Abstract

The embodiment of the invention provides a camera zoom optical system optical axis consistency adjusting method and a display instrument. When a zoom optical lens of a camera and an image sensor are assembled, the coincidence adjustment of the long-focus optical axis and the short-focus optical axis and the image center of the image sensor is assisted, a position needing to be adjusted is directlydisplayed by superposing an icon on an original image, and the adjustment efficiency of optical axis consistency adjustment can be greatly improved.

Description

technical field [0001] The invention relates to the field of photoelectric imaging, in particular to a method for adjusting the optical axis consistency of a zoom optical system of a camera and a display device. Background technique [0002] In photoelectric imaging equipment, if the optical center of the optical lens is called the optical axis, the image center of the image sensor is called the visual axis. Due to reasons such as processing and assembly, the optical center of the zoom lens is often inconsistent, so that the center of the field of view of the captured image During the zooming process, there will be an offset, which will affect the observation and aiming of the target. For photoelectric measurement and positioning equipment, this will introduce measurement errors, which will affect the accuracy of the entire equipment. For a camera with a large zoom ratio, if the deviation is large, it may even cause the target originally aimed at the center of the field of ...
