An infrared night vision device gain system

Abstract

The invention provides a gain system of an infrared night vision device, comprising: an image capturing unit for acquiring a target scene image; a processor having an image processing module and an analog module, and a gain module having a communication unit and a high voltage unit, The high-voltage unit is used to form a unit of simulated temperature successively, so as to perform temperature compensation of one unit successively on the temperature distribution simulated by the analog module; the detection unit is configured as a detection unit and a comparison unit, and the detection unit is used to control the temperature distribution of the analog module. The temperature distribution simulated in the middle is detected in real time, the comparison unit is used to compare the temperature distribution simulated in the analog module detected by the detection unit with the set threshold value, and the gain control unit is used to control the temperature gain of the high voltage unit; and control A section for controlling whether the gain control unit is allowed to perform the temperature gain control of the high voltage unit based on the comparison result acquired by the comparison unit.

Description

technical field [0001] The invention relates to the technical field of infrared night vision devices, in particular to an infrared night vision gain system. Background technique [0002] Infrared night vision device is a night vision device using photoelectric conversion technology. It uses infrared searchlight to illuminate the target and receives reflected infrared radiation to form an image. The specific principle is: the phased array on the infrared detector can scan the converged light. The detector is capable of generating a very detailed temperature pattern map, called a thermogram. The detector array can obtain temperature information and make a thermogram. This information is obtained from thousands of detection points in the field of view of the detector array, but when the target is far away or the temperature of the target itself is low, the temperature spectrum of the target obtained is weak and cannot be accurately obtained Target, in the existing disclosed t...

This information is obtained from thousands of detection points in the field of view of the detector array, but when the target is far away or the temperature of the target itself is low, the temperature spectrum of the target obtained is weak and cannot be accurately obtained Target, in the existing disclosed technology, for example, the patent document with the publication number: "CN112509010A", which discloses a multi-target tracking method for an infrared imager, which discloses the first temperature distribution corresponding to the first temperature region by using a high-voltage module Perform temperature compensation step by step according to a unit amount, so that the first temperature distribution lower than the set basic threshold is within the range of the basic threshold, and then directly output these first target groups, so as to obtain a clearer target image
