  • State vector estimation using a constraint derived from a map
    Patent number: 8892392
    Abstract: It is disclosed to estimate a state vector of an object, wherein the state vector comprises a state variable related to a position or an orientation of the object, based on at least one of a probability density function of the state vector truncated under consideration of a constraint for the state variable, wherein the constraint is derived from a map, and properties of the truncated probability density function.
    Type: Grant
