Temperature measurement correction method based on thermal image and thermal image device

The invention discloses a thermal image-based temperature measurement correction method and a thermal image device. The temperature measurement correction method comprises a shooting stage, a processing stage and a correction stage. In the shooting phase, the thermal image camera shoots the monitoring environment to generate a measurement thermal image. In the processing stage, the processor executes operation according to the measurement thermal image to obtain target information, the target information corresponds to a measurement target in the monitoring environment, and the target information comprises a target image block and a target measurement temperature corresponding to the target image block. In the correction stage, the processor obtains a distance compensation value according to the number of pixels of the target image block, and performs correction operation on the target measurement temperature at least according to the distance compensation value to generate a correction temperature value corr
