Angular Displacement Measurement Method of Optical Platform on Moving Vehicle
摘要
Abstract
This paper proposed a new real-time measurement method of moving optical platform＇s 6-DOF liner and angular displacements by using broadband liner displacement sensors,a theoretical formula of the method was derived.The relationship among the inertial coordinate system,platform coordinate system and sensor coordinate system was established by coordinate transformation,the relation between sensor signals and platform displacement was obtained,then the 6-DOF of the platform could be calculated by the displacement signals in real time.And many factors affected on the test accuracy were analyzed.Analyses show that this method can achieve dynamic measurement of many different vibration isolation platforms＇ 6-DOF displacement under different environments by selecting different frequency bands,different accuracy sensors.This method is simple,convenient,high precision and worth spreading.关键词
