Infrared/ glimmer image fusion night vision system

Abstract

The invention discloses an infrared / glimmer image fusion night vision system, which consists of a glimmer object glass group, a glimmer image intensifier, an infrared object glass group, an uncooling long-wave infrared detector, an image processing circuit module, an electric signal transmission line, an OLED (organic light emitting diode) minitype display, an integrated optical prism and an eye lense system. The night vision system takes a glimmer image as the background, and the image fusion of a glimmer channel and an infrared channel is realized in a mode that a pseudo-color infrared target is optically projected. In order to obtain the good image fusion effect, the glimmer object glass group and the infrared object glass group both satisfy one time of magnifying power; an infrared image is subjected to denoising and enhancing pretreatments, target extraction and the electronic registration of the image; and then, a gray level image is subjected to pseudo-color treatment and is then output to the OLED minitype display for color display. The fused image has a clear glimmer background and an outstanding infrared target. The night vision system has the advantages of small size and light weight, can work for a long time and is especially suitable for night vehicle driving and for a single person to carry, observe and use.

Description

technical field [0001] The invention belongs to the technical field of optical imaging, and in particular relates to an infrared / twilight image fusion portable night vision system based on infrared target extraction and pseudo-color technology. technical background [0002] There are mainly two types of night vision equipment: low-light and infrared, each with its own advantages and disadvantages. The advantage of low light is that the visual experience is close to visible light, and it can well identify objects with different reflectances for visible light. The disadvantage is that it is not sensitive to temperature and it is difficult to detect hidden targets; the advantage of infrared is that it is very sensitive to temperature and can be very good. The temperature difference target is detected, and the detection distance is long, and it has the ability to penetrate smoke. The disadvantage is that it is difficult to identify the scene target with a very close temperature....
