Abstract

The invention provides a ship deformation measurement system and method. The system includes: an angular motion sensitive unit, which is used to obtain attitude information and angular increment information of the sensitive carrier relative to the inertial space through the angular motion of the three-axis gyroscope sensitive carrier; The processing unit is used to solve the attitude information and angle increment information of the sensitive carrier relative to the inertial space, and calculate the ship deformation angle estimate through Kalman filtering. This solution solves the problems of low accuracy and limited application range of the existing deformation measurement, can effectively improve the measurement accuracy of ship deformation, is simple and easy to implement, and is convenient for use under various conditions.

Description

technical field [0001] The invention relates to the technical field of inertial measurement, in particular to a ship deformation measurement system and method. Background technique [0002] As an important military strike platform in modern warfare, ships play an important role and have far-reaching significance in safeguarding national territorial waters, protecting homeland security, and expelling hostile targets. Due to the non-ideal rigid body of the ship, the surface ship will be deformed by factors such as wave fluctuations and transmitter vibration during ocean navigation, so that the equipment installed at various positions on the hull cannot directly use the attitude information provided by the main inertial navigation of the ship. , It is not convenient for each equipment to use. [0003] In order to measure the deformation attitude of each equipment area of ​​the ship, there are currently strain sensor-based deformation measurement and vision-based measurement me...
