摘要

Data acquisition and reuse of dynamic flame provides a new way for realistic flame simulation. The virtual model has a comparable physical data support while reconstructing the realistic flame. In this paper, we focus on the acquisition and simulation of dynamic flame with temperature distribution. Firstly, a synthesis 2D dynamic flame texture method is proposed to simulate and edit the high frequency detail of dynamic flame based on temperature distribution. Secondly, a 3D flame reconstruction method is put forward to reconstruct and edit temperature field from the captured multi-view flame images based on pyrometry and fluid dynamics. The simulated flame has the constraints and support of the physical temperature data; and the dynamic flame can be edited based on the temperature distribution intuitively. Different flame scenes were tested and the experimental results show that our method is effective in flame temperature data acquisition and simulation.
