Abstract

The invention relates to a target infrared image real-time quantitative processing system with environment adaptivity. The system comprises an infrared measurement unit which is used for obtaining a target infrared digital image, wherein the infrared measurement unit at least comprises an infrared detector; a real-time quantitative processing unit which is used for converting the target infrared digital image into a target infrared radiation image represented by radiation temperature based on a practical calibration coefficient and an atmospheric calibration parameter of the infrared detectorobtained through computing; and an infrared calibration unit which is used for providing testing data in order to obtain the practical calibration coefficient and the atmospheric calibration parameter. According to the system, a current practical calibration coefficient of the infrared detector is computed in real time, so calibration precision of the infrared detector is ensured, data processingtimeliness of the target infrared digital image is ensured.

Description

technical field [0001] The invention relates to the technical field of target infrared data quantitative processing, in particular to a real-time quantitative processing system of target infrared image with environmental adaptability. Background technique [0002] Quantitative analysis of the infrared characteristics of the target is the premise of the analysis of the radiation characteristics of the target. In order to obtain the radiation characteristics of the target, it is necessary to restore the true radiation characteristics of the target with high precision, including: using sensors to collect the apparent information of the target, and then through quantitative response calibration conversion, target apparent radiation calculation, distance correction and atmospheric correction. The link realizes the quantitative extraction of the target radiation characteristics. [0003] Due to the complexity of the infrared quantitative processing process and the large amount of...
