Wearable display device calibration

A method, comprising:

• emitting a first reference beam from a first display lens system that forms an image of an environment as viewed through the first display lens system;
• capturing a first reflection image of the first reference beam;
• emitting a second reference beam from a second display lens system that forms the image of the environment as viewed through the second display lens system;
• capturing a second reflection image of the second reference beam;
• comparing the first and second reflection images to determine a misalignment between the first and second display lens systems;
• and
• applying an alignment adjustment to align the image of the environment formed by each of the first and second display lens systems.

A wearable display device, comprising:

• a left display lens system for augmented reality imaging configured to emit a first reference beam with a first near infra-red laser;
• a right display lens system for the augmented reality imaging configured to emit a second reference beam with a second near infra-red laser;
• a left camera configured to capture a first reflection image of the first reference beam;
• a right camera configured to capture a second reflection image of the second reference beam;
• an imaging application configured to:
• compare the first the second reflection images to determine a misalignment between the left and right display lens systems;
• and
• align the augmented reality imaging of the left and right display lens systems based on the determined misalignment.
