Double-inductor infrared camera and control method thereof

Abstract

The invention discloses a double-inductor infrared camera and a control method thereof. The double-inductor infrared camera comprises a lens group, a semi-reflecting semi-permeating lens, a visible light inductor, an infrared inductor, a control module, a visible light filter, an infrared light filter, a memorizer and a luminance inductor. The invention further discloses a double-inductor infrared camera control method which comprises the following steps: (1) acquiring ambient light illumination A; (2) judging whether the ambient light illumination A is larger than a given threshold A0, entering the step (3) if the ambient light illumination is larger than the given threshold A0, and entering the step (4) if the ambient light illumination is not larger than the given threshold A0; (3) closing the infrared inductor, and opening the visible light inductor; (4) closing the visible light inductor, and opening the infrared inductor. According to the double-inductor infrared camera and the control method, a semi-reflecting semi-permeating structure is applied in the infrared camera to achieve uniformity of monitoring visual fields; and a double-inductor structure is adopted, two inductors are driven through switching and are enabled to work in an intersection mode so that intersected receiving of visible light and infrared light images is realized, and complex calculation processes brought by simultaneous receiving of two kinds of light are avoided.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a dual-sensor infrared camera and a control method thereof. Background technique [0002] With the improvement of people's security awareness, various security surveillance cameras have been widely used. In order to realize continuous monitoring 24 hours a day, the night video recording function is very necessary. The method of realizing night vision can use conventional visible light lighting, but this method not only cannot conceal, but also exposes the monitoring target more. Covert night vision monitoring is currently using infrared camera technology. [0003] The visible light (wavelength 0.38μm-0.76μm) that human eyes can see is red, orange, yellow, green, blue, blue, and purple in order of wavelength from longest to shortest. Light with a shorter wavelength than violet light is called ultraviolet light, and light with a longer wavelength than red light is called infrared...
