Abstract
Accurate forest fire location during the initial stages is vital for suppressing forest fires. However, in some mountainous areas, accurate automatic fire location is still a challenging task. There is a lack of a good association mechanism between video space and external geographic information. In this paper, we propose a method to measure the fire location and accurately map it to the stereo space coding, which uses the feedback parameters (yaw angle, pitch angle, geographic location and altitude where the camera installed) and digital elevation model. The position of the fire point from the image coordinate system is obtained by computer vision method, and then transform it to the camera coordinate system and the world coordinate system by coordinate transformation. And we establish the mapping from longitude, latitude and height coordinates into stereo grid code to achieve the construction of video stereo grid space. The proposed method has also been deployed and verified in actual forest video monitoring system.
