Abstract: Techniques for performing a hardware-based image alignment process are disclosed. A relative position and orientation between a system camera and a detached external camera are determined. This process is performed using 6 degree of freedom (DOF) trackers on the system camera and on the external camera. A depth measurement, which indicates a distance between the external camera and a scene where the external camera is aimed, is obtained. The system camera generates a system camera image, and the external camera generates an image. An overlaid image is generated by using the relative position and orientation and the depth measurement to reproject the second content onto the first content.
