  • Travel amount estimation device and travel amount estimating method
    Patent number: 9483841
    Abstract: A processor generates a first road surface image from an image at a first time captured by an imaging device mounted on a moving body, and generates a second road surface image from an image at a second time after the first time. Next, the processor determines direction information depending on a direction of travel of the moving body between the first time and the second time from an amount of turn of the moving body between the first time and the second time. Then, the processor determines a relative positional relationship between the first road surface image and the second road surface image by using the amount of turn and the direction information, and determines an amount of travel of the moving body between the first time and the second time on the basis of the relative positional relationship.
