Error Analysis of Mast Mounted Electro-Optical Stabilized Platform Based on Multi-body Kinematics Theory

摘要

Error analysis of target location for Mast Mounted Electro-Optical Stabilized Platform based on multi-body kinematics theory is presented in this paper. Firstly, a typical structure of OMS, which is mounted on the reconnaissance vehicle, is introduced briefly and Multi-body kinematics theory is used to illustrate the topology structure and coordinates relations. Accordingly, target location equations between target and OMS are derived. Secondly, the characteristics and compensation methods are discussed in detail for the error analysis, which influence the system target location accuracy, such as imaging sensors errors, stabilized platform errors and equipments errors. Finally, simulation results based on Monte Carlo and experiment results are presented, showing that axis zero bit, consistency, verticality errors and equipments alignment errors are the primary factors, which influence system target location accuracy. After the compensation, the accuracy has been improved 2 orders and reached 5m/0.06°.
