PROBLEM TO BE SOLVED: To reset simply to a correct identification state, when an index having no ID is identified wrongly. SOLUTION: A method has an index detection step for detecting images of one or more index candidates from imaged images imaged by a plurality of imaging devices, and determining the position in a space of the index candidate by performing correlation between the images; an index tracking processing step for tracking the index candidate detected in the index detection step; a timing input step for entering timing of execution of identification reset processing; and an identification reset step for performing re-identification of the index based on a height range in a space defined to each index when input is performed in the timing input step, and on the height in the space of the index candidate.
