1. be used for by means of the method for measuring the position of mobile object based on the features location method in the mode of computer support, utilize described localization method to measure a plurality of base station (BS1, ..., BS14) feature and under the situation of using reference diagram (RM) position of anchored object therefrom, base station (BS1 wherein, ..., BS14) characteristic present is by described base station (BS1, ..., BS14) sent in the field at object place or by (BS1 that described object sent in described base station, ..., the field of BS14) locating, wherein:

  • A) when the described method of initialization, the reference diagram (RM) that comprises a plurality of nodes given in advance, described node respectively by the position ( kPos RM) and attach troops to a unit in described position ( kPos RM) the value that depends on feature ( kp RM) represent;

    B) repeatedly locate during described method in operation, utilize described location determine respectively the measured value that depends on feature ( cP) and therefrom pass through under the situation of using reference diagram (RM) given in advance, to determine the oriented position (pos of described object based on the features location method RM( cP));

    C) respectively reference diagram given in advance (RM) is carried out one or many at least a portion location and upgrade, wherein utilize correction term (S respectively UPD) to centering on object'"'"'s position (pos RM( cP)) in the specific environment the value that depends on feature at the node place of described reference diagram (RM) ( kp RM) proofread and correct wherein said correction term (S UPD) depend on the measured value that depends on feature in corresponding location ( cP) with the value that depends on feature at node place in described specific environment ( kp RM) between poor.
