Abstract

The invention discloses a method and a system for detecting a device with infrared tracking and beacon light pointing functions, belongs to the field of mechanical engineering, and aims to solve the problem of multi-path large-beam divergence angle parallelism adjustment precision, and the system used by the method comprises a detection target unit, a plurality of calibration rings, a plurality of cubic prisms and a mounting frame; the calibration reflector unit comprises a large-aperture reflector adjusting frame; the detection camera unit is used for detecting a camera and a tripod; the tested unit comprises a multi-path parallel light transmitting mirror group, a multi-path large-beam divergence angle transmitting mirror group and an infrared tracking calibration prism; the theodolite unit comprises a theodolite and a theodolite adjusting table; the position and the angle of a detection target are calibrated through a theodolite, a calibration reflector and a parallel light emission mirror group by taking the optical axis of a lens of an infrared detector as a reference, then multiple paths of beacon light with a beam divergence angle of 1 degree are installed, and the angles of the multiple paths of beacon light are calibrated through a calibration ring on the detection target, so that the parallelism of the multiple paths of beacon light meets index requirements; the problem of large-beam divergence angle beacon light parallelism adjustment is solved.

Description

technical field [0001] The invention relates to a detection method and system for a device with infrared tracking and beacon light pointing functions, which solves the problem of parallelism installation and adjustment accuracy of multi-channel large beam divergence angles, and belongs to the field of mechanical engineering. Background technique [0002] The infrared tracking and beacon light pointing function device provides five channels of beacon light for the host with a maximum distance of 2 meters and a parallelism better than 0.3°. The device mainly completes the capture and stable tracking of the host under airborne conditions. After successful tracking, actively pointing beacon lights are emitted to provide the host with a set of five real-time actively pointing beacon lights. [0003] The solution needs to meet the tracking under all-day conditions. The device needs to have infrared tracking function and 5-way beacon light pointing function. It has strict requireme...
