Abstract: A thermal image-based temperature measurement calibration method applicable to a thermal image device is provided. The method includes a capturing stage, a processing stage and a calibration stage. During the capturing stage, the thermal image device captures a monitored environment to obtain a measured thermal image. During the processing stage, a processor processes on the measured thermal image to obtain a target information, wherein the target information corresponds to a target in the monitored environment, and the target information includes a target image block and a target measured temperature corresponding to the target image block. During the calibration stage, the processor obtains a distance compensation value according to a pixel number of the target image block, and the processor performs a calibration operation to the target measured temperature at least according to the distance compensation value to obtain a calibrated temperature value corresponding to the target.
