Method and device for detecting high temperature heat source

The invention discloses a detection method of a high-temperature heat source, comprising that the incident radiation of a target to be detected is decomposed into the visible light spectrum radiation and the near-infrared spectrum radiation; images of the visible light spectrum radiation and the near-infrared spectrum radiation are collected; whether the high-temperature heat source is contained in the target to be detected or not is judged according to the collected images of the visible light spectrum radiation and the near-infrared spectrum radiation. The invention further discloses a detection device of the high-temperature heat source, comprising a beam splitting prism, a first back-and-white CCD sensor, a second back-and-white CCD sensor and a diagnostic unit of the high-temperatureheat source. The detection device can effectively detect the high-temperature heat source of the target to be detected when the radiation of the high-temperature heat source with the temperature range of 800K to 2000K is simi
