Abstract

The invention discloses external optical orientation equipment. The external optical orientation equipment comprises an antenna substrate, a first marking pole, a second marking pole and an orientation device, wherein the antenna substrate is rotationally mounted on a rotary plate and is coaxial with the center of the rotary plate; the first marking pole is fixedly mounted on the antenna substrate and is coaxial with the antenna substrate and the center of the rotary plate; the second marking pole is fixedly mounted on the antenna substrate, and the distance between the second marking pole and the first marking pole is larger than a first set distance threshold value; the orientation device is fixedly mounted on the antenna substrate, the center of the orientation device is located on the connection line of the first marking pole and the second marking pole, and the orientation device is used for measuring the azimuth angle of the connection line of the first marking pole and the second marking pole. The external optical orientation equipment is independent of to-be-oriented optical equipment and can be repeatedly used; aligning precision can be guaranteed with the adoption of optical aligning. The invention further provides a corresponding orientation method.

Description

technical field [0001] The invention belongs to the technical field of optical orientation, and more specifically relates to an external optical orientation device and a direction-finding method thereof. Background technique [0002] In general, the orientation scheme of optical instruments and equipment is usually to connect the orientation equipment including electronic compass or fiber optic gyroscope and other direction finding devices to the optical instruments. Due to the high price of directional equipment, many optical instruments and equipment are not equipped with directional equipment during design. However, when needed in later applications, it is generally more difficult to install directional equipment, and it is also more troublesome to detect and replace the instrument performance of directional equipment. [0003] Furthermore, the currently adopted fixing solution is usually to align the direction-finding device with the axis base line of the housing of the...
