Problems solved by technology

Due to structural limitations, the TV lens does not provide an optical reference, so the optical axis of the TV lens cannot be determined. At present, when the existing TV lens and CCD components are assembled and debugged, the center of the CCD cannot be adjusted to the optical axis of the TV lens. Butt the TV lens and CCD based on experience, resulting in the picture of the display is not clear enough

Abstract

The invention provides an imaging adjustment method for a television camera. The imaging adjustment method includes the steps: fixing the television camera on a turntable of a rotary centering device; erecting a collimator with a cross reticule above the television camera; adjusting the angle of the television camera to fix a crosshair image received by a lower internal focusing telescope; fixing an adjustable reflector above the television camera and adjusting the angle of the reflector to fix a cross reticule image reflected into the collimator by the adjustable reflector; mounting the television camera with the adjustable reflector on a television component debugging platform and adjusting the collimator by taking the normal line of the adjustable reflector as a reference; and removing the adjustable reflector and adjusting the position of a CCD (charge coupled device) by taking the collimator with a discrimination plate as a reference to form the clearest picture. The imaging adjustment method is applicable to all television cameras and high in practicability, a real optical axis of each television camera can be accurately determined, and an accurate optical reference is provided for adjusting television components.

Description

technical field [0001] The invention belongs to optical-mechanical adjustment technology, in particular to an imaging adjustment method of a television lens. Background technique [0002] When the TV assembly is assembled and adjusted, the TV lens and the CCD element are two separate units. Due to structural limitations, the TV lens does not provide an optical reference, so the optical axis of the TV lens cannot be determined. At present, when the existing TV lens and CCD components are assembled and debugged, the center of the CCD cannot be adjusted to the optical axis of the TV lens. Butt the TV lens and CCD according to experience, resulting in the picture of the display is not clear enough. Contents of the invention [0003] The purpose of the present invention is to provide a method for adjusting the image of a TV lens, which can adjust the center of the CCD to the optical axis of the TV lens to make the picture clear. [0004] In order to solve the above-mentioned ...
