The invention discloses a temperature-sensitive camera temperature compensation method and system, and belongs to the technical field of temperature-sensitive cameras. Aiming at the problems of low precision and low measurement accuracy of a temperature-sensitive camera in the prior art, the invention provides the temperature compensation method and system for a temperature-sensitive camera. A temperature sensor is connected in front of the temperature-sensitive camera, and a black body is arranged, by calculating the functions of the temperature measured by the temperature-sensitive camera, the actual temperature of the temperature sensor, the black body temperature, the environment temperature and the measured entity distance, the influence brought by factors such as the drifting of thecamera, the non-uniformity of the temperature-sensitive camera, the refractive index of the temperature sensor, the environment temperature and the measured distance is calibrated. According to the invention, the temperature compensation of the temperature-sensitive camera is realized in a low-cost and high-precision manner, the corresponding calibration is real-time, the temperature-sensitive camera can be used all the time after leaving a factory and only needs to be calibrated once, a black body does not need to be arranged during measurement, the relatively high measurement precision is obtained in a low-cost manner, and the reliability is good.
