Abstract
[Object] An information processing device that calibrates offset and distortion with good precision, with a small amount of computation. [Solution] Provided is a mesh control unit (22) that generates a mesh that sections, into a plurality of regions, an orientation space where pieces of magnetism data collected from a magnetic sensor (11) are arrayed, based on components of the magnetism data, and stores the magnetism data in a storage unit (30) for each section. The number of sections in contact with a vertex of each of the multiple of sections is three or less.

An information processing device that collects magnetism data from a magnetic sensor, the device comprising:
- a mesh control unit that generates a mesh that divides, into a plurality of sections, an orientation space where pieces of the magnetism data collected from the magnetic sensor are arrayed, based on coordinate components of the magnetism data, and stores the magnetism data in a storage unit in association with each section,
- wherein a number of sections in contact with a vertex of each of the plurality of sections is three or less.
An information processing method of an information processing device that collects magnetism data from a magnetic sensor, the method comprising:
- a mesh control step of generating a mesh that sections, into a plurality of regions, an orientation space where pieces of the magnetism data collected from the magnetic sensor are arrayed, based on coordinate components of the magnetism data, and storing the magnetism data for each section in a storage unit,
- wherein, in the mesh control step, sectioning is performed in which a number of sections in contact with a vertex of each of the plurality of sections is three or less.
A data structure that stores magnetism data collected by a magnetic sensor,
- wherein section data indicating a plurality of sections obtained by dividing an orientation space where pieces of the magnetism data are arrayed, based on coordinate components of the magnetism data, and a count of magnetism data stored in each of the sections, are stored, and
- wherein the section data and the count of the magnetism data are used by an information processing device, in processing of determining whether or not to continue collection of the magnetism data, based on a number of sections storing a predetermined count of the magnetism data.
