При решении задачи по обеспечению пожарной безопасности на крупных объектах промышленности важно обеспечить наивысшую скорость реагирования на возникающие угрозы. В данной работе рассматривается новый метод обнаружения и определения точного местоположения очага возгорания в реальном времени, основанный на современных методах обработки изображений и искусственного интеллекта.</p></sec><sec><title>Цели и задачи</title><p>Цели и задачи.

When solving the problem of ensuring fire safety at large industrial facilities, it is important to ensure the highest speed of response to emerging threats. This paper discusses a new method of detecting and determining the exact location of the fire centre in real time, based on modern methods of image processing and artificial intelligence.</p></sec><sec><title>Aims and Objectives</title><p>Aims and Objectives. The aim of the work is to create a system capable of detecting fire in a panoramic image and, based on a 3D model, determining the coordinates of the detected threat.</p></sec><sec><title>Objectives of the work</title><p>Objectives of the work:</p></sec><sec><title>Methods</title><p>Methods. The paper describes the scheme of the proposed system. Methods for detecting fires in the image are discussed. The choice of the approach using a convolutional neural network is justified. The application of a neural network in a panoramic image is considered and an approach to straightening distortions in the image is described in order to improve the accuracy of the network. A method for combining a 3D model with a panoramic image and determining the spatial coordinates of found fires is described.</p></sec><sec><title>Results and Discussion</title><p>Results and Discussion. The work shows the results of the system in a virtual environment where fires were generated. The environment emulates all key components of the system, such as a panoramic camera and a 3D model of the object. In the experiments carried out, the error in determining the coordinates of the fire was about 20 cm.</p></sec><sec><title>Conclusions</title><p>Conclusions. The work examined a new approach to detecting fires using computer vision. A neural network of the YOLOv5 architecture was trained, which is capable of recognizing fire and smoke. To reduce distortion, stereographic projection was used. A method was developed and applied to determine the coordinates of fire in space by combining a 3D model and a panoramic image.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>компьютерное зрение</kwd><kwd>обнаружение пожаров</kwd><kwd>обнаружение объектов в реальном времени</kwd><kwd>глубокое обучение</kwd><kwd>стереографическая проекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>computer vision</kwd><kwd>fire detection</kwd><kwd>real-time object detection</kwd><kwd>deep learning</kwd><kwd>stereographic projection</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zaman T., Hasan M., Ahmed S., Ashfaq S.
