Tunnel fire pool monitoring method and system based on combinatorial algorithm

The invention belongs to the field of tunnel pool monitoring, and particularly relates to a tunnel fire pool monitoring method and system based on a combinatorial algorithm. The tunnel fire pool monitoring method comprises the steps that S1, sensor data and a video sequence of a water body are obtained through the Internet of Things, and the sensor data at least comprise a liquid level value, a temperature value, an HP value, a water pressure value and a leakage value; s2, performing first threshold judgment on the sensor data to obtain water body characteristics; s3, obtaining a water body motion image according to the video sequence; s4, predicting a current accident scene according to the similarity between the water body motion image and the training image through a pre-established mapping library of the training image and the accident scene; and S5, performing regression calculation on the water body characteristics and the accident scene to obtain a prediction result.
