Description

TECHNICAL FIELD

[0002] Infrared spectrum imaging technology is the product of imaging technology and spectrum detection technology, imaging sensor can obtain the spatial position information of target, and spectrometer can obtain the spectral characteristic information of multiple wave bands corresponding to each picture element, and spectrum has the "fingerprint" characteristics of distinguishable matter, and the three-dimensional data cube obtained by combining the two technologies can determine the spatial position and chemical information of target, therefore, infrared spectrum imaging technology plays an important role in the fields of military camouflage discrimination, gas leakage early warning, natural disaster early warning, ground feature identification, ground mapping remote sensing and the like.

[0003] Different spectral resolution imaging spectrometers are suitable for different application scenarios, for example, main application scenarios of multispectral imaging include: when carrying out gas leakage detection, the gas type with leakage risk is known, therefore, the gas spectral characteristics are known, and the gas diffusion area is large and the diffusion speed is fast, under this condition, the cost of selecting multispectral imaging is low, and the data processing speed is fast; when the target is a ground feature or camouflage object with obvious geometric characteristics, the multispectral imaging image resolution is relatively high, the target can be visually interpreted first, and after basically determining the target type and spatial position, the identification accuracy of the target is improved by combining the spectral characteristics and the like. Main application scenarios of hyperspectral imaging include: when the measured target is unknown and invisible, since the multispectral wave band is wide, the target characteristics can be subtracted in the identification process, at this time, the hyperspectral imaging technology is more suitable; when the spectral characteristics of multiple targets are similar or partially overlapped, at this time, the hyperspectral information with narrower bandwidth and more details is needed to be used for identification; when the monitored gas needs to be quantitatively analyzed, under this condition, it is obviously more reasonable to select hyperspectral imaging; the two can also be used cooperatively, for example, multispectral imaging is used for "general survey", the target position and target type are determined first, and then hyperspectral imaging is used for "detailed survey", and the target material composition is analyzed in detail.
