Method and arrangement for calculating a conformity between an estimated representation of an environment and the actual environment
First Claim
1. A method for calculating a conformity between an estimated representation of an environment and an actual environment, wherein said representation of the environment constitutes a representation in at least two dimensions, where a distance between two points in the representation has a known relation to the corresponding distance in said environment, wherein the method comprisesestimating a first position for a point on a vehicle in said representation of the environment based on a mathematical model of the vehicle and stored data and, calculating a first set of expected parameter values for said first estimated position in said representation of the environment,comparing said computed first set of expected parameter values with a second set of stored parameter values, where said second set of stored parameter values has been determined for a second position, where said second position constitutes a position in said environment that essentially corresponds to said first estimated position, andusing said comparison for calculating a measure of a conformity between said actual environment and said representation of the environment.

Abstract
The present invention concerns a method for determining a conformity between a representation of an environment and said environment, wherein said representation of the environment constitutes a representation in at least two dimensions, where a distance between two points in the representation has a known relation to the corresponding distance in said environment, characterized in that said determination involves the step of determining a first set of parameter values for a first position in said representation of the environment, comparing said first determined set of expected parameter values with a second set of parameter values, where said second set of parameter values has been determined for a second position, where said second position constitutes a position in said environment that essentially corresponds to said first position, and using said comparison to determine a measure of conformity between said environment and said representation of the environment. The invention also concerns an arrangement and the mining and/or construction machine.

1. A method for calculating a conformity between an estimated representation of an environment and an actual environment, wherein said representation of the environment constitutes a representation in at least two dimensions, where a distance between two points in the representation has a known relation to the corresponding distance in said environment, wherein the method comprises
estimating a first position for a point on a vehicle in said representation of the environment based on a mathematical model of the vehicle and stored data and, calculating a first set of expected parameter values for said first estimated position in said representation of the environment, comparing said computed first set of expected parameter values with a second set of stored parameter values, where said second set of stored parameter values has been determined for a second position, where said second position constitutes a position in said environment that essentially corresponds to said first estimated position, and using said comparison for calculating a measure of a conformity between said actual environment and said representation of the environment.

10. An arrangement for determining a conformity between an estimated representation of an environment and an actual environment, wherein said representation of the environment constitutes a representation in at least two dimensions, where a distance between two points in the representation has a known relation to a corresponding distance in reality, wherein said arrangement comprises:
-
means for estimating a first position for a point on a vehicle in said representation of the environment based on a mathematical model of the vehicle and stored data, and, calculating a first set of expected parameter values for said first estimated position in said representation of the environment, comparing said first set of expected parameter values with a second set of stored parameter values, where said second set of stored parameter values has been determined for a second position, where said second position constitutes a position in said environment that essentially corresponds to said first estimated position, and computing a measure of a conformity between said actual environment and said representation of the environment based on said comparison. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
