FOUR-SPECTRUM VIDEO SURVEILLANCE SYSTEM Russian patent published in 2024 - IPC H04N23/11 

FIELD: video surveillance systems.

SUBSTANCE: invention relates to spectrozonal television and relates to a four-spectrum video surveillance system. System comprises a mirror lens having matrix photodetectors with optical filters transmitting a radiant flux in the visible and middle infrared regions of the spectrum, as well as a third optoelectronic receiving channel for detecting the reflected radiant flux of external laser radiation in the near infrared region and converting it into a signal for indicating the location of the object of interest. System also includes a fourth optical-electronic channel for detecting a radiant flux in the far infrared region of the spectrum and converting it into signals of thermal images of the observed space. Generated image signals of the visible, near, middle and far infrared region of the spectrum are transmitted to a video processor, which outputs are connected through a signal switch to the input of the display device, as well as with a computing device, having a connection with a signal switch for generating signals on angular deviation of the tracking object by the yaw and pitch angle relative to the common optical axis of the video surveillance system.

EFFECT: high reliability and efficiency of video surveillance and selection of tracking objects.
