Description

Technical Field

[0001] The invention relates to the field of calibration measurement, in particular to a device for rapid calibration of the azimuth and height of shipborne artillery and land-based artillery. Background Art

[0002] During the calibration and measurement of shipborne and land-based artillery, it is necessary to unify the azimuth, altitude and pointing of the relevant equipment with the reference azimuth and altitude of the ship or land. The current calibration and measurement equipment uses the theodolite and the aiming telescope on the calibration equipment to aim at the stars at the same time, unify the pointing of the equipment with the azimuth and altitude reference of the theodolite, and then aim the theodolite at the reference line of the ship or land to achieve the unification of the equipment with the reference azimuth and altitude of the ship or land. However, due to the structural problems of the calibration equipment, the following problems exist in its use: 1) In the process of aligning the theodolite with the reference plane of the ship, the efficiency is low, the adjustment time is long, and the technical requirements are high; 2) When the theodolite and the equipment are aimed at the stars, the selection of stars generally relies on the human eye to distinguish in the air, resulting in the selected stars not being optimal in terms of altitude angle, brightness, etc., and when the calibration time is too long and the earth rotates during this period, the selected stars cannot be effectively used to complete the entire calibration measurement process; 3) When the theodolite is used to aim at the stars, the surveyor needs to continuously observe the instrument for aiming and tracking, which consumes a lot of time and energy of the surveyor, and cannot realize the automatic tracking and aiming of the theodolite to the stars; 4) When the star sighting mirror on the equipment is used to aim at the stars, the equipment needs to be continuously rotated to keep the equipment and the stars in an aligned state, which takes a long time and is labor-intensive, and it is difficult to achieve the aiming mirror to roughly aim at the stars and the precise aiming angle; 5) The data synchronization between the theodolite and the star sighting mirror needs to be synchronized through voice commands, which is inefficient; 6) Data processing requires on-site calculation and inference, with low processing efficiency and poor accuracy and reliability. Therefore, improvement and innovation in calibration equipment are imperative. Summary of the invention

[0003] In view of the above situation, in order to solve the defects of the prior art, the purpose of the present invention is to provide a rapid calibration equipment for the azimuth and altitude of shipborne artillery and land-based artillery, which can effectively solve the problems of difficult operation, low working efficiency, poor aiming angle accuracy, and poor accuracy and reliability of the original equipment.

[0004] The technical solution solved by the present invention is to include a hollow shaft, a camera, a multi-channel interface communication power supply controller and a tablet computer.

The center of the hollow shaft and the center of the lens at the front end of the camera are on the same axis to form an aiming structure. The camera data interface on the camera is connected to the camera communication interface of the multi-channel interface communication power supply controller via a transmission line. The multi-channel interface communication power supply controller is connected to the tablet computer via a network data interface by wire or wireless.
