Abstract

The invention relates to an environment temperature acquisition method and system based on an internal temperature sensor of infrared temperature measurement equipment. The method comprises the following steps that the infrared temperature measurement equipment which is placed in a first environment for a preset time and is always in a shutdown state is moved to a second environment; within the working time after startup, a temperature sensor in the infrared temperature measurement equipment outputs internal temperature information of the equipment; internal temperature variation corresponding to each moment is acquired, and an environment temperature data set including the second environment temperature, the equipment internal temperature information and the internal temperature variation is constructed; and performing model training based on the environment temperature data set, and outputting an environment temperature prediction model. According to the invention, the internal temperature of the device is obtained through the temperature sensor in the infrared temperature measurement device, the predicted environment temperature is directly output based on the environment temperature prediction model, and the predicted environment temperature is directly used as the real environment temperature for subsequent temperature measurement result compensation, so that the temperature measurement precision of the infrared temperature measurement device under the environment temperature sudden change condition is greatly improved.
