Method for calibrating an augmented reality device

A device comprising:

• a first sensor and a second sensor configured to capture sensor data;
• a memory device configured to store a calibration profile modeling a spatial relationship between the first sensor and the second sensor, the calibration profile including a translation parameter and a rotation parameter;
• a processor coupled to the first sensor, the second sensor, and the memory device, wherein the processor is configured to perform operations comprising:
• determining a calibration level associated with the calibration profile at a first time;
• and
• determining, based on the calibration level, to perform either a first calibration process or a second calibration process;
• wherein performing the first calibration process includes:
• generating a calibrated rotation parameter;
• and
• replacing the rotation parameter with the calibrated rotation parameter;
• wherein performing the second calibration process includes:
• generating both a calibrated translation parameter and a calibrated rotation parameter;
• and
• replacing both the translation parameter and the rotation parameter with both the calibrated translation parameter and the calibrated rotation parameter.

A non-transitory computer-readable medium for calibrating a device having a first sensor and a second sensor, the non-transitory computer-readable medium comprising instructions that, when executed by a processor, cause the processor to perform operations including:

• capturing sensor data using the first sensor and the second sensor, wherein the device maintains a calibration profile to model a spatial relationship between the first sensor and the second sensor, the calibration profile including a translation parameter and a rotation parameter;
• determining a calibration level associated with the calibration profile at a first time;
• and
• determining, based on the calibration level, to perform either a first calibration process or a second calibration process;
• wherein performing the first calibration process includes:
• generating a calibrated rotation parameter;
• and
• replacing the rotation parameter with the calibrated rotation parameter;
• wherein performing the second calibration process includes:
• generating both a calibrated translation parameter and a calibrated rotation parameter;
• and
• replacing both the translation parameter and the rotation parameter with both the calibrated translation parameter and the calibrated rotation parameter.
