Title Research of The Automatic Generation Algorithm and Application of 2D Fire-Forbidden Map
Abstract
Setting the fire-forbidden area artificially, a traditional method, exists many shortcomings, such as long calibration time, low accuracy, uneasy carried equipment and so on. In this paper, an automatic method for generating 2D fire-forbidden map is proposed, with the understanding of the principle of 2D fire-forbidden map. Due to powerful computing and graphics expression functions of MATLAB, we use it to generate random 3D digital terrain map and design corresponding algorithm to create the fire-forbidden map. Then considering the actual situation, using Google map toolbox to generate the geography information of the appointed area, and importing the information into MATLAB. According to the information, Generating the corresponding 3D digital terrain map and 2D fire-forbidden map with the former proposed method. Drawing relevant conclusions on the basis of the analysis to the simulation results.
