The development of fire is often unpredictable, and the scale of fire spread is so large that fire rescue is difficult to grasp the whole site. This paper mainly predicts the area of fire spread based on the idea of DBSCAN algorithm, and simulates the spread trend of the disaster, with the image of open source scene. The particle system of OSG (Open Scene Graph) simulates the fire and its situation in three-dimensional scenes. Through the VS2017 and OSG development environment, the algorithm is simulated by the program to verify the practicability of the fire situation in the virtual simulation. This provides a feasible way to establish a realistic prediction of fire spread situation, and implements the fire suppression. The program provides a new reference.
