Multi-band monitor with automatic synchronization and working method of multi-band monitor

Abstract

The invention discloses a multi-band monitor with automatic synchronization. The multi-band monitor comprises a visible-light lens, an infrared lens and an MCU (Micro Controller Unit) controller, wherein a direct-current motor and a precision potentiometer are fixed on the visible-light lens and the infrared lens; the MCU controller controls the rotation of the visible-light lens and the infrared lens by the direct-current motor and the precision potentiometer in sequence. The multi-band monitor also comprises an infrared detector and a visible-light camera, wherein the visible-light camera is fixed at the rear end of the visible-light camera; the infrared detector is fixed at the rear end of the infrared lens; the MCU controller is respectively connected with the infrared detector and the visible-light camera and configures working parameters of the infrared detector and the visible-light camera. The invention also discloses a working method of the multi-band monitor with automatic synchronization. The multi-band monitor and the working method have the advantages that when the focus length of one lens is adjusted, automatic following of the other lens can be achieved, so that the problem that each waveband is independently adjusted after a monitored target is discovered to cause target losing and the problems of vision-field mismatching, convenience and reliability and the like are effectively solved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a multi-band monitor with automatic synchronization and a working method thereof. Background technique [0002] With the development of the security industry, more and more manufacturers have made video surveillance equipment into long-distance, dual-band or even triple-band, which are used in the monitoring of roads, oil fields, forests, and safe cities. However, all dual-band monitoring equipment currently on the market either adjusts the focal lengths of the two lenses separately, and makes them reach basically the same field of view through human observation, or uses a zoom lens or an all-in-one camera for visible light, and directly uses a thermal image For fixed-focus lenses, the field of view does not match, and the thermal image cannot accurately locate the target. What's more, directly choose two fixed-focus lenses with matching field of view. Such a design is very incon...

Problems solved by technology

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a multi-band monitor with automatic synchronization and its working method. Adjusting the focal length of one lens and the other lens can achieve automatic follow-up, effectively solving the problem of individually adjusting each The band causes the problem of target loss, as well as the mismatch of field of view, convenience and reliability, etc.
