IPC: G01B11/00
Filed: 2021-06-22
Abstract: To provide a marker capable of precisely recognizing a position of a marker.SOLUTION: A position recognition part 3 of a marker 1 changes intensity of light of visual information that can be observed in an observation position according to an observation angle θ to the position recognition part 3 from an observation position. Such a change in intensity of light can be used as a parameter for showing a minute change in the observation angle θ by previously grasping a correspondence to the observation angle θ.
