In order to meet the development requirements of the new generation aerial electro-optical system, a software modeling method based on UML is proposed by using object-oriented design idea. On the basis of analyzing the characteristics of the aerial electro-optical system software, the software modeling research is carried out from different angles by using the use case diagram, the behavior diagram, the interaction diagram, the static diagram and the implementation diagram in UML, and the characteristics and differences of each kind of diagram are expounded. The results show that the UML-based software modeling method can establish a clear and intuitive software design model, reduce the complexity of software design, lay the foundation for software coding implementation, and have a guiding significance for the development and design of a new generation aerial electro-optical system software.
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.
