Abstract: To solve the problem that optical measurement equipment cannot carry out practical training due to lack of cooperative target close to the actual situation of weapon equipment test，a practical training method for optical measurement equipment based on simulated target is proposed． According to the actual situation of optical measurement equipment and target，the three-dimensional model of the target is constructed with the visible light
and infrared imaging characteristics processing on the three-dimensional model respectively． The third-order
B-spline curve is used to fit the trajectory curve of the target，and the attitude control information is obtained after
the motion attitude processing． The motion characteristic model of the target is generated by encapsulating the
trajectory curve with the attitude control and characteristic events information． Using computer simulation
technology，a virtual three-dimensional space is constructed，in which the scene of optical measurement
equipment tracking and measuring target is simulated，and the simulation target is seamlessly generated on
optical measurement equipment for practical training of optical measurement equipment． The application and
verification on the in-service optical measurement equipment show that the method is feasible and practical．
