Calibration method and calibration system for reference axis deviation of compound detection system

Abstract

The invention provides a compound detection system datum axis deviation calibration method and calibration system; the calibration method comprises the concrete steps: taking a weapon system projectile body coordinate system as a reference coordinate system; making a point target fixed on a truss coincide with a laser spot from a laser range finder, measuring the point target with an imaging device and the laser range finder respectively, and calculating to obtain a deviation angle [delta][zeta]ly of a deviation of the imaging device datum axis and the laser range finder datum axis around an Oy1 axis, a deviation angle [delta][zeta]lz of the deviation around an Oz1 axis and a deviation angle [delta][zeta]lx of the deviation around an Ox1 axis. The calibration system includes a complex detection system, an information processing system, a truss system and the point target. The calibration method is simple in principle, the calibration system is easy to construct, the calibration accuracy is high, and strong project implementation can be realized, the imaging device is facilitated to more accurately guide the laser range finder to complete distance measurement of the faraway non-cooperative point target, and a new method way is provided for needs of weapon system integrated miniaturized development.

Description

technical field [0001] The invention relates to the technical field of reference axis deviation calibration methods, in particular to a reference axis deviation calibration method and a calibration system for a compound detection system. Background technique [0002] In order to realize the precise relative movement with the non-cooperative target, the weapon system needs to measure the point target accurately while observing the long-distance point target, so the weapon system needs to be equipped with a composite imager and a laser range finder. detection system. The laser ranging mechanism in the traditional compound detection system is provided by the platform. This device has the characteristics of large volume, high quality, high power consumption, and fixed pointing angle. The beam divergence angle determines the size of the scanning range. In order to ensure sufficient scanning The laser beam divergence angle must be relatively wide, and the wide beam divergence ang...
