With the state vector at given time t expressed by xt = (x, y, ψ),
the likelihood of state vector xt is acquired by matching LRF
measurement results to 3D voxel environment maps. This is
combined with DR through particle filters to acquire the
determined state vector xt.
Using the time-sequential set of LRF measurement results
until time t expressed by z1:t and measurement results from
sensors for DR by the odometer and gyroscope expressed by
0:t1 u , the probability 1: 0: 1 , t t t p x z u of state vector xt of the
mobile robot at the given time t is formulated by the
recurrence formula Eq. (6), where t t p z x is the probability
distribution of the measurement model and 1 1 , t t t p x u x is
the probability distribution of the motion model.
presents our conclusions.
