Simulation Technology for False Performance of Decoy Tank Based on Three-dimensional Modeling

In order to improve the test efficiency of decoy target in visible band and reduce the test risk， the three-dimensional modeling and simulation technology are used to replace the real tank with a simulated tank for the performance test of decoy tank. The 3D point cloud data of the simulated tank is collected by using the 3D modeling technology，and the main components of the tank are modeled in an appropriate way.The digital camouflage pattern is mapped to the 3D simulation model using the flexible mapping method to complete the construction of the simulated tank. Through coordinate transformation and perspective projection transformation，the 3D tank model and 2D background are synthesized to obtain a simulation experimental image. Through the calculated result of the similarity between the real tank and the simulated tank in the simulation experimental image and the statistical results of interpreter，it is shown that the simulation technology is feasible for the equipment test.
