This paper presents the indoor localization and navigation guidance scheme for fire evacuation system of the high and large buildings. Localization and navigation are very essential problems in indoor environments especially for fire evacuation system. Quick Response (QR) codes which its labels and location information that are read by camera acted as landmarks to provide global position references in unknown environment relatively with floor plan of the static routing localization of fire exit paths. For dynamic routing localization, Radio Frequency Identification (RFID) traffic cones were used as alternative landmarks to provide the local position references and up to date navigate. These RFID tags were installed in multi-RFID traffic cones in any way of fire exit paths. It provides an efficiency real time management scheme with correct data reporting for fire evacuation occurred even if the main electricity is turn off. The data based was constructed and updated for supporting to each of RFID tags and QR codes of each fire evacuation path facilities and can be mapping their localizing into the floor plan of the fire building automatically. Fire exit signs and QR codes are classified in vision-based method that composed of an appropriate shape coding algorithm with back propagation neural network which multi-hidden layers to provide the correct signs that are meaningfully decided for suitable fire evacuation paths among available paths. The suitable fire exit path when fire explosion occurred is the main importance key not only for an efficiency of fire protection system management, but can be control the congestion situations, shortest evacuation time and safe for more life of all victims. Dijkstra’s algorithm and the shadowing method are applied in indoor fire exit path planning based on a two dimensions (2D) grid map, which the shortest path of all available fire evacuation paths was the first basically main criteria evaluation and second purposed performed for the real fire evacuation situation in this selective path that can be guarantee less congestion, more safety and available fire exit paths all time. Finally, experimental results were shown that this proposed technique has good feasibility and effectiveness enough to solve the indoor fire exit paths problems.
