Abstract

In this paper, a lightweight method of velocity and direction measurement based on passive location and linear fitting for airborne electro-optic system is proposed. This method can realize real-time and high-precision, well applicability for long-distance target, without laser ranging equipment or more computer resources. The algorithm uses the data of GPS model, and attitude data of electro-optic system to locate the target passively with a high frequency. It uses the least square fitting method to find the trajectory of the target, and then, get a new point set with point-line projection. At last, the method of weighted mean and the method of polar coordinate are used to calculate the velocity and direction of the target.
