  • Virtual reality system and object detection method applicable to virtual reality system
    Patent number: 11960082
    Abstract: An object detection method is suitable for a virtual reality system. The object detection method includes a plurality of first cameras of a head-mounted display (HMD) to capture a plurality of first frames. A plurality of second frames are captured through a plurality of second cameras in a tracker, wherein, the object detector searches for the object position in the first frames and the second frames.
