Method, device and equipment for detecting maximum and minimum temperature region based on thermal imaging image

Abstract

The invention relates to the field of image processing, and discloses an extreme-value temperature region detection method, device and equipment based on a thermal imaging image, and the method comprises the steps: obtaining a thermal imaging video stream in a target time period according to a demand, and the thermal imaging video stream comprises a temperature legend; performing frame extraction on the thermal imaging video stream and storing the thermal imaging video stream as a thermal imaging image; identifying the highest temperature value and the lowest temperature value corresponding to the temperature legend in the thermal imaging image; extracting a highest temperature pixel value corresponding to the highest temperature value, and extracting a lowest temperature pixel value corresponding to the lowest temperature value; and according to the highest temperature pixel value, comparing and marking a highest temperature region in the thermal imaging image, and according to the lowest temperature pixel value, comparing and marking a highest low temperature region in the thermal imaging image. According to the method, the problem that the region where the extreme temperature is located is difficult to locate under the condition of only depending on the thermal imaging video stream and passive data is solved.
