Fog-transmission television system based on continuous zoom lens

Abstract

The invention discloses a fog-transmission television system based on a continuous zoom lens and belongs to the technical field related to a photoelectric technology. The system comprises a fog-transmission lens module, a high definition photographing module, a fog-transmission enhancement module, a drive module and an image processing module which match with each other and are connected to work.The drive module drives the fog-transmission lens module to carry out continuous zoom, under the control of the image processing module, thereby imaging collection images. The high definition photographing module receives an instruction of the image processing module, then carries out photographing collection on the collection images and sends the collection images to the fog-transmission enhancement module for clearness processing. The fog-transmission enhancement module sends the processed collection images to the image processing module. The image processing module codes the collection images and sends out the coded collection images, thereby finishing collecting the images. The fog-transmission television system based on the continuous zoom lens provided by the invention is simple andportable in structure and is easy to operate and control. The image collection accuracy and efficiency of the fog-transmission television system are ensured, and the environment application capabilityand compatibility of the fog-transmission television system are greatly improved.

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
