Real-time video fire flame and smoke detection method based on foreground image accumulation and optical flow technique is presented. Accumulation images are calculated of the foreground images which are extracted using frame differential method. Two parameters are used for the foreground image accumulation to differentiate flame candidate areas from that of smoke. The flame regions are recognized by a statistical model build by foreground accumulation image, while the optical flow is calculated and a motion feature discriminating model to recognize smoke regions is used. The algorithm could realize the real-time fire detection of the following three detection cases: fire with flame and none smoke, fire with smoke and none flame, and fire with both flame and smoke. © 2013 International Association for Fire Safety Science.

Due to the fast development of petrochemical industrial park in our country, increasing of large-scale petrochemical industry production device and storage device, continuous increasing quantity of major danger source and more likely occurrence of major and extra serious accidents such as fire and explosion, this article puts forward the key issues for petrochemical industrial park fire planning by combing with the current status of fire planning for petrochemical industrial park in our country, hoping to provide references and suggestions for preparing petrochemical industrial park fire planning in future. © (2013) Trans Tech Publications, Switzerland.
