Provided are: a marker that can achieve attitude estimation that is more stable than has been conventional by means of an unambiguous estimation of attitude at a wider range of angles; and an attitude estimation method that uses the marker. Provided is a flat marker 1 provided with: an AR marker 2; and a plurality of moiré patterned sections VMP1x, VMP1y, VMP2x, VMP2y that form pattern data in accordance with the direction of observation by means of a reticular lens (LL) provided on a striped pattern (ST), and by means of which the direction of observation can be unambiguously estimated in accordance with the observed position of the pattern data for each divided range of observation directions with respect to the pattern data. |
