Abstract:In the measurement of the parameters of an infrared thermal imager,the radiation tem- perature difference received virtually by the thermal imager is not the original temperature difference because the radiation temperature difference can be affected by the optical reflectivity of each unit of the measurement system and the atmospheric transmission. Through the analysis of radiation energe transmission, the concept of"apparatus constant"of a two-blackbody parameter measurement unit is proposed and is simulated through modelling.The model can reduce the error caused by the radia- tion temperature difference trasmission in measurement and improve the measurement accuracy of the two-blackbody parameter measurement unit.

Abstract:According to the features of sea-sky-line in an infrared image,a sea-sky-line detection method is proposed.First,medium filtering is used to restrain the noise in an infrared image.Secondly, the infrared image coped with medium filtering is processed by using a line detection template so as to detect all of the horizontal lines in the image.Finally,the detected infrared image is scanned line by line to identify the position of the sea-sky-line.The experiment shows that this method can identify the position of the sea-sky-line and decrease the difficulty and complexity in the subsequent detection of maritime targets.
