Self-stabilization target tracking technology based on mobile platform

The self-stabilization tracking technique is the key technique for theodolite tracking based on the mobile platform.To improve the tracking and positioning accuracy,the self-stabilization tracking technique based on mobile platform was studied.In the technique,the position of object was transformed from the platform coordinate system to the earth coordinate system by using coordinate transform.A method of forecast tracking technique based on mobile platform was presented.The former complex angle was transformed from the platform coordinate to the earth coordinate and the next complex angle was forecasted according to the trajectory of the complex angle.In the end,the forecast result was transformed back to the platform coordinate.By this means,the stable tracking technique based on mobile platform was realized.In comparison with the direct forecast result in platform coordinate,the forecast technique presented in the paper is more accurate and appropriate to realize stable tracking on mobile platform.
