Embodiment Construction

[0026] combine figure 1 with figure 2 The hardware system describes the hardware system:

[0027] Reflector 2 is placed at the front end of the system to obtain light energy. It adopts a large-diameter fixed-focus reflector, which can accept light waves from visible light to near-infrared bands within a wavelength of 360nm to 940nm, thereby obtaining more light waves than visible light. Intensifier 15, nighttime CCD camera 13, and daytime CCD camera 10 can respond to the light wave bands that match, and have a mirror CCD interface 18 for installing the CCD camera.

[0028] The day-night switching system implements day-night mode switching under the illuminance that the day-night imaging system can respond to, so that it can be effectively coupled with the CCD interface 18 of the mirror, and the distance error in each direction of the dynamic coupling at this place does not exceed 1 mm, so as to avoid light energy loss as much as possible. Purpose, consists of stepper motor ...

Abstract

Using CCD camera, image intensifier, reflecting mirror with large caliber and laser projector, Remote all-weather automatic intelligent monitoring instrument is applicable to environment under normal illumination, low illumination even 0 LUX illumination. The instrument is composed of hardware system and software system. The hardware includes reflector, day and night switching system, daylight image system, night image system and laser illumination system. The software includes control module, image process module, correction module for atmospheric disturbance, and module for correcting and capturing images. The invention is capable of recognizing persons at 10 km under normal illumination, or at 1-4 km under 0 LUX, or at 6 km under 0.00 LUX. The instrument possesses functions of zooming target, automatic switching day and night, image capture and recording. The invention is applicable to frontier defense, public security for monitoring important area and searching object etc.

Description

Technical field: [0001] The invention relates to a long-distance monitoring instrument that works under various illuminances. More specifically, in addition to working under normal illuminances, it can work all-weather under extremely low illuminances, even 0LUX illuminances, and can be observed and identified during the day Targets such as people, ships, and vehicles within 1-10 kilometers can be observed and identified at night, such as people, ships, and vehicles within 1-6 kilometers. The long-distance monitoring instrument with laser lighting mainly belongs to the field of low-light night vision technology. technical background: [0002] The low-light night vision product is a very mature product, a technology developed from the 1970s. In the domestic market, low-light night vision products, including night vision products with laser lighting, have an effective distance of 2 kilometers for the farthest identification of people, a minimum identification illumination of 0...
