Embodiment Construction

[0031] refer to figure 1 , The device of the present invention includes an optical system (fog penetration and night vision), a photoelectric conversion system, an image signal processing system, an automatic control system, and a DSP real-time image enhancement system.

[0032] The multi-spectral camera drives the filter to switch on the imaging optical path by controlling the motor, so that the imaging beam passes through the filter or does not pass through the filter, so as to achieve the purpose of imaging the imaging beam in the near-infrared band or near-infrared + visible light "full band" imaging; By controlling the rotation of the motor, the imaging device is driven to move back and forth along the optical axis, so that the target surface coincides with the image surface and the imaging is clear. The specific implementation is as follows:

[0033] 300mm focal length objective lens;

[0034] Model: 20X80LE

[0035] Parameters: focal length f 300mm

[0036] Ca...

Abstract

The invention discloses a fog-penetrating and night-vision system based on a refrigeration type CCD element. The fog-penetrating and night-vision system is a device detecting the emitted or reflected light of objects in different wave bands (visible light and near-infrared band) and realizing imaging; the functions of fog-penetrating and night-vision of the device are greatly enhanced; the refrigeration type CCD element is used to increase the resolution ratio and sensibility of the imaging system; high-performance real-time image fusion and enhancing treatment algorithm is adopted, and all-weather remote target detection and imaging can be realized with low cost.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, in particular to a fog penetration and night vision detection system using a refrigeration type CCD device. Background technique [0002] The main factors that affect visibility during the day are fog and haze. Photoelectric products must have a certain ability to penetrate fog in order to effectively solve the problem of detection distance. At night, in the absence of light, it is difficult for ordinary photoelectric sensors to detect long-distance targets. [0003] In the photoelectric detection technology, digital cameras have gone through several stages of vacuum tubes, transistors and integrated circuits, and microelectronic solid-state imaging devices. system etc. The optical system is composed of a lens, a color temperature filter, and a red, green, and blue spectroscopic system to obtain three primary color images of red (R), green (G), and blue (B) that are imaged on the...
