Non-overlapped stereo imaging for virtual reality headset tracking

A method comprising:

• receiving image data of an environment of a virtual reality (VR) headset, the image data captured by a first camera and a second camera coupled to the VR headset and each having a field of view, wherein at least a portion of the fields of view of the first camera and the second camera do not overlap;
• performing a simultaneous localization and mapping (SLAM) algorithm on image data received from the first camera to obtain a first direction vector, the first direction vector representing a velocity direction of the first camera as the VR headset was moved from an initial position to a new position;
• performing a SLAM algorithm on image data received from the second camera to obtain a second direction vector, the second direction vector representing a velocity direction of the second camera as the VR headset was moved from the initial position to the new position;
• computing a relative local velocity representing a relative velocity between the first camera and the second camera as the VR headset was moved from the initial position to the new position;
• and
• determining the new position based on the first direction vector, the second direction vector, and the relative local velocity.

A non-transitory computer-readable storage medium comprising computer program code, the computer program code when executed by a processor causing the processor to perform steps comprising:

• receiving image data of an environment of a virtual reality (VR) headset, the image data captured by a first camera and a second camera coupled to the VR headset and each having a field of view, wherein at least a portion of the fields of view of the first camera and the second camera do not overlap;
