A Kind of Identification Method of Geometric Parameters for Forest Fire
Forest fire is a kind of natural disaster with devastating efTect on the ecological environment of the earth. In order to obtain the wildfire information in the fire scene in time and improve firefighters efficiency to suppress the fire, the digital information about the forest fire which can exactly depict the fire behavior is very important for the fire-figbting department to give a correct extinguishing decision. Here the concept of fire geometric parameters which include terrain inclination angle, flame inclination angle, flame point, flame height, flame base width, flame length and so on is put forward. At the same time a set of parameter identification approaches is proposed which includes contour extraction, feature point extraction and feature parameter calculation. Especially two novel extraction methods of the feature point of the fire image contour are discussed in detail and a kind of geometric parameter calculation method of the forest fire with a triangle contour is given.
