1. A method for manufacturing a dartboard structure, comprising:
providing a frame jig;
disposing a first sensor unit and a second sensor unit in the frame jig, and filling a colloid into the frame jig to form a dartboard frame unit; wherein the second sensor unit and the first sensor unit are in an intersecting arrangement and have a predetermined gap therebetween, and wherein the first sensor unit and the second sensor unit are not disposed on the same plane;
removing the frame jig; and
disposing the dartboard frame unit on a dartboard body unit to form the dartboard structure;
wherein the dartboard frame unit has a plurality of through openings that penetrate through the dartboard frame unit, the first sensor unit and the second sensor unit surround a plurality of first sensing regions, and each of the first sensing regions corresponds to one of the through openings.
