| 摘 要： | 针对图像型火灾探测技术中的定位问题,提出一种在摄像机内外参数未知的条件下解决火灾二维定位的方法。即首先根据定标板角点的世界坐标和图像坐标计算透视投影矩阵,并在采用图像处理技术获取火灾图像的中心坐标的基础之上,通过求解线性系统获取火灾的实际位置。

| Abstract: | To solve the location problem in fire detection technology based on image, a fire 2-D location method is proposed, which does not require computation inside and outside parameters of camera, namely, fire is detected and the center coordination of fire im-age is acquired firstly by image processing technology, then perspective projection matrix is computed using world coordinates and im-age coordinates of calibration board corners, lastly the real position of fire can be computed by means of solving linear system. |
