Abstract:

In order to help fire investigators determine the location of the fire origin, improve the chain of evidence in accident investigations and identify the cause of the fire quickly and accurately, the researches on fire origin determination based on fire traces were reviewed in present paper. First, fire traces were classified, including burn marks, smoke marks, collapse marks and electrical wiring marks, with emphasis on soot deposition traces. Then, multiple fire origin determination methods at home and abroad were reviewed and classified into three categories: determining the fire origin directly using experience, determining the fire origin using numerical reconstruction techniques, and determining the fire origin using machine learning algorithms. The advantages and limitations of each method were analyzed respectively. Finally, the future research tendency of fire origin determination technology was prospected. The results show that numerical simulation of soot deposition traces combined with machine learning for fire origin determination has a good perspective for application.

Key words: fire origin, fire traces, numerical reconstruction, machine learning, soot deposition traces
