Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G

Claim 7:
8. A object detection method, suitable for a virtual reality system, wherein the object detection method comprises:
capturing an environment to obtain a plurality of first frames through a plurality of first cameras of a head-mounted display (MMD), wherein the head-mounted display (HMD) is configured to be fixed on a head of a user, and the environment comprises an object;
executing the following steps using a processor of the head-mounted display:
inputting the first frames and a first map data of each of the first frames into an object detector; and
capturing the environment to obtain a plurality of second frames using a plurality of second cameras in a tracker, wherein the tracker is configured to be fixed on a limb of the user;
wherein the tracker transmits the second frames and a second map data of each of the second frames to the object detector, and the object detector updates an environment coverage frame in response to a determination that the first map data and the second map data are different from existing data at a same location, determines a three-dimensional intersection area of the first frames and the second frames, wherein the intersection area comprises a plurality of target feature points corresponding to the object, and searches for an object position of the object in the first frames and the second frames according to the plurality of target feature points.
