Information processing method and information processing device

An information processing device comprising:

• a computation section configured to extract a plurality of feature points and a local feature amount related to each feature point of the plurality of feature points from acquired image information;
• and
• a communication section configured to acquire a feature point list on a basis of collected observation information,
• wherein the computation section performs self-localization on a basis of the local feature amount and the feature point list,
• wherein the feature point list includes the local feature amount related to each feature point of the plurality of feature points and a three-dimensional coordinate position of each feature point associated with a unit area including an observation point of the observation information,
• wherein the acquired feature point list is generated according to a reliability of each feature point of the plurality of feature points,
• wherein the reliability of each feature point is determined according to time information related to the observation information, the time information indicating one or more times when each feature point was detected from the observation information, and
• wherein the computation section and the communication section are each implemented via at least one processor.

An information processing device comprising:

• a communication section configured to receive observation information collected around a unit area;
• and
• a list generation section configured to generate a feature point list in which three-dimensional coordinates of each feature point of a plurality of feature points are associated with a local feature amount of the feature point, each feature point of the plurality of feature points having been detected from the observation information,
• wherein the feature point list is generated according to a reliability of each feature point of the plurality of feature points,
• wherein the reliability of each feature point is determined according to time information related to the observation information, the time information indicating one or more times when each feature point was detected from the observation information, and
• wherein the communication section and the list generation section are each implemented via at least one processor.
