摘　　要：为了及时对火源定位,提出了一种多视点火源定位算法框架。该框架融合了多个摄像机的单视点火焰检测结果。每个摄像机的检测结果通过单应变换投射到多个虚拟的水平和垂直平面,这些平面将整个监控场景进行了划分,形成了一个三维虚拟网格。利用这个网格可以获得火源的空间位置信息。实验结果表明,所提出的多视点火源定位算法能够有效地定位火源,使用两个摄像机就可以得到较高的定位精度,增加摄像机的数量可以进一步提高定位精度。In order to locate the fire in time,a multi view fire location method is proposed,which integrates the single-view fire detection results of multiple cameras.The detection results of each camera are mapped to multiple virtual horizontal and vertical planes through homographic projection,which divide the entire monitoring scene into a three-dimensional virtual grid.The location information of fire can be obtained by using this grid.The experimental results showed that the proposed multi-view localization method can effectively localize the fire.Using two cameras can get higher positioning accuracy, and the positioning accuracy can further be improved by increasing the number of cameras.
