Indoor detection method for angle tracking precision of swinging mirror

Abstract

The invention provides an indoor detection method for angle tracking precision of a swinging mirror. The indoor detection method comprises the following steps: (1) placing a plurality of parallel light tubes in a swinging mirror tracking range and pointing to the center of the swinging mirror to respectively set to a target 1, a target 2...a target n, setting the center of the swinging mirror to O; representing crossed points of connection lines of the targets and the O point, and a movement curve by A, B, C, D and the like, pointing a swinging mirror rotation starting point to the A point of the end point on a target movement curve, wherein the distance from the O point to the movement curve thetaOT is L and the L is the vertical distance from the O point to the plane where the movement curve is located; and (2) calibrating included angles including thetaAT, thetaBT, thetaCT and the like by using a total station, after calibrating, replacing the total station by a swinging mirror tracking system, wherein the thetaAT, the thetaBT and the thetaCT are the included angle of the A point and the OT, the included angle of the target 1 and the OT and the included angle of the target 2 and the OT. According to the indoor detection method for the angle tracking precision of the swinging mirror, the detection on the angle tracking precision of a high-speed movement target by the tracking system is realized by a static simulation target.

Description

technical field [0001] The invention relates to an angle tracking accuracy detection technology, in particular to an indoor detection method for an angle tracking accuracy when a pendulum mirror tracking system tracks a high-speed moving target. Background technique [0002] The high-speed oscillating mirror target tracking system is a system that uses mirror swing to reflect a moving target into a high-speed camera to achieve target recording. Due to the high angular velocity and angular acceleration of the pendulum mirror, the system can realize the tracking and attitude recording of high-speed targets. The angular tracking accuracy of high-speed moving targets is an important parameter index of the system. [0003] In order to measure the angular tracking accuracy of the pendulum mirror tracking system, it is necessary to simulate a high-speed moving target, which is difficult to achieve in the laboratory. At present, the target is mainly simulated through the dynamic i...
