The system comprises a calibration controller configured to receive a headset model of the VR headset that identifies expected positions of each of the locators. The controller controls cameras to capture images of the VR headset while the headset is moved along a predetermined path. The images detect actual positions of the locators during the movement along the predetermined path. Calibration parameters for the locators are generated based on differences between the actual positions and the expected positions. Calibration parameters for the IMU are generated based on the calibration parameters for the locators and differences between expected and actual signals output by the IMU. The calibration parameters are stored to the VR headset."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stereo-based calibration apparatus","description":"A virtual reality (VR) headset calibration system calibrates a VR headset, which includes a plurality of locators and an inertial measurement unit (IMU) generating output signals indicative of motion ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9805512","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
