A fog-through TV system based on continuous zoom lens

Abstract

The invention discloses a fog-penetrating TV system based on a continuous zoom lens, which belongs to the related technical field of photoelectric technology. It works by setting a fog-penetrating lens module, a high-definition camera module, a fog-penetrating enhancement module, a driving module and an image processing module for matching and connection work. Under the control of the image processing module, the driving module drives the fog penetration lens module to continuously zoom to image the captured picture. After receiving the instructions from the image processing module, the high-definition camera module captures the captured picture and sends it to the fog penetration enhancement module for clearing. The fog penetration enhancement module sends the processed captured picture to the image processing module, which encodes the captured picture and sends it out to complete the picture image capture. The fog-penetrating TV system based on the continuous zoom lens of the present invention has a simple and portable structure, and is easy to operate and control. It not only ensures the accuracy and efficiency of image acquisition of the fog-penetrating TV system, but also greatly improves the environmental applicability and compatibility of the fog-penetrating TV system. sex.

Description

technical field [0001] The invention belongs to the related technical field of optoelectronic technology, and in particular relates to a fog-penetrating TV system based on a continuous zoom lens. Background technique [0002] With the continuous development of TV imaging technology, it has been widely used in TV guidance, photoelectric reconnaissance and other technical fields. In the process of TV imaging, continuous zoom lens plays a very important role. Large and small targets are clearly imaged. When the target needs to be searched or observed, the short-focus large field of view is generally used, and when the target needs to be observed and tracked in detail, the long-focus small field of view is generally used, but in the process of field of view conversion , in order to prevent the observed target from disappearing, it is necessary to put forward high requirements on the consistency of the optical axis of the lens.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, fog penetration imaging usually uses infrared imaging or near-infrared television imaging. Although this can achieve fog penetration imaging of the picture to be collected to a certain extent, due to the resolution of the infrared imaging core detector (usually 640×512) is relatively low, and the pixel size (usually 17 μm) is relatively large, resulting in a large volume of the entire imaging system, which is not suitable for portable use, and cannot fully meet the needs of ultra-long-distance imaging and observation; Although the resolution of near-infrared television imaging has been improved to a certain extent and the pixel size has also been reduced to a certain extent, the existing near-infrared television imaging has poor image processing capabilities and cannot effectively adapt to the clear image of complex environments. Imaging shooting, its application has great limitations, and there is a problem of poor consistency of the optical axis in the process of continuous shooting and field of view conversion, and the imaging quality is greatly affected
