Online correction method of position and orientation parameters of single transmitting station for indoor measurement positioning system

The invention belongs to an industrial onsite large-scale three dimensional coordinate measurement method. To raise measurement efficiency and reduce measurement errors, the technical scheme adopted in the invention is an online correction method of position and orientation parameters of a single transmitting station for an indoor measurement positioning system. The method provided by the invention comprises the following steps of: 1, arranging the transmitting station in the workspace; 2, installing more than 4 receivers for correcting the position and orientation of the single transmitting station in the workspace, wherein supports for installing the receivers are made from an invar or ceramic material with low temperature coefficient and is fixedly connected on the foundation of the station; 3, measuring coordinate figures of each receiver for correcting the position and orientation, and storing the measurement result in a host computer as a benchmark value; 4, constructing two constraint relation equations of a light plane and the receivers; 5, adopting quaternionic correction delta qTXGn, coordinate correction delta PTXGn and the position and initial positioning orientation parameters of the transmitting station to calculate novel position and orientation parameters R'TXG and P'TXG of the transmitting station after the variation of the position and orientation parameters through the formula (5) and the formula (6). The invention is mainly applied in the three dimensional coordinate measurement.
