Abstract

The invention provides a temperature measurement method and device, a server and a temperature measurement system. The method comprises the steps of detecting a target object from an environment imageobtained by image acquisition equipment, and determining a first position of the target object; obtaining a thermal imaging image corresponding to the environment image through thermal imaging equipment, and determining a thermal imaging temperature of the target object based on the first position; acquiring an environment temperature through temperature acquisition equipment; and adjusting the thermal imaging temperature of the target object according to the environment temperature and the thermal imaging temperature of the temperature acquisition equipment in the thermal imaging image to obtain the actual temperature of the target object. According to the method, the temperature drift of the thermal imaging equipment is corrected through the environment temperature and the thermal imaging temperature of the temperature acquisition equipment, and the accurate actual temperature of the target object can be obtained based on the thermal imaging temperature of the target object. In addition, the method employs the temperature acquisition equipment to replace a conventional black body so as to avoid defects of the black body, so that the method improves the robustness and reduces thedeployment difficulty while guaranteeing the temperature measurement precision.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a temperature measuring method, device, server and temperature measuring system. Background technique [0002] In related technologies, the non-contact temperature measurement method usually uses a blackbody-assisted thermal imaging device for temperature measurement. The thermal imaging device collects light in the thermal infrared band emitted by the target object in the environment, so as to detect the thermal radiation emitted by the target object. Then the thermal radiation is converted into a gray value, and the function curve between the gray value and the temperature is obtained through the calibration of the black body radiation source, and the corresponding relationship between the gray value and the temperature is determined based on the function curve. Based on this, when the target object is obtained After obtaining the corresponding gray value, the temperatu...
