This paper presents a new approach for the estimation of fire front volume in indoor laboratory experiments. This work
deals with fire spreading on inclinable tables. The method is based on the use of two synchronized stereovision systems
positioned respectively in a back position and in a front position of the fire propagation direction. The two vision
systems are used in order to extract complementary 3D fire points. The obtained data are projected in a same reference
frame and used to build a global form of the fire front. An inter-systems calibration procedure is presented and permits
the computation of the projection matrix in order to project all the data to a unique reference frame. From the obtained
3D fire points, a three dimensional surface rendering is performed and the fire volume is estimated.
