PROBLEM TO BE SOLVED: To provide a marker analysis method for determining a flat surface and a curved surface and also determining whether a flat surface is a folded flat surface.SOLUTION: There is provided an analysis method in the case where a marker 2 is stuck on a surface, the marker including a pair of first point groups 3 each of which consists of a plurality of points 31 arranged in a line and which are arranged substantially in parallel with each other and a pair of second point groups 4 each of which consists of a plurality of points 41 arranged in a line in a substantially vertical direction to the lines of the first point groups 3 and which are arranged substantially in parallel with each other. On the basis of image data, at least one piece of data on the pair of first point groups and at least one piece of data on the pair of second point groups are acquired. On the basis of at least one piece of the data on the first point groups and the second point groups, it is determined whether the surface on which the marker 2 is stuck is a flat surface or a curved surface.SELECTED DRAWING: Figure 1 |
