摘　　要：通常采用双目视觉技术实现对明火的空间定位,其中摄像机标定是双目视觉定位技术中的关键问题。基于线性模型,设计了自寻的消防水炮对明火自动检测与定位过程中的摄像机标定算法,实现了从世界坐标系到像素坐标系的转换,为控制消防水炮动作提供参数。实际测试表明,该方法计算速度快,精度高,具有较高的工程应用价值。Abstract：The calibration of camera is a key issue of the technol- ogy of binocular vision, which is usually used to achieve the spatial position of fire. An algorithm of the calibration of cam- era in the process of automatic detection and location of fire by fire monitor was designed based on linear model. It realized theconversion from the world coordinate nate system and provided parameters system to the pix for the control act monitor. Actual tests showed that this method has fast speedand high precision, with a higher value in engineering.
