Abstract:Laser tracker with high accuracy is often used to survey with known control points in process of application.For meeting the demands of track geometry parameter measurements,a kind of connection device and surveying method was introduced.The device connects SMR target sphere and track control points installed optical reflector SMR target sphere and is used in the place where the track control points are known.The method is to survey the position difference between SMR target sphere and the center of Leica prism.The relevant specifics precision index of the two kinds of prisms is given.
