Abstract

The invention belongs to the technical field of optical engineering and particularly relates to an optical axis alignment device and method based on camera imaging. The optical axis alignment device comprises a first guide rail, a second guide rail, a third guide rail and a computer, wherein the first, second and third guide rails are arranged sequentially in a same horizontal plane and the computer is used for analyzing camera image coordinates; the second guide rail is parallel to the third guide rail and perpendicular to the first guide rail; a camera and a first division plate are mountedon the first guide rail, a second division plate is mounted on the second guide rail, and a third division plate is mounted on the third guide rail; an optical axis where the center of the first division plate and the center of a lens of the camera locate is a fixed optical axis; an optical axis where the center of the second division plate and the center of the third division plate locate is an adjustable optical axis. An imaging method is used in alignment and is as precise as alignment by direct observation via a theodolite and is universal in engineering applications.

Description

technical field [0001] The invention belongs to the technical field of optical engineering, and in particular relates to an optical axis alignment device and an optical axis alignment method based on camera imaging. Background technique [0002] In the field of optical engineering technology, it is often necessary to calibrate and calibrate the optical axis. Traditional optical axis alignment methods use the linear propagation characteristics of light and require the help of various calibration instruments. For example, when laser is used for optical axis alignment, it can be considered that the positions passed by the laser are all on the same optical axis. The laser has the advantages of simple structure, small size, and convenient operation. However, since the laser spot diameter has a certain size, and the farther the propagation distance is, the larger the spot diameter is, it is difficult to accurately align the optical axis, so the laser alignment method is only appli...
