Problems solved by technology

The traditional road tunnel fire accident detection rate is slow, and the rate of missed and false alarms is high, which not only leads to the untimely acquisition of tunnel fire disaster information, which is not conducive to on-site decision-making and rescue, but also detects the life safety of firefighters. Fire smoke dynamic detection

Abstract

The invention relates to a highway tunnel fire smoke dynamic detection method, and belongs to the technical field of highway tunnels. The method comprises the following steps: S1, extracting a motion area; S2, segmenting a suspected smoke region; S3, feature analysis and extraction; and S4, fire smoke detection. According to the method, suspected smog area segmentation is carried out in a YUV color space through a color filtering rule based on a motion area extracted by a Gaussian mixture model, then color and texture features of smog in the suspected smog area are mainly researched, a color moment of the smog is calculated, a uniform local binary pattern (ULBP) and a gray level co-occurrence matrix (GLCM) of the smog are extracted to carry out feature fusion, a machine learning classifier is used for model training to distinguish smoke and non-smoke, smoke recognition is completed, and an optimal algorithm is selected according to an analysis result.

Description

technical field [0001] The invention belongs to the technical field of road tunnels and relates to a dynamic detection method for fire smoke in road tunnels. Background technique [0002] Under the special environment of closed road tunnels, fire has become the biggest threat to the safety of road tunnel operations. The traditional road tunnel fire accident detection rate is slow, and the rate of missed and false alarms is high, which not only leads to the untimely acquisition of tunnel fire disaster information, which is not conducive to on-site decision-making and rescue, but also detects the life safety of firefighters. Fire smoke dynamic detection. Based on the high-definition camera in the tunnel, the artificial intelligence algorithm is used to dynamically obtain the fire smoke in the tunnel, obtain the diffusion range and position of the fire smoke in the tunnel in real time, and make reasonable decision-making for fire accident rescue, which has important engineerin...
