Helicopter Landing Free Attitude Target Calibration System

Abstract

The invention discloses a free attitude target calibrating system for landing of a helicopter. The free attitude target calibrating system comprises a target board and a host machine, the host machine is connected with a target calibrating instrument, a laser range finder and an inclinometer, the inclinometer is placed on a horizontal platform of the helicopter, a sensor of the inclinometer is fixed inside the helicopter, the host machine connected on a socket is measured by aerial insertion to the state of the host machine, a CCD (charge coupled device) camera of the target calibrating instrument and a calibrating mirror are integrally connected via a flange and then connected on an insert rod and directly inserted in an outer hanging frame of the helicopter, videos of the CCD camera are output to the host machine via a connecting wire, the laser range finer is formed by an observing mirror and a laser transmitting and receiving machine which is directly inserted in the outer hanging frame of the helicopter, and the observing mirror is connected with a view window via a photovoltaic conversion circuit, so that measured numerical values can be directly read via the view window. The free attitude target calibrating system is high in efficiency, fast in speed, convenient and simple to operate, and applicable to motorized and quick calibration of free attitude target of the helicopter.

Description

technical field [0001] The invention belongs to the technical field of target calibration, and in particular relates to a helicopter landing free posture target calibration system. Background technique [0002] The exterior of the helicopter is hung with a variety of instruments and equipment such as targeting systems, observation systems, and launching systems. These instruments and equipment need to be adjusted for accuracy before each use. When using the existing target calibration system, the helicopter needs to be leveled by the support device first, and then adjusted by the target board. The operation procedure is complicated and the work efficiency is low. Each target calibration takes more than 3 hours, and it is inconvenient to use. It does not meet the requirements of motorized rapid response. Contents of the invention [0003] In order to solve the above-mentioned defects in the prior art, the object of the present invention is to provide a target calibration s...
