An understanding of the spatial information for safety-related architectural features inside a school building is crucial for effective responses to emergency situations such as active shooter or fire incidences. However, efficiently creating high-quality spatial inventory for a wide variety of safety-related assets inside a large school building is a challenge for building owners.
From a paper by C. Di et al.
This study addresses this challenge by developing an AI-based approach for rapid generation of spatial inventory of safety-related architectural features within school buildings from point cloud data. A method for creating cross-modality data from laser scans is proposed to not only address the limitations in individual 2D and 3D datasets but also enable the transfer of the segmentation and generalization performance from the state-of-the-art Segment Anything model to point cloud segmentation. Additionally, our proposed method also demonstrates great potential to address the challenge of extracting glass façade frames from point cloud datasets.
Concerns regarding the safety and security of school buildings have intensified due to the escalating numbers of casualties and property damage resulting from both natural disasters and man-made incidents, including structure fires and active shooter events across various educational institutions in recent years (CHDS, 1970; Campbell, 2020; Balamurugan et al., 2019).
Given the vast and intricate nature of school buildings that serve as daily hubs for a significant number of occupants, it is insufficient to rely solely on security personnel for the building preparedness for emergencies. As a crucial complement, the safety- and security-related architectural features embedded in school environments play a pivotal role in enhancing overall safety and security, profoundly influencing the behavior of occupants (Abdirad et al., 2020). For example, occupants can activate alarm switches during emergencies, and the ensuing blare of alarm horns serves as a warning for others to initiate evacuation procedures.
Beyond the category of interactive safety devices, security-related features like metal detectors and surveillance cameras fall within the security-related category, exhibiting deterrent effects that may reduce the likelihood of malicious attacks (Zhu et al., 2020a). However, the influence of architectural features on human behavior can sometimes be complex, especially in instances where the scale and design of a school building, particularly those with a lot of glass facades, impact the indoor visibility.
