Recently, the augmented reality technology has become a useful tool for assembly guidance. The projectors have been always used as virtual image output devices. In most situations, real-time and dynamic images projection is essential due to that the components to be assembled are randomly placed and movable. However, the cameras and the projectors are placed in different relative positions, making it difficult to project real time images when we are using augmented reality for assembly. A novel method based on the system of binocular cameras and projector was proposed here to overcome the limitation. We established a method to get the relations of coordinate transform among camera coordinate system, projector coordinate system and world coordinate system based on real-time internal parameter matrix of the projector that we derived. Obtaining the pose information of the cameras without any designed markers in real world was also realized, which is the key technology for the camera-projector assembly visualization system. An assembly experiment of cable laying was conducted and the results showed that using the proposed method the real-time projection for augmented reality assisted assembly was realized.
