摘要: 以两起火灾事故调查为例,介绍了火灾现场三维建模在火灾视频光影分析中的应用。通过火场三维建模技术与几何作图法的结合,分析了一起民房火灾起火过程中火光光源位置的变化和火灾的蔓延过程。通过火场三维建模技术在光影分析中的独立应用,分析了一起客厅火灾中起火初期火光光源的位置。在此基础上,分析了火场三维建模技术在火灾视频光影分析中的优势和实践中应注意的事项,为火场三维建模在火灾视频光影分析中的应用提供了方法参考。

Abstract: Taking the investigation of two fire accidents as an example, this article introduces the application of 3D modeling of fire scenes in light and shadow analysis of fire video. By combining 3D modeling technology of the fire scene with geometric drawing method, the changes of the position of the firelight source and the spread of the fire during a residential fire were analyzed. Through the independent application of 3D modeling technology in light and shadow analysis, the position of the initial firelight source in a living room fire was analyzed. On this basis, the advantages and practical considerations of 3D modeling technology in light and shadow analysis of fire video were analyzed, providing a methodological reference for the application of 3D modeling in light and shadow analysis of fire video.

Key words: 3D modeling, visualization of fire scenes, fire video, light and shadow analysis, fire investigation
