Abstract

Abstract: During the building fire emergency rescue, most of the paths generated are based on a single type of road network, and it is difficult to balance the accuracy of indoor global path planning and the speed of path finding. Therefore, a method of building an indoor integrated road network is proposed. The algorithm of generating topological road network and grid road network is implemented indoors, and the fusion algorithm and cross floor channel extraction are designed by ourselves to obtain a three-dimensional indoor road network. The path weight model is combined with the routing algorithm to find the optimal fire rescue path, and the quadratic path planning is designed. Finally, the method is used to extract the indoor road network of the experimental model and compared with the above two single road networks to verify the effectiveness of the road network extraction method.

Key words: fire rescue, generation of regional road network, integrated road network, path planning
