Based on the principle of stereo vision and vertical intersection of measurements to locate the fire and filter locator data of the CCD sensor using probability, the locating data accuracy was improved to serve the fire safety of large space building. By comparing experimental simulation and traditional fire location way, it was showed that this method mentioned in the article is more accurate and reliable, and will be widely applied in the field of fire allocation.%以立体视觉原理为基础,采用垂直交汇CCD视觉测量方法对火灾进行定位,并对定位数据进行概率滤波,使定位数据的精确性更好地适用于高大空间建筑消防安全的需要.通过实验仿真并与传统的消防炮定位方式进行比较,表明该方法具备较好的精确性与可靠性,在火灾定位上有着良好的应用前景.
