6 megapixel DC motor lens

Abstract

The invention relates to a 6-million-pixel DC motor lens, which includes a lens barrel, in which a front fixed group A, an optical focus zoom group B, a diaphragm, a rear fixed group C, a compensation group D, and a zoom group B are sequentially arranged. , The compensation group D can move back and forth correspondingly along the optical axis, and the front fixed group A includes a glued group in which the positive crescent lens A-1, the positive crescent lens A-2, the negative crescent lens A-3 and the double-convex lens A-4 are tightly bonded A, variable power group B includes biconcave lens B‑1, biconcave lens B‑2 and biconvex lens B‑3 glued group B, rear fixed group C includes biconvex lens C‑1, biconvex lens Cemented group C of lens C‑2 and negative crescent lens C‑3, positive crescent lens C‑4, compensation group D including biconvex lens D‑1, negative crescent lens D‑2 and biconvex The cemented group D of lens D-3 and the negative crescent lens D-4 have high optical index, large relative aperture, high magnification ratio, short structural length, high resolution of the lens, and can adapt to 6 million pixel high-definition video camera requirements.

Description

technical field [0001] The invention relates to a six million pixel DC motor lens. Background technique [0002] With the increasingly dense traffic network and increasingly busy traffic, in order to maintain traffic safety, prevent traffic jams, and achieve orderly under busy road conditions; it is of practical significance to provide a high-resolution, automated and adjustable lens for the development of intelligent transportation systems. Early manual zoom lenses have simple structure, low performance indicators, low level of intelligence, and poor mobility in capturing clear images. They can only be manually adjusted and assembled into the IMX226 camera. The lens cannot be directly adjusted during the shooting process. Image capture lacks initiative and can only meet the needs of monitoring within a certain range. When it is necessary to capture things outside the range, the image cannot be captured effectively, and even the license plate number cannot be read and the ch...

Problems solved by technology

Early manual zoom lenses have simple structure, low performance indicators, low level of intelligence, and poor maneuverability in capturing clear images. They can only be manually adjusted and assembled into the IMX226 camera. The lens cannot be directly adjusted during the shooting process. Image capture lacks initiative and can only meet the needs of monitoring within a certain range. When it is necessary to capture things outside the range, the image cannot be captured effectively, and even the license plate number and the characteristics of the characters cannot be seen clearly.

This kind of control technology is far from meeting the requirements of the current camera and the society's demand for the quality of the monitoring system.
