Title:
METHOD FOR CALCULATING DISTANCE BETWEEN GOLF MARK POINT TO HOLE CUP, AND COORDINATE SIZE BOOK
Document Type and Number:
WIPO Patent Application WO/2021/097883
Kind Code:
A1
Abstract:
A method for calculating the distance between a golf mark point and a hole cup, and a coordinate size book. The method comprises: unifying green coordinates and fairway coordinates in the same coordinate system; obtaining coordinates of a mark point and coordinates of a hole cup in the same coordinate system and marking same in a coordinate size book; then designing a coordinate difference distance quick reference table; and then calculating the difference between the two coordinates according to the acquired coordinates of the mark point and coordinates of a green hole position map, and next, obtaining, from the coordinate difference distance quick reference table, the distance between the mark point and the hole cup.
