  • Patent number: 10839527
    Abstract: A method of measuring infrared spectral characteristics of a moving target, the method including: establishing a multi-dimensional and multi-scale model with infrared spectral features of an object-space target, and extracting an object-space region of interest measurement model; performing target detection on an actually measured infrared image, and identifying position information for each ROI of a target; tracking the target, to obtain the target's pixel differences between two frames, as well as a moving direction of the target, and performing motion compensation for the target; and scanning the target, and after successfully capturing an image of the target being tracked, controlling an inner framework to point to each target of interest, and according to moving-direction information of the target, performing N-pixel-size motion in a direction shifted by 90° with respect to the moving direction, and activating a spectrum measuring module.

  • Publication number: 20190323894
    Abstract: A method of attitude estimation of a spotted target. The method includes an offline training and an online estimation. The offline training includes establishing a three-dimensional geometric model of a target, performing region division according to the structure of the target, establishing an object-space temperature distribution model for each region of the target, establishing an infrared radiation transmission model of an intra-atmospheric target in six attitudes in observation by a detection system, constructing an image-space radiant energy model of the target in the six attitudes using the object-space temperature distribution model and the infrared radiation transmission model, and performing simulation calculation to obtain an infrared spectral curve of the spotted target regarding wavelength versus image-space-radiant-energy-of-target, so as to establish a mapping database regarding target-attitude versus spectrum.

  • Patent number: 9921102
    Abstract: A moving platform borne infrared image-spectrum associated detection system includes an optical hood, a broadband optical system, a two-dimensional servo system, an infrared optical fiber, a Fourier interference spectrum module, an image-spectrum associated detection processing module, a power supply module, and a display module. Incident light enters from the optical hood to the broadband optical system, and is split by a spectroscope. Transmitted light is focused by a long-wave imaging lens group on an infrared detector for imaging. Reflected light is focused by a broadband spectrum lens group to an optical fiber coupler, enters the Fourier interference spectrum module through the infrared optical fiber to form an interference pattern, and undergoes Fourier transform to obtain spectral data.
