DUAL-SPECTRUM VIDEO SURVEILLANCE SYSTEM Russian patent published in 2022 - IPC H04N5/33 H04N7/18 

FIELD: television.

SUBSTANCE: present invention relates to the field of multispectral television and pertains to a dual-spectrum video surveillance system. System comprises a mirror-lens objective with a first and a second matrix photodetectors. Optical filters for the visible and infrared spectral regions are included in front of the first and second matrix photodetectors. Mechanical adjustment units for adjusting the relative positioning of the first and the second matrix photodetectors in six degrees of freedom are also included in the mirror lens objective for each matrix photodetector. Additionally, a unit for digitally spatially aligning individual elements of the image in the visible and infrared regions is included between the output of the matrix photodetectors and the video processor, and a video signal switch is included between the video processor and the video monitoring apparatus.

EFFECT: higher accuracy of elementwise combination of two multispectral images in a single resulting image and higher reliability and effectiveness of video surveillance and analysis of objects.
