Focusing and zooming control system of integrated optical equipment

Abstract

The invention discloses an focusing and zooming control system of integrated optical equipment, relates to the technical field of optical control, and aims to solve the problem that it cannot be ensured that a focused image is the clewest image. The system specifically comprises a microprocessor, a digital image acquisition unit, a digital image processing unit, a storage unit and a driving unit,the microprocessor is a control center; the signal output end of the digital image acquisition unit is in communication connection with the digital image processing unit, and the signal output end ofthe digital image processing unit is in communication connection with the microprocessor; and the switch control end of a driving unit is electrically connected with the microprocessor. The digital image acquisition unit is driven by the driving unit to move within a small range, continuously acquires images, performs image quality evaluation on a series of acquired images through the digital image processing unit, judges whether an iris part is imaged clearly or not, completes a focusing process, and thus, obtains the clewest image through comparison.

Description

technical field [0001] The invention relates to the field of optical control technology, in particular to an integrated optical device focus adjustment and zoom control system. Background technique [0002] The existing focal length adjustment system of optical equipment generally provides rotational power through a motor, and then converts the rotational power into linear motion power through a secondary transmission mechanism to push the optical lens (group), thereby realizing the function of focusing / zooming. At present, most of the dimming and focusing systems of optical lenses in practical applications rotate the lens cam, and the grooves on the cam drive the lens in the lens to move, thereby realizing the functions of focusing and dimming of the lens. The mechanical structure of this dimming and focusing method is complicated, and the requirements for mechanical designers are relatively high. During operation, the error caused by the large return distance difference of...
