Abstract: This paper focuses on the real-time and effectiveness issue of fire control system which is based on video in large space building, then proposes a camera self-calibration of the adaptive differential evolution algorithm which is based on improvement. It gets the exact matching points by using a fused method SURF fire image feature point matching algorithm that combined with ratio method and correlation function method. It processes the camera self-calibration, uses relatively accurate matching points to obtain basic matrix F, it gets the optimization function according to the property of absolute conic. It optimizes the function based on improved differential evolution algorithm, obtains the camera intrinsic parameters and gets the three-dimensional information of the fire source. Experimental results show that this method can get the relatively accurate three dimensional information about the fire source in a short period of time, in addition, the real-time and accuracy can meet the standard of the fire control system to put out the fire effectively.
