Aiming at the simulation of visible light in the hardware in the loop simulation of image guided bomb, this paper realizes a visual simulation system by using Prime Vega simulation software. Through the shared memory technology, the visual simulation process can read the trajectory calculation data of the trajectory simulation process in real time, and refresh the scene. By using interpolation method, the smoothness of the flight trajectory of image guided bomb in visual simulation is ensured. The LOD (level of detail) technology and viewpoint center ocean model effectively save the simulation expenses of ocean scene simulation, which guarantees the simulation frame rate. Through experiment, the system simulation frame rate can reach 25 frames per second, which can meet the requirements of the real-time simulation in hardware in the loop simulation system.
