Thought -read chi group

The utility model provides a thought -read chi group, including prism, connecting rod and scale, prism, connecting rod and scale all are provided with a plurality of, two liang of interconnect on a plurality of scale form a hollow structure, and a prism is all connected through the connecting rod to every scale. But thought -read chi group according to actual need suitably assembles and installs on the object that awaits measuring, gets prism spatial position data through using the total powerstation to survey, according to thought -read chi group's prism and the object that awaits measuring relative spatial position within a definite time, tries to achieve the central spatial position data of object that await measuring again. The utility model has the advantages of simple structure, simple to operate, but according to actual need independent assortment to can used repeatedly, reduced the quantity of making different assistant measuring apparatuses for different specific objects alone, simultaneously the uti
