Problems solved by technology

The above-mentioned documents are all based on the detection model to detect two-dimensional images, and a large amount of sample data is needed to train the detection model. This process depends on the sample data. When the sample data is unbalanced, the detection model often falls into a local optimum, resulting in The extraction accuracy of the flame in the two-dimensional image is not high, and the flame area cannot be fully detected for the place where the edge of the flame is sparse, or the place covered by smoke, and the object with a similar color to the flame is easy to be misdetected. and less reliable

Abstract

The invention relates to a fire hazard identification method and system based on artificial intelligence and binocular vision. The method comprises the following steps: 1) obtaining a to-be-detected binocular image of a to-be-detected area; 2) using the target detection network model to determine whether flames exist in the binocular image to be detected, if yes, outputting a flame area image, and if not, executing the step 1); 3) performing three-dimensional space positioning on the flame area image to obtain three-dimensional information of the flame area image; 4) calculating the optimal field angle of the infrared temperature measurement sensor; 5) controlling the infrared temperature measurement sensor to measure the temperature of the flame area at the optimal field angle to obtain a temperature measurement value of the flame area; and 6) judging whether the temperature measurement value exceeds a set value, if so, judging that a fire occurs in the flame area, otherwise, judging that no fire occurs in the flame area, and executing the step 1). Compared with the prior art, the system is good in accuracy, high in reliability, high in safety, wide in application range and low in layout and maintenance cost, flame positioning is provided, and the fire extinguishing efficiency is improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence machine vision, in particular to a fire recognition method and system based on artificial intelligence and binocular vision. Background technique [0002] When a fire occurs, if it can be detected and called in time, the loss can be minimized. Existing fire detection methods mainly include sensor detection method and image detection method. [0003] The sensor detection method mainly uses sensors to monitor the temperature of the detection area, but the installation process and detection range of the sensors are restricted by space. When performing indoor detection, it is necessary to arrange sensors at multiple points and in a full range to ensure that no corner is missed, even in the flames. It can only be detected when a certain scale is formed. The monitoring is not timely, the layout is troublesome, the installation requirements are high, and the cost is high. When performing outdoor d...
