Abstract
The present disclosure provides a method and a device for aligning a coordinate of a controller or a headset with a coordinate of a binocular system. The method includes: obtaining pose data of the controller; acquiring real-time coordinate data in a binocular coordinate system during a repeating movement of the controller based on a light spot emitted from the controller; generating a motion track of the controller during the movement based on the real-time coordinate data and the pose data; obtaining a pose of the controller in controller coordinate system based on the motion track; obtaining a first angle between the positive direction of the controller coordinate system and a positive direction of the binocular coordinate system; and correcting the binocular coordinate system based on the first angle until the angle reaches zero. The method and device for aligning coordinates is easy to be implemented with low cost.
