Optical positioning aiming system

A method of superimposing a holographic image in a field of view of a head mounted display (mounted display), the method comprising:

• receiving user input including a selection of holographic image components to include in a holographic image;
• detecting IR emitters of a weapon and IR emitters of a mounted display;
• obtaining images from an IR camera of the weapon and an IR camera of the mounted display;
• determining whether the IR emitters are in a field of view of the IR cameras;
• in response to the IR emitters not being in the field of view of the IR camera, continuing to obtain images from the IR camera of the weapon and the IR camera of the mounted display until the IR emitters are in the field of view of the IR cameras;
• in response to the IR emitters being in the field of view of the IR camera:
• calculating an orientation and a position of the mounted display with respect to the weapon based at least partially on the IR emitters of the weapon;
• calculating an orientation and a position of the weapon with respect to the mounted display based at least partially on the IR emitters of the mounted display;
• reconciling the orientation and the position of the mounted display with respect to the weapon with the orientation and the position of the weapon with respect to the mounted display;
• determining a line of sight of a user based at least partially on the position of the IR emitters mounted on the head mounted display,
• determining a point of aim of the weapon based at least partially on the position of the IR emitters mounted to the weapon,
• determining a position of a holographic aiming reticle to be displayed within in the field of view of the mounted display based on the reconciled relative positions and orientations;
• and
• superimposing the holographic aiming reticle in the field of view at the point of aim of the weapon.

An optical positioning subsystem configured to determine relative positions of a weapon and a head mounted display and to generate and position a holographic image into a field of view of the head mounted display, the optical positioning subsystem including:

• an infrared (IR) emitter mounted to a weapon;
• an IR emitter mounted to the head mounted display;
• an IR camera mounted to the weapon that receive an IR signal emitted from the IR emitter mounted to the head mounted display;
• an IR camera mounted to the head mounted display that receive an IR signal emitted from the IR emitter mounted to the weapon;
• and
• a processing unit,
• wherein during operation of the optical positioning subsystem, the processing unit:
• receives a first signal from the IR camera mounted to the weapon, the first signal being indicative of the IR signal emitted from the IR emitter mounted to the head mounted display and a position of the IR emitters mounted on the head mounted display relative to the weapon;
• receives a second signal from the IR camera mounted to the head mounted display, the second signal being indicative of the IR signal emitted from the IR emitter mounted to the weapon;
• determines a relative position and orientation of the weapon with respect to the head mounted display based at least partially on first signal;
• determines a relative position and orientation of the head mounted display with respect the weapon based at least partially on first signal;
• reconcile the relative positions and orientations;
• determines a line of sight of a user based at least partially on the position of the IR emitters mounted on the head mounted display,
• determines a point of aim of the weapon based at least partially on the position of the IR emitters mounted to the weapon,
• determines a position of a holographic aiming reticle to be displayed within in the field of view of the head mounted display based on the reconciled relative positions and orientations such that the holographic aiming reticle is positioned in the field of view;
• and
• superimposes the holographic aiming reticle in the field of view at the point of aim of the weapon.
