Abstract: A system and method for generating a mixed-reality environment is provided. The system and method provides a user-worn sub-system communicatively connected to a synthetic object computer module. The user-worn sub-system may utilize a plurality of user-worn sensors to capture and process data regarding a user's pose and location. The synthetic object computer module may generate and provide to the user-worn sub-system synthetic objects based information defining a user's real world life scene or environment indicating a user's pose and location. The synthetic objects may then be rendered on a user-worn display, thereby inserting the synthetic objects into a user's field of view. Rendering the synthetic objects on the user-worn display creates the virtual effect for the user that the synthetic objects are present in the real world.

Images collected from each of the cameras in this distributed aperture system have negligible or absolutely no overlap. The relative pose and configuration of the cameras with respect to each other are assumed to be known and provide a means for determining the three-dimensional poses of all the cameras constrained in any given single camera pose. The cameras may be arranged in different configurations for different applications and are made suitable for mounting on a vehicle or person undergoing general motion. A complete parallel architecture is provided in conjunction with the implementation of the visual odometry method, so that real-time processing can be achieved on a multi-CPU system.
