Fire passage occupation visual inspection method and system

Abstract

The application discloses a fire passage occupation visual inspection method and system, and belongs to the field of computer vision monitoring and fire safety management. In order to solve the problems of lagging behind in manual inspection, and misjudgment caused by personnel, light and background sundries, the application separates personnel and non-personnel foreground from a multi-light background prototype subjected to closed-loop gating, and confirms the continuous occupation residual after the personnel exit by bidirectional time sequence recovery. The same residual is mapped to a passage graph and an identification line-of-sight graph, and events and evidence are output according to the connected state, the bottleneck remaining net width and the continuous visible proportion, so that continuous inspection of the passage and the evacuation identification line-of-sight function of the fire passage is realized.
