Document Type and Number:
Japanese Patent JP2017215193
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an information processing device for finding the movement amount of a mobile entity with high accuracy.SOLUTION: An information processing device according to an embodiment includes a processing circuit. The processing circuit acquires a measured value that includes at least acceleration, corrects it to remove a drift included in the measured value, acquires a first image and a second image differing in acquisition time from the first image, detects a feature point included in each of the first image and the second image, searches the feature points in the second image for a corresponding point that corresponds to a feature point in the first image, and estimates the relative movement amount of a mobile entity between acquisition time of the first image and acquisition time of the second image on the basis of the corrected measured value, the feature point in the first image and the corresponding point in the second image.SELECTED DRAWING: Figure 1
