ABSOLUTE TEMPERATURE MEASURABLE THERMAL IMAGE DEVICE FOR SEIZING A DISTRIBUTION OF AN ABSOLUTE TEMPERATURE IN A PRESENT TARGET

摘要

PURPOSE: An absolute temperature measurable thermal image device is provided not only to detect a relative temperature difference of each portion in a target but also to seize a distribution of an absolute temperature. CONSTITUTION: A first storing unit(241) stores a temperature table to show the relation between a temperature of a target and a temperature detection signal value of an infrared sensor(220) at an initial composition of an infrared camera. A temperature reference(250) discriminates the entire view angle of the infrared camera through a necessary absolute temperature. A basic temperature input unit(260) inputs the absolute temperature of the temperature reference to the infrared camera. A calculation unit(243) calculates a deviation between the temperature detection signal value corresponding to the input temperature of the basic temperature input unit in the first storing unit and an actual temperature detection signal value by receiving the temperature input of the reference temperature input and the actual temperature detection signal value photographed a thermal image of the temperature reference. The calculating unit obtains a new temperature table by compensating the deviation with each temperature detection signal value of the stored temperature table in the first storing unit. A second storing unit(242) stores the new temperature table obtained in the calculating unit for seizing a distribution of an absolute temperature of a target.
