A multi-band monitor with automatic synchronization and its working method

Abstract

The invention discloses a multi-band monitor with automatic synchronization, which includes a visible light lens, an infrared lens, and an MCU controller. A DC motor and a precision potentiometer are fixed on the visible light lens and the infrared lens; the MCU controller sequentially passes through the DC motor, The precision potentiometer controls the rotation of the visible light lens and the infrared lens; it also includes an infrared detector and a visible light camera. The visible light camera is fixed at the rear end of the visible light lens, and the infrared detector is fixed at the rear end of the infrared lens. The visible light camera is connected, and the working parameters of the infrared detector and the visible light camera are configured; the invention also discloses a working method of a multi-band monitor with automatic synchronization. When the present invention adjusts the focal length of one lens, the other lens can achieve automatic follow-up, which effectively solves the problem of target loss caused by individually adjusting each band after the monitoring target is found, and the problems of field of view mismatch, convenience and reliability, and the like.

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...
