摘要
为了及时获取林火坐标,运用角度前方交会原理,以vb.net为开发语言,用supermap control可视化控件,实现了2台云台摄像机的林火定位。研究结果表明:运用角度前方交会原理可以克服1台云台摄像机不能对林火定位结果进行检验的缺点,2台云台摄像机可以分别计算林火坐标,并且相互检验。在此基础上,再求平均值,提高了林火定位精度。
In order to get the coordinates of forest fire timely, applying angular forward intersection, vb.net, supermap control, 2 PTZ （Pan/Tilt/Zoom） cameras, realized the function about the position of forest fire. The results showed that applying angular forward intersection can overcome the fault that 1 PTZ camera is unable to inspect the result about the position of forest fire, but 2 PTZ cameras can calculate respectively the coordinates of forest fire and inspect each other. On this basis, calculating average improved localization accuracy.
