Summary:The invention discloses a calibration method of a slitting mirror type infrared spectral imaging system based on a mapping matrix, and relates to the field of infrared spectral imaging. The detector is calibrated in an optical path, so that the temperature drift and non-uniformity influence are reduced, and the data quality of two-dimensional image output of the detector is improved; the disordered and unreadable two-dimensional image output is converted into an ordered and readable three-dimensional data cube by adopting three-dimensional reconstruction based on a mapping matrix; finally, the three-dimensional data cube is calibrated through intensity normalization and image geometric correction, and the quality of the three-dimensional data cube is improved. According to the invention, the original spectral data of the splitting mirror type infrared spectral imaging system can be read orderly, and the spectral data processing of the whole splitting mirror type infrared spectral imaging system can be realize
