Abstract

The invention belongs to the parameter calibration technical field and relates to a dynamic parameter calibration device of an optical tracking / sighting pointing system and a use method of the dynamic parameter calibration device. The objective of the invention is to solve the problem that an optical tracking / sighting pointing system cannot be calibrated in the prior art. The device comprises a carrier attitude simulation system (1) and a target simulator (2); equipment to be tested (3) is mounted on the carrier attitude simulation system (1); the carrier attitude simulation system (1) simulates six-degree-of-freedom motion in a three-dimensional space and reproduces the attitude change of a carrier; and the target simulator (2) is mounted on a platform at a certain height, and is spaced by a certain distance, and simulates the movement trajectory of the movement of a target. The method includes the steps of stabilization accuracy calibration and tracking accuracy calibration. According to the dynamic parameter calibration device of the invention, the carrier attitude simulation system is adopted to simulate six-degree-of-freedom motion in the three-dimensional space, and can simulate the use environments of the system under vehicle-mounted, ship-based, airborne and ground-based conditions to the greatest extent.

Description

technical field [0001] The invention belongs to the technical field of parameter calibration, and in particular relates to a dynamic parameter calibration device of an optical tracking / aiming system and an application method thereof. Background technique [0002] Optical tracking / aiming system, as an opto-mechanical-electrical integration device with functions of imaging, capturing, tracking, aiming and measuring, has developed rapidly in the fields of aviation, spaceflight, ships and weapons in recent years. The optical tracking / aiming system uses the motion characteristics, geometric characteristics, physical characteristics of the target object and the optical characteristics of the target background to sense, track and aim the target, and can output information such as the position, speed and acceleration of the target object. Compared with radar, the optical tracking / aiming system can track and aim at medium and short-distance targets, and has the advantages of visibili...
