proximity to fire and smoke. Similarly, on-ground thermal cameras mounted on a watchtower are expensive [9].…”

“…Unfortunately, these sensors may work efficiently in a closed environment but are unsuitable in forests because they are less effective in close proximity to fire and smoke.

An autonomous unmanned aerial vehicle (UAV)-based wildfire detection and surveillance system is a solution for remote sensing technologies [10,11].…”
