Abstract
A vehicle position attitude-angle estimation device sets a particle existent distribution range to a predetermined range by using a particle filter and disperses particles within the set existent distribution range to estimate the position and attitude angle of a vehicle from an image capturing the surroundings of the vehicle. The vehicle position attitude-angle estimation device widens the set existent distribution range in the vehicle width direction of the vehicle when the speed of the vehicle becomes high.
