Information processing apparatus, information processing method, and non-transitory computer readable medium

An information processing method comprising:

• storing a virtual map that is three-dimensional and corresponds to a real space;
• acquiring map information of the real space from a plurality of moving bodies moving in the real space;
• extracting a difference of each piece of the map information from the virtual map;
• and
• updating the virtual map based on the difference in a case where the difference for a same place is extracted from two or more pieces of the map information.

A non-transitory computer readable medium having recorded therein a program for causing a computer to execute:

• when executed by the computer,
• storing a virtual map that is three-dimensional and corresponds to a real space;
• acquiring map information of the real space from a plurality of moving bodies moving in the real space;
• extracting a difference of each piece of the map information from the virtual map and;
• and
• updating the virtual map based on the difference in a case where the difference for a same place is extracted from two or more pieces of the map information.
