| description | The invention discloses a measurement method for reverse hierarchical control of an accurate measurement network of an existing railway. The measurement method comprises the following steps: measuring an online CPIII control pile, and measuring an online encrypted CPII control pile and an online encrypted benchmark in parallel; a first constraint point is selected to carry out adjustment on measurement data of the online encrypted CPII control pile and the online encrypted benchmark, and a temporary plane result of the online encrypted CPII control pile and a temporary elevation result of the online encrypted benchmark are obtained; adjusting the measured temporary plane data and temporary elevation data of the offline design control network by using the temporary plane result of the online encryption CPII control pile and the temporary elevation result of the online encryption benchmark to obtain the temporary plane result and the temporary elevation result of the offline design control network; adjusting th |
