The invention discloses a method and device for determining a temperature drift correction curve equation, equipment and a storage medium, and belongs to the technical field of thermal imaging. Comprising the following steps: acquiring j first cavity temperatures and j first gray values in one-to-one correspondence with the j first cavity temperatures; according to the j first cavity temperatures and the j first gray values, acquiring a temperature drift correction curvilinear equation of the first equipment as a reference curvilinear equation; when the external environment temperature is a preset temperature, obtaining a second cavity temperature and a second gray value corresponding to the second cavity temperature to obtain k second cavity temperatures and k second gray values; and according to the k second cavity temperatures and the k second gray values, adjusting the reference curvilinear equation to obtain a temperature drift correction curvilinear equation of the second equipment. According to the method, the determination efficiency of the temperature drift correction curve equation of the second equipment is improved, processing resources and determination time are saved, so that the production time of a plurality of thermal imaging equipment can be saved, and the production efficiency is improved.
Description
technical field [0001] The present application relates to the technical field of thermal imaging, in particular to a method, device, equipment and storage medium for determining a temperature drift correction curve equation. Background technique [0002] After the thermal imaging device starts to work, as the temperature of the external environment increases, the temperature inside the cavity (that is, the cavity temperature) will increase accordingly. Once the cavity temperature of the thermal imaging device rises, the temperature of the object detected by the thermal imaging device will drift, that is, a temperature drift phenomenon will occur, resulting in inaccurate temperature detection of the object. The drift phenomenon is corrected. [0003] In the related art, technicians place each of the multiple thermal imaging devices in an incubator during production, and then gradually adjust the temperature of the incubator. Varies with temperature changes. Each thermal im...
