Abstract: The mixed test technology in automobile industry is reviewed, and the potential of such technology in test of ship intelligent navigation is studied. The objects, contents, challenge and countermeasures involved in intelligent navigation tests are analyzed and the method with mix of virtual and actual reality is proposed. The scene recognition, composition of the scene library, elements of scenes, and the method to optimize the system and accelerate its operation speed are summarized. Some fundamental things are discussed, such as standardization of scene library and is testing, environment perception and scene generation, integration modelling, and man-machine interaction.
