1. A virtual reality system, comprising:
a head-mounted display (HMD), configured to be fixed on a head of a user, and comprising:
a plurality of first cameras, configured to capture an environment to obtain a plurality of first frames, wherein the environment comprises an object;
a storage device; and
a processor, configured to access an object detector stored in the storage device to execute the object detector, wherein the processor inputs the first frames and a first map data of each of the first frames into the object detector; and
a tracker, configured to be fixed on a limb of the user, and comprising:
a plurality of second cameras, configured to capture the environment to obtain a plurality, of second frames;
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.
