The spatial orientation of fire ignition can support an automatic fire suppression system (AFSS). However, due to the ambiguity of 2D images, most of the existing methods tend to study fire detection and cannot carry out spatial orientation. To solve this problem, we propose a spatial orientation method of indoor fire ignition based on monocular vision and virtual scenes. First, a hierarchical virtual scene construction method is proposed to realize the rapid construction of indoor scenes. Second, the characteristics of the fire are analyzed to obtain fire ignition in a 2D image. Finally, the spatial orientation of indoor fire ignition is calculated by analyzing the characteristics of fire attachment and the principle of three-dimensional imaging. The experimental results show that the absolute error of the spatial orientation of our method is 10.27 cm, and the relative error is 4.08%, which can meet the needs of AFSS.
