Abstract
By determining a center physical grid dot at intersects of virtual grid lines of a fetched scene on an encoded dotmap, and by defining a blank dot closest to the determined center physical grid dot on the fetched scene, the orientation of encoded blocks on the encoded dotmap may be determined. And therefore, a plurality of data dots on the fetched scene may also be decoded easily.
