Problems solved by technology
The existing target calibration method is to use the original method of topping the aircraft, aligning, erecting a target or drawing a target map, and then adjusting the target for weapon system target calibration. This method is time-consuming, laborious, low in efficiency, and low in accuracy. The complex structure of the equipment seriously restricts the efficiency of target calibration work, the hit rate of weapons and the speed of dispatching large aircraft groups

The invention discloses an optical axis calibration device for an airplane airborne laser range finder. The optical axis calibration device comprises a target calibrator host and a main control unit.The target calibrator host comprises an optical system, an image processing unit and an inertia measuring instrument which are installed in a machine shell. A heading axis direction of the inertia measuring instrument is consistent with an optical axis direction of the optical system; a laser emitted by a laser range finder is attenuated and then focused and imaged on an image sensor to form an image point; and the main control unit calculates an attitude angle parameter of the optical axis of the laser range finder according to angle data of the inertia measuring instrument and axial deviation angle data of an image processing unit. In the invention, calibration of the optical axis of the laser range finder is realized through combination of the optical system and the inertia measuring instrument, calibration precision is high, usage is convenient and fast, and the device is not only suitable for airplanes (helicopters) under maintenance and assembly conditions, but also can be used in ship-borne, hangars, strong wind or narrow and messy working spaces.
Description
technical field [0001] The invention belongs to the technical field of weapons and equipment, and relates to an optical axis calibration device and method for an aircraft airborne laser range finder. Background technique [0002] Armed aircraft (helicopters) can carry missiles, rockets, cannons, bombs and other weapons to carry out air strikes on enemy targets. The strike effect depends on the accuracy of the weapon system. However, in actual use, due to the influence of factors such as temperature, shock, vibration and fatigue deformation, the aiming accuracy of the weapon system will change. School, referred to as the school target. [0003] Target calibration is the general term for all calibration and adjustment operations that coordinate the optical, electrical, and mechanical axes of each device in the weapon system with the reference coordinate axis or maintain a certain spatial position relationship. It is a regular, directly related to the airborne It is an impo...
