The invention discloses a lens focusing method of an infrared imaging device, which includes receiving an induction signal output by an infrared detection chip according to an incident infrared light; wherein, the infrared light is obtained after pre-modulated infrared parallel light passes through a lens to be fixed Light; the lens is controlled by the driving device to move along the optical axis of the lens, and the corresponding infrared images of the lens at multiple positions are generated; the position corresponding to the infrared image with the best definition is selected as the fixed position of the lens. In this application, the infrared parallel light obtained through modulation is used as the light source for adjusting the relative position between the lens and the infrared detection chip. The infrared parallel light in this application is more stable and less susceptible to interference from the external environment, which is conducive to stabilizing the modulation of the lens and the infrared detection chip. The distance of the infrared detection chip reduces the difficulty of lens modulation. The present application also provides a lens focusing device and device for an infrared imaging device, which have the above beneficial effects.
Description
technical field [0001] The present invention relates to the technical field of infrared imaging equipment, in particular to a lens focusing method, device and equipment for infrared imaging equipment. Background technique [0002] Infrared imaging equipment can image the whole target in real time in the form of "face", so that the operator can initially judge the heating condition and fault location through the image color displayed on the screen and the hot spot tracking display function, and then conduct follow-up analysis, so as to achieve high efficiency, Identify problems with high accuracy. The infrared imaging device mainly includes a lens and an infrared detector. When the infrared signal enters the photosensitive area of the infrared detector through the lens, the infrared light signal can be imaged on the infrared detector. [0003] Infrared imaging equipment cannot adjust the focus after the lens is fixed, so it needs to be adjusted when the lens is fixed, so t...
