Method and device for determining the reliability of an estimated position for a mining and/or civil engineering machine

摘要

The present invention concerns a method and a device for calculating the reliability of an estimated position for a point on a mining and/or construction machine, wherein estimation of said position involves an estimation based on at least a first parameter value from at least one sensor and a representation of the environment where said machine is located, wherein said machine's position in said environment can be estimated by means of said at least one first parameter value. Said calculation of the reliability involves - calculating, from said estimated position in said representation of the environment, at least one second expected parameter value, - comparing said calculated at least one second expected parameter value with at least one actual parameter value for said machine's position in said environment, and - calculating with the help of said comparison a measure of the reliability of said estimated position.
