High-resolution strong fog-penetrating zoom camera lens with automatic dimming and control method thereof

Abstract

The present invention relates to an automatic dimming high-resolution strong fog-penetrating zoom camera lens and its control method. The optical structure of the lens includes a front fixed lens group A with a positive focal power and a focal Zoom lens group B with negative power, compensation lens group C with negative power, variable diaphragm D and rear fixed lens group E with positive power; the mechanical structure of the lens includes a square cabin body, the cabin body The front end and the rear end are respectively connected with a hood and a CCD fixing assembly through the front flange and the rear flange. The front side of the hood and the front side of the front protective sheet are also covered with a lens cover. The lens cover is integrated through a manual and automatic The opening mechanism controls the opening of the cover. The beneficial effect of the present invention is that the resolution of the lens is significantly improved, and it can be adapted to a high-definition camera, and the ability of the camera system to detect long-distance targets under hazy weather conditions such as rain, snow, and mist is improved.

Description

technical field [0001] The invention relates to the field of optoelectronic technology, in particular to an automatic dimming high-resolution strong fog-penetrating zoom camera lens and a control method thereof. Background technique [0002] Ordinary camera lenses are limited to applications under general lighting conditions. When used in hazy weather conditions such as rain, snow, and mist, the detection range of the system will be severely reduced, especially when the signal itself is very weak, which will cause the target signal to be submerged in the In the background signal, it cannot be used normally. In different geographical conditions and different time periods in the same region, the external lighting environment may change greatly. In some special occasions, the electronic shutter dimming method is not enough for the camera equipment to adapt to the environmental changes and work normally, and other auxiliary methods are needed. Auto-dimming. In addition, the tr...
