1. An information processing apparatus, comprising:
a central processing control unit (CPU) configured to:
select, from a plurality of key frames, a second key frame different from a first key frame of the plurality of key frames, wherein
the first key frame corresponds to a first position of the information processing apparatus,
the second key frame corresponds to a second position of the information processing apparatus, and
a degree of uniqueness of the second key frame is higher than a degree of uniqueness of a third key frame of the plurality of key frames;
output content to guide a user of the information processing apparatus to the second position corresponding to the second key frame;
acquire, based on the output content, environment information at the second position corresponding to the second key frame; and
estimate the second position of the information processing apparatus based on the acquired environment information.
