| description | The invention relates to a gas cloud spectrum analysis method and device, and belongs to the technical field of gas detection. The method comprises the following steps: acquiring an infrared image of a to-be-measured target, converting the infrared image into a grayscale image, determining a temperature value of the to-be-measured target by using a relationship between an image grayscale value of the infrared image and temperature, acquiring radiation intensity data of an infrared detector, and obtaining the spectrum transmittance of the to-be-measured target according to the radiation intensity data and the temperature of the to-be-measured target. The column concentration of the gas is obtained according to the relation between the spectrum transmittance of the gas to be detected and the gas column concentration, and the leakage condition of the gas to be detected is analyzed according to the distribution condition of the column concentration of the gas. According to the method, the leakage information can |
