Obstacle-Aware Rescue Routing on Construction Site Based on BIM and Computer Vision
Publication: ICCREM 2021
ABSTRACT
With the increasing complexity of building structure, the evacuation management on construction site is becoming difficult but essential. The existing onsite emergency response mostly adopts manual management for making evacuation plan and monitoring the objects affecting emergency evacuation. This paper proposes an obstacle-aware rescue routing framework for construction site based on BIM and computer vision. An updating framework is developed for maintaining the consistency of BIM model and onsite situation. Moreover, according to the demand of onsite rescue routing, the geometric and semantic information of on-site obstacles are determined and updated automatically, after which the obstacle-aware rescue routing is performed. The methodology is tested in a real case in construction site. Experiment shows that the generated rescue route is able to avoid obstacles and implement accurate navigation.
