| Abstract(in English) | Knowing the three-dimensional spatial distribution of the smoke such as smoke, fog, and fire, are useful. However, method to estimate spatial distribution of the the smoke is not established yet. This paper describes a method for spatial distribution using a light field camera that can generate the image with arbitrary focal points. A number of images are reconstructed as varying the focal point from the scene image including the smoke. The planar density at the depth corresponding to the focal point is estimated from the reconstructed image. Then, the spatial density distribution of the object is estimated with a composition of the estimated density planes. This report shows the reconstructed spatial distribution from simulated smokes. |
