Installation Error Dynamic Correction Based on Quasi-Linear Model

In order to suppress the installation errors of photoelectric payload and increase the precision of target location using photoelectric payload equipped on the aerial mobile platform, a new method of calibrating fixing errors dynamically is proposed based on quasi-linear model. The method analyzes the relationship between measurement data and true value and comes to a quasi-linear conclusion between them under some conditions. The new method is used to real-time dynamically calibrating installation errors of photoelectric payload, which improves the precision of target location effectively. Both the simulation and the experiment prove the validity of the method. It is easy to calculate and be put into practice. Furthermore, the new method could meet the real-time need and is of high value to application.
