METHOD FOR GENERATING SIGNALS OF MULTISPECTRAL IMAGES Russian patent published in 2022 - IPC H04N7/18 

FIELD: imaging technology.

SUBSTANCE: invention relates to the field of applied television and can be used for video surveillance and image analysis of objects in the surrounding space. It provides for the joint formation of color, spectral and thermal imaging images by registering and converting the radiant flux of the visible, near and thermal infrared regions of the spectrum into signals of multispectral images. The result is achieved by the fact that in order to generate signals of multispectral images, the input radiant flux is recorded within a wide spectral range of wavelengths, which may include the visible and infrared regions of the spectrum. Three separate streams F₁(λ), F₂(λ) and F₃(λ) are isolated from the input radiant flux F(λ). In the first opto-electronic channel on the basis of the radiant flux F₁(λ) visible region of the spectrum color television video signal U_R(t), U_G(t) and U_B(t) are shaped, in the second opto-electronic channel on the basis of the radiant flux F₂(t) visible and near infrared regions of the spectrum the video multispectral television U_Δλ1(t), U_Δλ2(t) and U_Δλ3(t) are formed and the third opto-electronic channel on the basis of the radiant flux F₃(λ) the thermal infrared region of the spectrum the video imaging U_Δλ4(t) and U_Δλ5(t) are formed using a single mirror-lens lens, providing transmission of the input radiant flux for observing the same object in two or more spectral regions within a wide spectral range of wavelengths.

EFFECT: increase in the accuracy of spatial alignment of individual multispectral images of objects in a single resulting image and an increase in the quality of visual and automatic image analysis based on information from different recording zones of the radiant flux reflected and radiated from objects.
